  • Revolutionizing Offshore Drilling: CAN-ductor Technology Cuts Costs and Boosts Safety in the Barents Sea

    The first CAN-ductor ever to be installed was done in the Barent Sea December 2015 with great success marking a new era for the CAN technology. By integrating the conductor to the CAN it added a new value case where 2-4 rig days were removed from a typical top hole establishment in addition to being a much stronger and more reliable wellhead foundation. This summer another 3 off CAN-ductor units were installed for one of our customers as part of their exploration program in the Barents Sea. In total 4 off CAN-ductor units were ordered and turned around on an accelerated schedule ready for shipment on the quay side 1st of June. Our trusted partner, Randaberg Industries, professionally ramped up their production line to modify our rental CAN units to suite the geo-technical conditions on the locations provided by the customer. That involved primarily modifying the length of the CAN skirts and integration of the customer provided low pressure wellheads. Installation cost of any installation going subsea is normally critical to the overall project cost. Different ways for bringing the CAN units from Stavanger to the Barents Sea and installed was considered. A decision on brining the units on a coastal liner was made and all 4 units was thoroughly stacked and secured horizontally before shipped to Hammerfest and Polar Base where they were offloaded and upended on key side. The installation vessel, Olympic Ares, loaded and secured 2 off units before going out installing the units on their specific locations at roughly 400m of water. Installation time per CAN unit was in average 18 hours from vessel arrived location until leaving again after successful installation. Customer selected the CAN-ductor for various reasons: Reduced risks Safety & environment no heavy bottomhole assembly or conductor handling / lifting in red zone no in moonpool man riding no cuttings to seabed from top hole Operational risks Engineered wellhead foundation removing risk for out of verticality No wobbling wellhead due to BOP loads Extended wellhead fatigue life time Removes wating on weather for top hole section Simple cutting of wellhead during P&A Cost Removes 2-4 rig days Allows conversion from exploration to production CAN-ductor designed to be converted to production well later if found commercial discover 100% recyclable We are now working with customer to finalize last well location before the 4th CAN-ductor is installed. In the mean time we congratulates the customer with the current installation success and wishing them all the best of luck in the coming exploration drilling on these wells now just wating for the rig to arrive.

  • Neodrill WSS - Wellhead Support System

    The Neodrill Wellhead Support System (WSS) enhances wellhead fatigue protection and operational efficiency by leveraging CAN technology to create a stable subsea foundation that diverts BOP loads away from the wellhead. This system significantly reduces fatigue damage, extending the wellhead's life and lowering costs by minimizing the need for extensive equipment and logistics. Suitable for both new and existing wells, the WSS simplifies installation and retrieval processes, ensures safe P&A activities, and accommodates high-capacity connectors without deviating from standard wellhead profiles, thereby optimizing drilling and production operations.

  • Development of Shallow Reservoirs using CAN-ductor

    The CAN-ductor concept improves top hole well construction by using a suction anchor with a guide pipe, allowing pre-installation by vessel, which saves rig time and enhances flexibility. Initially developed for deep-water wells, it has proven effective in reducing installation time and ensuring well integrity by providing robust support for BOP and mitigating risks of unstable conductors.

  • Optimizing Subsea Development: The Innovation of CAN-integrator

    The oil and gas industry's evolution has always been about pushing boundaries, exploring unknown territories, and harnessing technology to unlock the earth's energy resources. At the heart of this exploration and production activity lies the critical importance of a robust foundation - particularly in subsea developments. Neodrill's CAN-integrator technology stands at the forefront of this innovation, redefining what's possible in subsea wellhead systems. In the image below the top of the CAN is fitted with OneSubsea's deflector base to the left and with Astrimar's (www.astrimar.com) design and solution to the right. Subsea Wellhead and the Innovation behind CAN-integrator Subsea wellheads are vital components in offshore drilling, serving as the interface point between the seabed and the drilling operations above. These structures must withstand extreme conditions and pressures, making their design and installation critical for the safety and success of drilling projects. Enter the CAN-integrator by Neodrill, a revolutionary approach that not only strengthens the subsea well foundation but also extends its fatigue life significantly. Derived from the original CAN-ductor technology, the CAN-integrator is engineered to support the well throughout its lifecycle, accommodating the unforeseen extension of field production life due to advancements in Enhanced Oil Recovery (EOR) technologies and the discovery of nearby resources. Advantages of CAN-integrator in Oil and Gas Field Services The CAN-integrator system introduces numerous advantages over traditional conductor systems. By design, it reduces operational costs and environmental impact. Implementations have shown that it can save operators 2-7 rig days on average, a substantial cost-saving in the high-stakes environment of offshore drilling. Moreover, the reduced need for large and heavy conductors, bottom hole assemblies (BHA), and volumes of cement not only minimizes the logistical footprint but also the project's environmental impact. Subsea Solutions and Systems Enhanced by CAN-integrator Integrating Subsea Production Systems (SPS) with the CAN-integrator has yielded considerable scope savings. The design allows for the inclusion of guide bases and flow bases directly into the CAN top, streamlining installation and reducing the need for additional structures on the seabed. This integration capability makes the CAN-integrator particularly suited for single and dual slot developments, as well as more complex daisy chain or in-line T developments. Subsea Development Strengthened by Technology The strength and versatility of the CAN-integrator have made it a preferred choice for operators looking to future-proof their subsea wells. Its ability to withstand the anticipated casing, BOP, riser, and environmental loading for the life of the field has been a game-changer, providing a level of reliability and safety previously unattainable. Sustainability and Environmental Benefits of CAN-integrator Perhaps most notably, the CAN-integrator aligns with the industry's growing commitment to sustainability. Its installation process, which eliminates the need for drilling tophole, running, and cementing conductors, significantly reduces CO2 emissions and environmental disruption. Furthermore, the system's design ensures that 100% of the CAN-integrator can be recovered and recycled at the end of the field's life, contrasting sharply with the less than 10% recovery rate of conventional conductors. Enabler for potential future rigless exploration wells With the rigless CAN-ductor well foundation, a platform for future rigless exploration well drilling is created. Leveraging the CAN-ductor further well sections may come in place by use of cheaper well intervention vessels and technologies like casing drilling and coil tubing drilling. Considering well barriers are maintained, this could be a game changer for cheaper and more environmental exploration drilling. Conclusion The CAN-integrator by Neodrill represents a significant leap forward in subsea development technology. By offering a more robust, cost-effective, and environmentally friendly solution, it sets a new standard for the industry. As we continue to push the boundaries of what's possible in offshore drilling, technologies like the CAN-integrator will be pivotal in ensuring that these endeavors are sustainable, safe, and successful. "With CAN-integrator, we say 'Yes, we CAN!' to a stronger, safer, and more sustainable subsea future."

  • Integrating NCS Building Blocks

    The Norwegian Continental Shelf (NCS) has been driven by a strong standardization process over the last decade led by the bigger operators. The purpose of this process has been to reduce costs primarily in the early phases, but generally also over the full project phase, for any field development. Standardization Outcomes The outcome of the standardizing process has been the NCS 17+ subsea production system building blocks. These consist of core elements like templates, 6, 4, 2, or single slot solutions, manifolds, vertical X-mas trees, and associated control systems. The time to start manufacturing these elements has become much shorter, and due to the reduced need for field-specific engineering, the cost has also been reduced considerably. Challenges of Standardization The drawback of standardizing is the risk of preventing innovation and technological improvements. Still, smaller incremental improvements can be achieved, allowing the combination of known technologies into new system setups. Neodrill was recently tasked to look at such an incremental development with an Operator on the NCS. Targeting Smaller Discoveries The Operator was targeting smaller discoveries around an existing operating asset and required cost-efficient solutions to ensure a stronger or sufficient return on investments in the event of a development. These discoveries typically hold marginal resources that would not justify a separate field development but would be a valuable addition to the existing production assets. Synergies with Exploration Phase Secondly, the operator would like to draw synergies with their exploration phase. If a discovery was made, the operator wanted the option to simply convert this to a production well. This would typically apply to a gas discovery primarily, but also in some cases for an oil discovery, depending on the location of reservoir penetration. Utilization of Current NCS 17+ Standard In line with current NCS 17+ standardizing, the same VXT used for template development wells should be used for these single well producers. This adds some complexity to the flowbase to allow for flow line mandrel travel, which again increases the size of the flow base. The current NCS 17+ single slot solution calls for a 4-suction pile structure for this flow base to sit on, with an associated over-trawl protection structure. Modular Solutions by Neodrill In the study conducted by Neodrill, a modular solution was found that allows for a CAN-ductor to be converted to a single slot CAN-integrator in the event the operator decides to convert the exploration well into a producer and tie it back to an existing facility. As the biggest loads on the CAN-ductor are seen during drilling with full casing and BOP/riser loads, it was not considered challenging to add an adapting structure on top of the CAN-ductor to integrate the single flowbase and VXT on top. The adapting structure will have fixed interface points towards the CAN-ductor at the bottom, and the SPS provider can interface its flowbase and VXT on the top in relation to wellhead stickup on the CAN-ductor. Future Prospects Due to the modular setup of the CAN-ductor to CAN-integrator conversion kit, Neodrill, together with the Operator, sees considerable upsides going forward in developing smaller discoveries. At the same time, they are reducing CAPEX and OPEX costs with a smaller environmental footprint by leveraging this new solution.

  • Neodrill Wellhead Support System

    Main purpose is to protect the permanently installed wellhead from fatigue life reduction during the drilling process of the well. Key features · High load capacity to withstand drive/drift-off loads · Wellhead fatigue protection · Highly efficient compared to alternative WLR (Well Load Relieve = Tethered BOP) o Less equipment cost o Less logistic cost (installation and retrieval of system) The Neodrill WSS is literally “based” on the CAN technology, where the CAN provides a stable subsea foundation for the support elements that relieve the loads coming from the BOP. In simple terms the WSS is a structural element that is placed between the wellhead and the BOP. It consists of a (high capacity) mandrel, an adapter plate, and a conventional connector in the axial direction (top to bottom) and a support frame in the lateral direction. Hydraulic jacks/tension struts warrant the installation and prevent tight manufacturing tolerances. Wellhead Fatigue Mitigation BOP loads are taken up by the WSS to a high degree and diverted into the CAN before they reach the wellhead system. This substantially reduces fatigue damage of the wellhead system during the drilling phase. Once the drilling phase is completed the WSS can be taken off, making room for the SPS equipment (such as flow base, x-mas tree, etc.). The degree of fatigue relieve depends on the relative stiffness between the well and the WSS system. This means: · The stiffer the WSS system, the lower fatigue damage inflicted into the wellhead · The more flexible the wellhead, the lower fatigue damage inflicted into the wellhead The table below shows the improvement for three different scenarios. The dimension (diameter, wall thickness) of the conductor is the main contributor to wellhead stiffness. One can see that the “more flexible” the conductor is, the higher the fatigue life factor for the wellhead system. This is of course a a relative measurement, as the absolute fatigue life of a 36"x2” conductor is higher than that of a 30"x1.5” conductor. For cases where the conductor is not selected yet (new wells), one has the freedom to choose the appropriate conductor size. However, for existing wells (see below, P&A case) this behavior is in fact good news as the WSS system can divert more than 90 % of the loads coming from the BOP. Application Case (A) – Fatigue Protection for Production Wells with CAN/WSS For wells being drilled by a CAN-ductor the implementation of the WSS is straight forward. · The CAN-ductor is installed by a CSV or AHTS vessel · The rig drills and cements the surface casing o A slim hole well program is enabled by the CAN-ductor, the 20” section may be dropped and replaced by the 13-3/8” section · The rig runs the WSS, which is connected to the CAN by ROV · The rig installes the BOP on top of the WSS and executes the drilling phase as per conventional drilling program o This phase is the main contributor of fatigue damage due to the high loads coming from the BOP o The WSS can prevent at least 80 % of the loads, which translates to fatigue life increase of a factor of 100 (or more), due to the non-linear (cubic) behavior of fatigue damage (e.g., 50 % reduction of load translates to a fatigue damage of (50%)^3 = 12.5 % fatigue damage) · Once the completion is installed, the BOP is removed, making room for SPS equipment · For cases where work-over operations are required, or for cases where the P&A activities need to be carried out while the tree is still on place an extended version of the WSS can be supplied Application Case (B) – Fatigue Protection for Existing Wells (P&A Activities) The CAN/WSS combination may also be used for P&A activities of existing wells. The process for this is shown below, and causes less cost for equipment and logistics compared to the tethered BOP method. · The x-mas tree is removed, and a guide frame is installed o This guide frame enables Neodrill to install a CAN over the existing well · Once the CAN is in place, the process continues by installing the WSS system, connecting it to the wellhead and to the CAN o All operations up to this stage are done from a crane vessel, no rig time is required · With the WSS in place it is now safe to connect a modern BOP to the well, as most of the loads of said BOP are diverted via the WSS directly into the CAN o The remaining load going into the original wellhead is less than 10 % compared to a direct connection of the BOP to the original well · Once the P&A activities are completed, the well is cut below seabed o This may be done by the rig, but can also be done by wire from a crane vessel by using the Terminator tool of BakerHughes o Neodrill cooperates with BakerHughes and has done several wellhead cutting operations in joint operations during CAN retrieval campaigns · The CAN and guide frame are recovered and may be used on the next well Application Case (C) – Drive/Drift-Off Protection for Production Wells with CAN/WSS For wells where drive/drift-off loads present a structural problem to drill a well, the WSS offers a unique possibility to utilize high-capacity connector system without changing the standard H4 connection profile between wellhead system and SPS equipment. The order of sequence is similar to Application Case (A), we will therefore only point out the small changes that are required to utilize high capacity wellhead connector system during the drilling phase. · For this case the wellhead mandrel on top of the WSS structure is replaced to a high capacity profile, e.g., DrilQuip EXeTM system · The wellhead system used on the well remains the same “old trusted” H4 profile with 27” outer diameter · By utilizing the CAN-ductor the conductor is already in place when the rig arrives · The first rig operation is to spud the well with a 26” BHA for a 20” surface casing (or 17-1/2” for 13-3/8” casing), that is cemented in place · Before the BOP (fitted with a high capacity connector) is run, the WSS (fitted with a high capacity wellhead to match the BOP) is run and connected to the CAN · The well is drilled, utilizing the structural capacity of the high capacity wellhead connector to cope with the high loads of a potential drive/drift-off scenario o The weak point for such a setup is often in the riser or flex joint, therefore above the BOP. This adds additional safety in case of a critical well control event · Once the drilling phase is completed, the BOP is disconnected and the WSS is recovered, revealing the “original” wellhead with the 27” H4 profile · The SPS equipment is then run and connected to the wellhead and the well can be set into production Summary Key advantages for all presented cases · Substantially decreases fatigue damage for exploration and production wells, increased fatigue life (depending on wellhead stiffness) of a factor of 100 and far beyond · Enables safe and efficient P&A activities of existing wells with unknown remaining fatigue life · Allows utilization of high capacity wellhead connector systems without the need to deviate from established standard connectors on the wellhead system or the SPS equipment · No need to change BOP connector during drilling campaign from high capacity to standard capacity · Avoids cost and complex logistics to use the tethered BOP system · Lowers overall well cost by saving rig time for conductor installation · Moves a good amount of rig time to less costly crane vessel time Please contact us at www.neodrill.com for further information, I’m sure we can contribute to your challenges.

  • Recycling CANs

    The United Nations' 12th sustainable development goal, Responsible Consumption and Production, is about achieving greater impact with fewer resources. In today's society, we consume far more than the planet can sustainably support. Recycling plays a crucial role in achieving this climate goal. In our daily lives, we are encouraged to recycle various items we consume, such as soda cans and bottles. This provides numerous benefits, including resource conservation, energy savings, waste reduction, reduced carbon emissions, and economic advantages. For the same reasons, Neodrill also recycles its CANs used for exploration wells. Asplan Viak conducted a life cycle assessment (LCA) comparing conventional top-hole drilling technology with CAN-ductor technology. The report concluded that the recyclable CAN-ductor technology offers clear environmental benefits compared to conventional methods. The report observed that 420 tons of CO2 per well was saved. Since a CAN can be used for up to ten wells, this translates to savings of 4,200 tons of CO2, 390 tons of steel, and 622 tons of cement. Given today's energy market, there is a strong focus on sustainability and green solutions. By utilizing innovative approaches, the oil and gas industry can become even more sustainable, enabling us to meet the environmental requirements set by the United Nations.

  • CAN Complete – from quote to installation

    Introduction In this article the process from quote to a CAN-ductor installed and ready for spud is explained. Through years of experience, Neodrill offers our clients a lean full-service Engineering, Procurement, Construction, and Installation solution. This to provide a low cost, reduced CO2 emissions, safe and cost-effective turnkey solution for the subsea wellhead foundation to our clients. The first step of the process is to know the seabed conditions of the area you want to have a CAN-ductor installed. The exact well location does not have to be decided, but geotechnical soil data from the area is necessary. Our geotechnical experts require Cone Penetration Test (CPT) and well loads data to determine the length of the CAN. The CAN’s have been installed in various seabed conditions in clay, sand, and mixed clay/sand layers. Neodrill offers subsea well foundations for exploration and production wells. Rental CAN’s are used for exploration well applications, and Neodrill carries a stock of CAN units that can be adjusted and prepared for installation in a short period of time, typically with 4-6 weeks of lead time. The rental CAN’s are re-used to keep the exploration well cost at a minimum. For production wells the CAN’s are built to fit the specific well. We are proud to provide the industry with low cost and low emissions alternative to conventional conductors. Fabrication phase for production wells CAN-ductors The CAN units can be built at suitable fabrication yards worldwide, close to the area of application. The Neodrill team will follow up and plan the fabrication, conduct quality assurance, and the coordinate logistics at the yard. The materials used for CAN fabrication are standard steel qualities, hence the lead time and costs are kept to a minimum. The CAN design is well suited for both one-off and serial fabrication, with module prefabrication adapted to the project (quantity and timeline) and the facilities at the chosen fabrication yard. The conductor is client supplied and integrated towards the end of the CAN fabrication stage. The CAN design allows for conductors from all manufacturers and suppliers. The conductor fixation to the CAN will transfer all axial, horizontal and bending loads from the well into the CAN structure, and further into the surrounding seabed. The final assembly can be vertical or horizontal, depending on the capabilities at the fabrication yard and the installation vessel to be used. Installation planning Through our marine vessel partners, Neodrill can provide an installation vessel suitable for the installation location and weight of the CAN. Our largest CAN units require an installation vessel with a 250 metric tons heave compensated crane capacity. Other types of vessels can be used such as an anchor handler. In this case the CAN will be horizontal sea fastened until its deployed over the stern of the vessel, see pictures below. The planning of the installation can start in parallel with the fabrication phase. By providing a full range of services the from fabrication to installation, Neodrill is removing unnecessary interfaces and reduce the follow-up resources required from the client. In addition to the vessel itself, Neodrill provides: Construction crew for installation Survey contractor Seafastening engineering Deployment analysis Provision of installation equipment such as ROV pumps and lifting equipment. Mobilization The chartered vessel is in most cases mobilized at the fabrication facility where the CAN’s are located along seaside for the vessel crane to reach. Neodrill will coordinate and prepare the base for arrival of the vessel. Once vessel has arrived, the CAN units can be lifted onboard and sea fastened to deck. Installation Once the CAN units are fastened to deck the transit to the well location can commence. The CAN is lowered to the installation location using the vessel crane or winch. The first phase of the CAN installation is the self-penetration phase. The CAN penetrates the seabed up to 60% of its length under its own weight, depending on the soil properties. Once most of the CAN weight is supported in the seabed, an ROV dock onto the top of the CAN and pump it to the final position. The ROV pumps out water to create a differential pressure, and with only one bar of differential pressure, the ROV can create force equal to 288,2 metric tons. This force drives the CAN into the seabed in a controlled manner. Neodrill has a track record of more than 28 installations, with a conductor inclination of less than 1 degree off vertical. For recovery of exploration rental CAN units, the crane is connected to the CAN and the ROV pumps water into the CAN while the crane is kept in constant tension to eject the CAN out of the seabed. Once clear of the seabed, the CAN is recovered to deck of the vessel and seafastened. During installation a meticulous log of the installation parameters is recoded. This allows us to confirm the geotechnical calculations and verify that the required load capacity is achieved. Neodrill also provide input to the Drilling Program to ensure that drill out procedures are considering the short conductor.
