ADAPTING TO THE TRANSITION
Under the Paris Agreement, the goal to limit global warming to below 2 degrees Celsius has been established. The world aims to become climate neutral by 2050, establishing an economy with net-zero greenhouse gas emissions. To achieve this, the global energy sector must work together to transition from fossil-based to zero-carbon energy sources, reducing energy related CO2 emissions and limiting the impact of climate change.
This energy transition has caused a shift in the needs and wants of investors, consumers and operators who engage with the oil and gas supply chain. They now seek clear commitment and action to help reduce emissions and reach a net zero target.
Advancements in technology has made this possible. The rising demand for safe, secure energy supply due to the growing population has meant that the oil and gas industry remains a vital part of the energy mix. The need for technologies that will counterbalance this demand and help companies globally reach their net zero targets has become a necessity.
OUR ROLE IN THE TRANSITION
Our innovative technologies across the well life cycle are helping global operators reduce emissions on drilling and end of life projects through increased predictability and efficiency.
Our suite of solutions ensures the successful landing of casings and completions to target depth on first attempt. We help operators achieve reductions in net well greenhouse gas emissions through significant project time savings.
Our simple, sustainable, and innovative technologies consist of four key tools: the TurboRunner™, the TurboCaser™, the MechLOK Drill Pipe Swivel™ and the newest addition to the suite, the Rubblizer™. Our customers have recorded that the use of these tools delivered an average project time saving of at least three days, saving approximately 900MT of CO2 emissions on an offshore platform, 210MT of CO2 emissions on an offshore semi-submersible platform and 90MT of CO2 emissions on a land rig.
OUR TECHNOLOGY'S ROLE IN THE TRANSITION
The TurboRunner™ is a high-speed, turbine-powered reaming system that enables completions to be landed at target depth and access planned reserves. This transformational tool is 70% more efficient compared to conventional technology. Its unique design means it can effectively ream through obstructions that other technologies cannot, resulting in fewer wiper trips.
The TurboRunner™ was successfully used on a Tengiz Chevron Oil (TCO) project. Schlumberger Completions required a de-risked approach to ensure the lower completions could reach target depth. Deep Casing Tools was chosen by both TCO and Schlumberger to provide effective reaming tools. The TurboRunner™ helped eliminate the chance of formation issues that would lead to a completion deployment off target depth or having to undertake remedial work then a re-run of the completion. The tool saved 48 hours of time on this project equating to a total of 60MT CO2 emissions saved.
Another high-speed, turbine powered system, the TurboCaser™ is used in well construction to land casings and intermediate liners at target depth in even the most complex wells. By reaching target depth on first attempt, the solution reduces the risk of pulling and re-running, saving average of three days per drilling project and increasing efficiency by 75% compared to conventional technology.
The TurboCaser™ tool was recently deployed as part of an extended field trial. Overcoming casing running challenges, the tool ensured production casing was run to depth through unstable formations that have historically proven problematic. The use of the TurboCaser™ successfully saved seven days of rig time. Such a significant reduction in rig time saved a total of 900MT CO2 emissions, an 87% reduction compared to conventional tools.
MechLOK Drill Pipe Swivel™
The world’s first mechanically lockable drill pipe swivel, the MechLOK™ guarantees getting completions to target depth safely on first attempt. Typically designed for Extended Reach Drilling (ERD) wells, the MechLOK™ allows the drill pipe to be rotated independently of the work-string resulting in reduced drag, redistributed friction and mitigation of helical buckling. This unique tool can be locked at any time, removes any hydraulic concerns, and reduces the risk of injury during completions by around 70% due to the minimum manpower requirement.
As part of an Extended Oil Recovery (EOR) programme, an International Operating Company (IOC) required to workover an existing extended reach horizontal sand face completion to resolve a sand ingress concern which was chocking production. The MechLOK™ enabled the application of additional weight to slide the completion to target depth in a tight clearance hole, mitigating the need to pull out of hole, make an additional well bore clean up trip and re-run the completion
Awarded the ‘Emerging Technology’ award at the Offshore Achievement Awards in 2020, this tool transforms both plug and abandonment and slot recovery, improving the efficiency and predictability of cut and pull or perf and squeeze operations.
Using simple pressure and rotation to manipulate the existing casing strings, the Rubblizer™ breaks down the bond between cement and casing and the structure of the cement, making it easier to remove the casing quickly and efficiently. This avoids the need for costly milling operation and subsequent lost time issues and guarantees pulling success rates.
During early trial runs of the Rubblizer™ with a major operator, we demonstrated a project time reduction of at least ten days compared to the use of alternative, conventional technologies. By reducing rig time by ten days, emission savings can be made of at least 3,000MT CO2 on an offshore platform, 700MT CO2 on an offshore semi-submersible platform and 300MT CO2 on a land rig.
