... rates would have provided a different flow profile compared with normal operating rates. As a result of deploying DFOS, data could be acquired at more realistic rates. Through performing thermal inversion of the DTS data and analysis of the DAS data a more accurate flow profile was achieved...

... Abstract A well intercept operation has the scope to drill into an existing well. Similarly, some infill drilling operations are conducted with the scope of avoiding interception with other wells. A prototype of a tool for Active Magnetic Ranging While Drilling (AMR) without the use...

... the engineering control volume, as shown in eq. 2 . Abstract As political, environmental, and social pressures build, oil and gas operators are searching for ways to effectively reduce methane emissions. The first step to emission reduction is to understand the current state of facility emissions, which...

This paper will present an approach to planning, implementing, and sustaining operational digital twins, that is designed to maximise the asset owner's return on investment by putting the necessary focus on the people, process, and data elements, as well as addressing the technology. A review of project...

This analysis helps answer questions such as "Are there any significant deviations from expected values that could indicate blockages, leaks, or pump inefficiencies?" and "Is the pump operating within the desired...

... require geotechnical surveys, support vessels, and tugs, take approximately 10-12 days per well remediation. Jack up rigs were approximately 200,000 USD per day (2022) according to the operator. An alternative method to service these wells uses saturation divers with a multi-string hot tapping unit...

... operation cable requirement onshore grid substation So far, the UK has successfully met its first two carbon budgets (2008-2012 and 2013-2017) and is on track to meet the third (2018-2022). However, the level of emissions reduction for the subsequent three carbon budgets will depend...

... was to establish quantitative input to the assessment of expected future well intervention requirements for the subsea oil producers and water injectors, based on historical operational data captured for the wells on this deepwater field. The specific activities for the study were: Collect data for the wells...

Thus, characterising all the impurities and determining the required purity of the CO 2 mixture is critically important for the safe design and operation of CCS transport and storage systems. It is important to note that CO 2 specifications relate to normal operations. Short-term...

... This paper will outline the engineering design and operational planning involved in the novel application of this technology. It will detail the feasibility studies conducted and explain the rationale behind the unique installation method selected, using the rig drawworks to lift the unit...
