This Video of the Month showcases how the application of PerforationVA, supported by Optis Infinity technology, helped a leading independent operator to optimize well completion and frac design, through a cost-effective well intervention.
Maximising the efficiency of well completion and frac design is a major challenge for the global energy industry. Ineffective design may result in over or under-stimulation, leading to under performing wells, rapid production decline and reduced ultimate recovery. Conventional diagnostic techniques such as micro-seismic, fibre optic, tracers or production logs are effective in evaluation at the stage or cluster-level, but as the individual perforations are the lifeblood of the well, effective evaluation requires information at the perforation-level.
PerforationVA provides complete understanding of proppant placement and the distribution of fracture networks. With this quantified information, it becomes possible to adjust design parameters that affect perforation erosion, thereby improving cluster efficiency and achieve an evenly distributed fracture network.
Having successfully completed a pilot to evaluate the performance of PerforationVA, a leading independent operator sought to apply the service to additional wells. However, careful consideration was given to manage the time and cost of the data acquisition operation. To enhance efficiency, EV suggested the introduction of Optis Infinity M125 technology, deployed in memory mode on standard coiled tubing, to eliminate the need for additional specialized equipment, such as E-coil or wireline tractors. Previous technology relied on a single side view camera, rotated by an electric motor, requiring start and stop operations to locate and capture each individual perforation at their specific phasing. Optis Infinity, however, is equipped with 4 cameras in the same plane offset by 90 degrees, allowing for full 360° coverage of the well in a single continuous pass, without having to stop to locate perforations.
EV’s Optis Infinity M125 tool was deployed using standard coiled tubing, immediately after well clean-out procedures were complete. Data was acquired with a single, continuous logging pass at a speed of 15ft/min and with a total operating time of <14 hours. All perforations and stages were analyzed successfully with PerforationVA, completing the objective in full. Thanks to its 360° field of view and memory recording capability, Optis Infinity M125 eliminated the need for specialized conveyance equipment and significantly reduced data acquisition time, resulting in >80% reduction in operating time and >60% reduction in conveyance cost compared with previous operations using conventional camera technologies and conveyance methods.
