This video of the month showcases how the application of RestrictionVA, supported by Integrated Video Caliper technology, helped an operator in West Texas diagnose and overcome their wellbore access problems.
An industry-wide drive for efficiency has resulted in enhanced well design of unconventional wells. Extreme-reach laterals enable operators to produce more hydrocarbons from fewer wells, but this increase in horizontal length brings with it a number of challenges.
A multistage frac operation in an extreme lateral of 23,000ft, stopped to a halt when the operator experienced an unknown obstruction at approximately 18,200ft in the production casing while pumping down their plug and perforating gun assembly for the second stage. With live guns on site and the operation on standby, the operator needed a clear understanding of the restriction and how to overcome it.
EV’s 24 arm Integrated Video Caliper was deployed on an E-Line tractor providing high definition video, combined with multi-finger caliper measurements, to help identify the causes of the hold up. EV’s Video-while-tractoring technology provides live video while tractoring, enabling real-time decision making and risk reduction during interventions in extreme reach laterals. The caliper identified a number of anomalous casing collars that have smaller ID’s than the expected drift ID of 3.795 inches.Watch the video or download the PDF Case Study to find out more.
