Fluid injectivity was lost in a field waste disposal well, halting operations. A CT cleanout was planned to restore functionality. During the initial stage, the CT became stuck after fluid returns were lost, creating an urgent challenge.
The goal was to free the coiled tubing string without resorting to a lengthy and costly pipe recovery operation. This required rapid decision making and precise execution under high operational complexity.
The IDEX platform aggregated real-time data from multiple sources into a single dashboard, enabling onshore and offshore teams to collaborate effectively. Analysis revealed that fill in the annulus between the CT and completion tubing was preventing movement.
Using the IDEX platform, the team implemented a series of freeing techniques, including fluid changes, weight manipulation, and pressure cycling. Each attempt was tracked and optimized based on live feedback. At a critical stage, additional options were identified through data review, delaying a wireline retrieval operation and enabling further freeing attempts.
Ultimately, the CT string was successfully freed, saving days of intervention time and avoiding a highly complex recovery process.
