Case Study: Lonestar Resources Ltd. optimizes coiled tubing cleanup and preserves fracture integrity with SLB AvantGuard flowback services
A SLB Case Study
AvantGuard Advanced Flowback Services Help Lonestar Determine Optimal Coiled Tubing Operating Conditions
SLB worked with Lonestar Resources Ltd. to address a coiled tubing millout challenge in an Eagle Ford Shale horizontal well. The goal was to avoid proppant mobilization from the fractures while optimizing plug removal and wellbore cleanup during poststimulation operations.
SLB integrated its Vx Spectra surface multiphase flowmeter with the coiled tubing campaign to monitor water, sand, and gas returns in real time. The data showed the well was underbalanced for much of the job, with gas production and 23,000 lbm of sand recovered, so SLB recommended future millout operations in slightly overbalanced conditions to preserve fracture integrity and reduce disposal costs while improving long-term recovery.
