HOW AN UNPLANNED PIPELINE SHUT-IN CAN INCREASE PRODUCTION
BHP TRANSIENT DATA OBTAINED FROM 33 WELLS SIMULTANEOUSLY
| During a field-wide shut-in for unplanned pipeline repairs, an operator performed surface
bottom hole pressure transient build-ups on 33 deep Wilcox wells in South Texas. A number of the
wells were marked as depleted wells. After obtaining a 72-hour build-up, with electronic surface
quartz gauges, 9 of the 33 wells were identified as re-frac candidates. The operator re-stimulated
all 9 wells, increasing production by 15 MMCFD and adding 8 BCF additional recoverable reserves. The EBOT electronic surface gauge is the only way to obtain this much pressure transient data from 33 wells simultaneously. |
