Houston-based Vaalco Energy restarted production at the Avouma 2-H well on the Avouma platform, offshore Gabon, after utilizing a hydraulic workover unit to replace a failed electric submersible pump (ESP) system.

The well is currently producing at a stabilized rate of 2700 b/d gross (730 b/d net to Vaalco), the company said.
The ESP systems failed in both the South Tchibala 2-H and the Avouma 2-H wells on the Avouma platform this past summer.
In late-December, Vaalco put its South Tchibala 2-H well back online, by also using a hydraulic workover unit to replace a failed ESP system.
With the addition of the two recent workover wells, the total company net production is currently averaging 4600 b/d.
Prior to shut in at the Avouma 2-H well due to the ESP system failure, the well was producing approximately 2400 b/d gross (650 b/d net to Vaalco). Following completion of workover operations on the South Tchibala 2-H, workover operations on the Avouma 2-H were completed and the well was put back on production. All personnel and equipment utilized during the combined operations on the two wells have been demobilized. The detailed inspection of the failed ESP components continues and it is expected that the cause of the failures will be determined during Q1 2017. Monitoring of ESP operation and production optimization procedures continues for both wells, Vaalco said.
“Following the successful workover of the South Tchibala 2-H well, we are pleased to have also restored production from the Avouma 2-H well at a higher rate than when it went offline this past summer,” Cary Bounds, Vaalco CEO said. “We have once again demonstrated our ability to safely and successfully conduct well interventions utilizing a hydraulic workover unit. Our net production has risen to approximately 4600 boe/d, our highest rate since early summer 2016.”
