Welltec adapts valves for revised West Africa well

Offshore staff

COPENHAGEN, Denmark – Welltec has adapted its Flow Valve technology to solve various issues for a drilling campaign offshore West Africa.

“The operator had developed a new well in a new field and expanded its objectives from producing first gas to producing first oil and gas,” said Kevin Giles, Europe Area vice president.

Welltec proposed five flow valves with three different sized flow areas, which it supplied in combination with its Well Stroker and Well Key tools, both modified to meet requirements for the well.

The well operation proceeded to plan until a third-party fracturing sleeve failed to open, despite multiple attempts using coiled tubing.

By applying modeling to evaluate an option for fracturing through the flow valves, Welltec determined this would not affect the valves’ function.

In practice, the flow valve configurations gave the operator multiple options to optimize production.
