Sneak Preview: March/April DC takes operator MWD/LWD criticism, challenges to service companies

Posted on 20 March 2009

Not only can vibration educe ROP, it can “twist” the borehole, producing “false” images through the LWD, an operator said.

While today’s MWD/LWD systems work even in the upper range of well temperatures and pressures, cutting-edge HPTP projects will demand even better performance – to as high as 200°C (400°F) and 35,000 psi.

However, service companies point out that the niche status of HTHP wells increases R&D cost and risk.

Fluid sampling is another item on operator wish lists, for which one manufacturer says it may soon introduce a “game-changing” solution.

Finally, reliability. “The biggest value impact from LWD/MWD/DD is to get it right the first time,” one operator noted. Reliability can suffer from component failures, QA/QC and human error.
