Re: Completion Questions for the Oil Experts
There is a lot of heavy duty engineering that goes into the hpht ud completions. Too complex for a message board post unfortunately. Well design comes down to the ability to seal pressure and fluid / gas movement within metallic systems so that it goes where you want it to go while protecting from uncontrolled release. These systems go through immense thermal expansion and are under extreme pressure. Consider too that all the pipe that goes in the hole has to remain within available rig weight / torque capacities. These ud hpht wells are stretching the limit of existing equipment designs and rig capacities. The deeper you go, the less options you have.
