Currently picking up bottom-hole assembly
, including log while drilling equipment ("LWD"), to drill ahead.
A wireline system will cost from $75,000 to $125,000, depending on the outside diameter size of the non-magnetic bottom-hole assembly
and type of probe.
He says that the technological adaptation was made possible by careful analysis of bottom-hole assembly
procedures in oil drilling, combined with an advanced computer modeling capability.
Gammaloy and Marlex rent and lease non-magnetic drill collars and other downhole tools used within the bottom-hole assembly
, and provide manufacturing and support services for various downhole tools requiring high-precision machining.
Currently we are working to free the bottom-hole assembly
prior to drilling ahead.
Having successfully commenced drilling the build-up section of the well, and having penetrated what appears to be a significant fracture in the reservoir, Weatherford encountered repeated problems with the bottom-hole assembly
("BHA") which ultimately resulted in the BHA detaching and being left in the hole.
