API 5CT J55 casing bakeng sa oli le khase

The J55 API casing kapa tubing ke ntho e tloaelehileng ho cheka oli. Ka lebaka la tšepe e tlase ea J55,
e sebelisoa bakeng sa ho ntša oli e sa tebang le khase. Ka lebaka la theko ea eona e tlase har'a lihlopha tse ling tsa tšepe, e thabela ho feta
lits'ebetso. The J55 API casing kapa tubing e sebelisoa haholo ha ho ntšoa khase ea tlhaho le coalbed methane,
’me hangata e ka fumanoa lilibeng tse sa tebang, lilibeng tsa mocheso o phahameng oa lefatše le lilibeng tsa metsi.
