API 5CT J55 pahu no ka aila a me ke kinoea

ʻO ka J55 API casing a i ʻole tubing kahi mea maʻamau i ka ʻaila ʻaila. Ma muli o ka haʻahaʻa kila kila o J55,
hoʻohana ʻia no ka ʻaila pāpaʻu a me ka ʻili kinoea. Ma muli o kona kumu kūʻai haʻahaʻa ma waena o nā māka ʻē aʻe o ke kila, ʻoliʻoli nui ia
nā noi. Hoʻohana nui ʻia ka J55 API casing a i ʻole tubing i ka unuhi ʻana o ke kinoea maoli a me ka methane coalbed,
a hiki ke loaʻa maʻamau i nā pūnāwai pāpaʻu, nā pūnāwai geothermal, a me nā pūnāwai wai.
