J55 K55 N80 Ola Tubing agus Casing Steel Pìob
Is e pìob stàilinn a th’ ann an còmhdach ola a thathas a’ cleachdadh gus taic a thoirt do bhallachan tobraichean ola is gas gus dèanamh cinnteach à obrachadh àbhaisteach an tobair ola gu lèir às deidh a’ phròiseas drileadh agus a chrìochnachadh.Bidh gach tobar a’ cleachdadh grunn shreathan de chòmhdach a rèir diofar dhoimhneachd drileadh agus suidheachaidhean geòlais.Bithear a’ cleachdadh saimeant saimeant às deidh a’ chòmhdach a dhol sìos dhan tobar.Eu-coltach ri pìoban ola agus pìoban drile, chan urrainnear a chleachdadh a-rithist agus is e stuth caitheamh aon-ùine a th’ ann.Mar sin, tha caitheamh còmhdach a’ dèanamh suas còrr air 70% de phìoban tobair ola.
