Isikrini sequla le-oyile esamkelwe kunye nesakhiwo esikhulu sohlobo lokuvula, senziwa ngenxeba lentsimbi engenasici kwaye idityaniswe.
Imveliso ijolise kuqhankqalazo lwezixhobo ze-downhole kunye nomphezulu ngokuqinisekileyo imveliso egudileyo kunye nokwandiswa komjikelo wokuvelisa we-oyile, igesi kunye namaqula amanzi ngendlela ye-vgravel pade ukulawula iisanti yokwakheka.Izixhobo zayo zokulawula isanti ezisetyenzisiweyo zibambe indawo ekhokelayo kwishishini le-oyile inkqubo elula, ukufikeleleka okulungileyo ukumelana nobushushu ubomi obude obuthembekileyo ngokukhuselekileyo, kunye neendleko eziphantsi.
