Kuboola ndi njira yopangira mabowo mu casing (kapena liner) kuti alumikizitse mosungiramo madzi obowoleredwa bwino ndi kulola ma hydrocarbons kulowa m'chitsime. Mfuti zoboola ndi ma charger zimagwiritsidwa ntchito kuboola mabowo m'mabowo. Pamalo otseguka, mfuti zimatsitsidwa mchitsime pogwiritsa ntchito chingwe chamagetsi (E-line) kapena chubu. Mfuti zimathamangitsidwa mpaka kuya komwe kumafunikira, kenako ntchito yoboola imayamba. Pali mitundu ingapo ya zida zamfuti zomwe zilipo kuti zisankhidwe, kutengera zomwe zili pansi pa nthaka komanso zoboola.
Pali njira zazikulu zitatu zotumizira mfuti kuti mutsitse mfuti pachitsime, monga pansipa:
1) Kupyolera mu-Casing Perforating imagwiritsidwa ntchito isanamalize chitsime kuti ikhale ndi mfuti zazikulu. Kukula kwa mfuti nthawi zambiri kumakhala pakati pa 3 "ndi 5" m'mimba mwake ndipo kumayendetsedwa ndi waya. Njira yoboolayi imagwiritsidwa ntchito kuti ilowetse kwambiri chifukwa chakukula kwa mfuti. Komanso, omwe amatchedwa "mathirakitala" amathanso kutumizidwa kuti mfuti zilowe m'zitsime zopotoka. Chimodzi mwa ziletso zazikulu zogwiritsira ntchito njirayi ndi kupendekera bwino ndi kukakamizidwa, mwachitsanzo ngati pakufunika kusamala.
2) Tubing Conveyed Perforating (TCP) imagwiritsa ntchito mfuti zomwe zimamangiriridwa ku chubu (chitoliro chobowola, machubu opindika kapena machubu opangira). Ubwino waukulu wa njirayi ndikuti umalola kusiya machubu opangira m'chitsime, pambuyo pobowoleza (kuthamanga limodzi ndi chingwe chomaliza), nthawi yayitali komanso yotalikirana, komanso kugwiritsa ntchito zitsime zopotoka kwambiri komanso zopingasa. Chotsalira chachikulu cha mfuti za TCP ndi mpaka kutsirizidwa kubwezeredwa (kuyambiranso ntchito) mfuti sizingatengedwe. Chifukwa chake, kudalirika kwamfuti za TCP ndikofunikira kwambiri, chifukwa vuto lililonse limapangitsa kuti ntchito ikhale yopanda pake komanso kukhudza kwambiri mbiri yamtsogolo.
3) Mfuti za Perforating Mfuti ndi mfuti, zazing'ono kukula kwake, zomwe zimagwiritsidwa ntchito m'zitsime zomalizidwa ndikudutsa m'machubu opangira. Dongosololi ndi lotsika mtengo ndipo limalola kuphulika kocheperako, komabe limapereka malowedwe ochepa.
Makina amfuti amagawidwa m'magulu awiri:
1) Mfuti zowonekera (Kapsule) ndi
2) Mfuti zonyamulira zopanda pake. Mfuti zonse zimayambitsidwa ndi magetsi pamtunda ndipo zimabwera mosiyanasiyana kuti zigwirizane ndi zofunikira zonyamula bwino.
