(1) Bolaea hantle ho latela litlhoko tsa moralo oa moralo.

(2) Lokisetsa lisebelisoa tsa seliba le ho kenyalisebelisoa tsa ho itokisetsa ka katleho bakeng sa thibelo ea ho phatloha.

(3) Pele ho qhomisoa, mokotla o tlameha ho fetaka seliba ho ea ka melao ea tsamaiso, ho hlatsoa lehlabathe seliba ho ea botlaaseng ba maiketsetso ba seliba.

(4) Khatello ea casing e tlameha ho lekoa le cohloekisoa pele seliba se secha se phunyeletsoa.

(5) Phoso ea botebo ba ho phunya sholo ha ea lokela ho feta 0.1m.

(6) Haeba mitha ea ho phunyeha e feta 3m,seliba se ka phethoa feela ka mor'a hore khoele ea phala e hlatsuoe.

(7) Seliba sa liner se tlameha ho lekoa aka mor'a perforating, molumo oa extrusion o moholo ho feta 1m³, khatello ea extrusion e ka tlase ho 15MPa, 'me nako ea extrusion ha e ka tlase ho 5min.

(8) Nakong ea ts'ebetso ea perforating,ho lokela ho ba le motho ea khethehileng ea lokelang ho hlokomela seliba, ho thibela lintho tse oelang, le ho ela hloko hore na ho na le pontšo ea oli le khase.Haeba ho fumanoa ho khaphatseha, ho tlameha ho emisoa ho phunyeha, khoele ea pipe e lokela ho tšoaroa hang-hang, 'me khatello ea mokelikeli oa mokelikeli e lokela ho lokisoa pele e phunyeletsa.

(9) Ts'ebetsong ea kanono, haebaho na le khanyetso, u se ke ua ba thata, u lokela ho beha pele cannonball, 'me u nke mehato e lumellanang ka mor'a ho ithuta boemo ba ka tlas'a lefatše.

(10) Nakong ea kaho eohlets'ebetso ea ts'ebetso, sehlopha sa workover se tlameha ho sebetsa haufi-ufi le sehlopha sa perforating ho finyella setlolo se sireletsehileng, 'me ha ho li-fireworks tse lumelloang ho pota-pota seliba.

(11) Pokello ea lintlha tsa Perforation:

① Hlahloba kaho ea ho phunya calintlha;

② Lekanya boima ba metsi a bolaeang;

③ Mokhoa oa ho penta ka bobeli ke sethunyape;

④ Sebopeho se bulehileng, nako ea seliba, palo ea holes, emissivity;

⑤ Se bontšoang ka mor'a ho phunyeha;

⑥ Perforating nako le ho matha taelo;

⑦ Maemo a mang a khethehileng.
