Pane keri poka API IADC117 4 5/8 inihi (117.5mm) mō te taputapu keri
Whakaahuatanga Hua
I roto i te tukanga keri, ko te mata keri te taputapu matua hei wawahi i te toka, ā, ka hangaia te poka wai mā te mata keri e wawahi ana i te toka. Ko te pai o te hanganga o te poka wai me te roa o te wā e pau ana, ehara i te mea e pā ana ki ngā āhuatanga o te toka i roto i te hanganga keri me te mahi a te mata keri tonu, engari ki te nui o te ōritetanga i waenga i te mata keri me te hanganga. Ko te whiriwhiri tika i ngā mata keri he mea nui ki te whakanui ake i te tere o te keri me te whakaiti i te utu whānui o te keri.
Ko te mata keri tētahi o ngā taputapu nui mō te mahi keri hinu. He mea nui te urutau o te mata keri ki ngā āhuatanga o te toka me tōna kounga i roto i te whiriwhiri i te hangarau keri, inā koa mō te kounga o te keri, te tere o te keri me te utu o te keri.
