La'a toso u'amea ose vili e masani ona fa'aoga mo le fa'aogaina i mea vaivai e pei o le oneone, omea, po'o se ma'a vaivai.Ae ui i lea, o le a le lelei i latou i iliili gaoa po o maa malo.Fa'aoga e aofia ai le viliina o vaieli, eliina, geothermal.si'osi'omaga ma su'esu'ega.Soo se taimi lava e mafai ai, e tatau ona fa'aoga e vili ai pu pailate aua e maua mai ni tipi e sili ona faigofie ona fa'amau.
3 apa'au la'a toso fasi o se tasi fasi fau o u'amea u'amea lafo ma tungsten carbide tipi tipi ma fua itu e mautinoa ai le ola umi.E 3 ona apa'au ma 3 pu fa'amulumulu.Pe a faatusatusa i le 4 apaau, 3 apaapa laa toso toso e masani ona vili vave ma malosi, ae, e puupuu le umi ma le umi.Ole saosaoa ole laulau fa'asolosolo ole la'a toso e tatau ona i le va o le 60 ma le 80 rpm ma le mamafa mama i luga ole bit (WOB).
3 apa'au la'a toso fasi o meafaigaluega taugofie pe a viliina eleele vaivai ma le loloto papa'u, ua matua fuafuaina mo le vaivai toso fausaga, e pei o Omea, Loam, Silt, Mostsoft-i-medium soilsthat i ai nisi susu, ma isi foi la'a toso bits. e fautuaina mo le viliina i Mining, Exploration, Siosiomaga, Vaivai, Geo Exchange, ma isi.
Faʻaaliga: O le lautele ma le filo o loʻo faʻaalia e pei ona taʻua i luga o le tele masani, o isi lapopoa e avanoa pe a talosaga.
