Folasaga
O samala DTH mai le JCDRILL e ofoina atu le fa'atinoina o fa'atinoga i le lu'itauina o le Geothermal ma le Waterwell.Ole mamanu malosi ole piston e matua'i fa'aleleia atili ai le ola ole piston ma totonu ole ola ile viliina i lalo ole koluma vai.O se fale latina e mafai ai e le vili ona fetuutuuna'i le leo o le ea e ala i le samala ina ia fa'amalieina le aveeseina o tipi.fa'ateleina le ola galue ma e talafeagai mo le fa'agaioiga i le mamafa o le ea e o'o atu i le 30 pa (435 psi).
Fa'amanuiaga a le DTH Hammers:
1. Faʻataʻitaʻiga faigofie ma talafeagai, faigofie ona faʻapipiʻi ma faʻapipiʻi, maualalo faʻafitauli faʻafitauli.
2. Fa'atauva'a le ea, lamolemole lamolemole, maualuga le malosi o le a'afiaga, maualuga le ulu.
3. Tele sa'o vevela-togafitiga ma vaega samala uma e maua ai le umi o le olaga i lalo o tulaga faigata galuega.
