The gravity method was applied in three wells in Hawaii to estimate density and porosity logs. The wells are the Schofield shaft on the island of Oahu, the Kihei no. 3 shaft on the island of Maui and the Pahala shaft on the island of Hawaii. The method determines the 'averaged' density and porosity values for Hawaiian rocks. On Oahu, the density at depth is 2.4 gm/cc and the corresponding porosity is 18%. For Maui, the density averages about 2.4 gm/cc and porosity at 17%. The Hawaii shaft shows a lower density of 2.0 gm/cc with a corresponding higher porosity of 27%. All these values are based on a grain density of 2.9 gm/cc. (Author)
