| Abstract |
Well ZD-1 the first of a series of three development wells planned for the Zunil I field,was drilled and completed to a depth of 1516 m. well successfully met its objective encountering a zone of high temperature and high permeability near m-1,475 m depth, within crystalline basement rocks.ZD-1was drilled toa depth of 730 m, then it was directionally drilled towards its target, south of the wellhead location. The well reached a maximum drift angleof 13 to 15 with a true vertical depth of 1,497 m,and the location is 158m south and 23 m east of the wellhead. high permeability was found in the granodiorite, beginning at m.This is expected to be the production zone for ZD-1. The injectivity index is cu .From the vertical discharge, an initial productivity of about 14 was estimated. |
