Abstract: |
The use of borehole imaging is a recent addition to the well logging toolkit available to the geothermal industry in New Zealand. The information acquired from borehole televiewer (BHTV) equipment, such as the Acoustic Formation Imaging Technology (AFIT) tool, provides valuable structural information about geothermal reservoirs. This paper investigates the effectiveness of acoustic borehole imaging in a geothermal environment by comparing the information from a continuous core to a BHTV log acquired using the AFIT tool. This study is unique in the New Zealand geothermal industry, as the data presented here has been obtained from the only well to have both a borehole image and continuous core. |
