Investigation and evaluation of geopressured geothermal wells

This group of wells-of-opportunity (WOOs) consists of four reentry candidates located in Southern Louisiana. The four Louisiana wells have penetrated a thick section of deep hot and geopressured Miocene or Oligocene sand. Thus the geologic risk is essentially eliminated. Each of these wells has been abandoned. Particular emphasis was placed on selecting wells which are reported to have been left in such a mechanical condition that the risk of reentry operations is low. Every effort will be made to further check any well chosen for unreported conditions. Description, reentry proecdure, testing procedures, and cost estimates are presented for each well. (MHR
