Abstract
AbstractThe DuPont Victoria Texas plant has gained 195 well‐years of experience in operating and maintaining underground injection wells since 1953. This experience demonstrates that it is very important to locate wells where proper geology exists for ground water protection. The well construction features and materials are equally important. Well operation at this plant features a leak detection system that continuously monitors the mechanical integrity of the wells. The evaluation of these monitoring data provides early detection of problems before the environment can be harmed. Investigation and diagnostic techniques are then used to determine the nature and exact location of problems, whether they exist at the surface or downhole in the injection tubing, packer or casing. Once the problem is defined, remedial action is instituted. Finally the success of the repair is confirmed through additional testing.Only a limited number of repairs have been required over the past 33 years and all have been carried out without endangering the environment.
