APPLICATION Fiberglass Tubing successfully repairs corroded 4 1/2" steel casing
LOCATION Near Eagle Pass, Texas
PRODUCT 2 7/8" 2500 psi Tubing, Threaded and Coupled with special O.D. Turned Down Collars
QUANTITY 42 Wells completed in 1991, 36 Wells completed in 1992
SERVICE
CONDITIONS
Approximately 1300 to 1700 ft. ran top to bottom in each well.  Water Injection 1000 psi, Injection Temp. 85 deg. F, Bottom Hole Temp. 100 deg. F.  The pipe is sandblasted and cemented in place.  Inflatable packers used in first 42 wells, used two joints of steel on the bottom, the steel was perforated.  The 36 wells completed in 1992 were installed using a polished bore receptacle with a latch instead of an inflatable packer.  A special cement shoe was used on these 32 wells and the liner was stopped above the original perforations.  This saved the cost of two joints of steel tubing, perforating and acidizing.
