The initial objective of this workover was to recomplete the well as a simultaneous injection and production well. This would be achieved by retrieving the current dual completion strings, drilling in a new 4-½” x 3-½” production string and a 2-⅞” gypsum injection string in a dual completion configuration.
Due to unforeseen circumstances regarding the condition of the 9 ⅝”, the objective of recompleting the well could not be achieved.
TR-7 was drilled in 1991 and completed with a dual completion, 2x 3 ½” tubing inside a 9 5/8” casing. The snubbing operation was performed in July 2020 and lasted for 39days. The removal of the 3 ½” dual completion went as per plan. However on the mill run, to mill out the remaining tubings in the bottom of the casing an obstruction for the 8 ½”mill above the tubings was found inside the casing. After wireline evaluations the operations were suspended to evaluate the future use of the well.
