Paper presented at the SPE Nigeria Annual International Conference and Exhibition, August 2–4, 2021
Paper Number: SPE-207175-MS
... Abstract The results of computer simulations and laboratory tests have been applied at Porth field in Nigeria to achieve a successful perforation through a blast joint to access hydrocarbon behind pipe. Accessing hydrocarbons behind pipe in multizone completions can be difficult. The options...
