Comprehensive Assessment of Resin Systems as a Combined Solution for Well Integrity Challenge and Unwanted Fluid Shutoff in Carbonate Reservoirs
المؤلفون: Albertus RetnantoThe petroleum industry usually uses class G cement when it comes to cementing jobs. However, that was the only option before, and because of that many issues came with it. Indeed, in the Middle Eastern region as well as the rest of the world, wellbore integrity is always a reason for concern. If wellbore integrity is not guaranteed, then production or drilling operations would be done under very unsafer circumstances. Read More
