Enhanced recovery
This paper presents a case study of a tool-free fishbone fracture stimulation technology using sand jetting and acidizing in openhole wells, providing a technical solution for low-permeability and complex-lithology carbonate reservoirs in the Middle East.
The industry clearly needs creative solutions that are affordable and operationally flexible, and the three papers selected for this Technology Focus highlight some innovative approaches that aim to unlock those extra barrels.
