Drilling
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.
This paper presents a case study of oriented tubing-conveyed perforation followed by an acidizing operation to overcome technical challenges posed by a depleted reservoir targeted for a carbon capture, utilization, and storage project.
This paper details a trial involving the deployment of a transportable coiled tubing (CT) unit capable of holding 30,000 ft of high-strength 2⅞-in. CT.
