FAQs

What is the role of casing in oil production?

Casing plays a very important role in oil production. First, casing plays a key role in stabilizing the well, preventing contaminants and water from entering the oil flow, and preventing oil from leaching into groundwater. It protects well walls and isolates different geologic layers from hydraulic fracturing pressures, production pressures, and corrosion conditions. It ensures the safe and effective process of oil exploitation and production.

Why use production casing? Why is it important in drilling?

Production casing isolates the production zone and protects the structural integrity of the well. And control formation pressure in case of oil pipe leakage. During drilling, it is critical to isolate fresh water layers, prevent contamination, and maintain pressure levels that balance formation pore pressure and rupture pressure.

How to determine the depth of casing depth? How does the casing work?

Typically, casing depth is determined by fracturing pressure, well pore pressure, and core analysis. Casing and grout keep well openings open, protect well walls from collapse and different geological components, and prevent contaminated subsurface and surface water from entering the aquifer and mixing contaminants with the water.
