Geological Considerations
Different geological structures require specific drilling approaches. For example:
When drilling through gypsum layers, pretest drilling fluid and use anti-gypsum treatment agents like soda ash calcium removal and viscosity reducers. Supplement with fluid loss reducers and anti-sloughing agents to maintain drilling fluid stability.
