Different geological structures require specific drilling approaches. For example, when drilling through gypsum layers:

• Pretest drilling fluid composition
• Use anti-gypsum treatment agents like soda ash calcium removal
• Employ viscosity reducers with strong calcium resistance
• Supplement with fluid loss reducers and anti-sloughing agents

Proper understanding of local geology is essential for optimal drilling performance and equipment longevity.
