Geological Services

SCA has its roots in the geological sciences. We have written three world-class textbooks in the field of petroleum geology and have conducted projects in over 50 countries around the world. SCA’s staff has collectively screened, evaluated, and generated thousands of exploration and development prospects worldwide and has found billions of barrels of oil equivalent. We know what makes a good prospect and we know how to spot the key factors that can make or break a prospect.

Our geological exploration and development services include:


  • Prospect generation, screening and evaluation
  • Basin evaluation
  • Regional geologic studies
  • Trend Analysis
  • Worldwide mapping experience in various tectonic settings (extensional, compressional, strike-slip, diapiric)
