Abstract
Summary
The use of oil-based mud (OBM) in exploration and production drilling has a number of significant advantages. High stability of characteristics over a wide range of temperatures and pressures allows drilling in complicated mining and geological conditions. However, the high affinity of OBM with reservoir hydrocarbons interferes with laboratory studies of core material and fluid samples. Incorrect interpretation of research results leads to incorrect determination of oil saturation intervals, type of fluid, organic matter transformation degree, etc. The report presents some possibilities of geochemical methods for minimizing the influence of technogenic OBM components on the analysis results.
