摘要： A method and apparatus for converting downhole wireline logging measurements of pressure gradient, formation pressure and temperature into estimates of petroleum fluid PVT properties unaffected by oil-based drilling mud, without the need for retrieving actual petroleum samples from the borehole for laboratory analysis at the surface. The statistical accuracy of the PVT properties of reservoir fluids are enhanced with geochemical information of the fluids expected from a given reservoir.
