Schlumberger

Water Saturation and Movable Fluids

Interpreting all available petrophysics data and integrating these results with other measurements helps you gain a comprehensive understanding of your reservoir. Our experts have experience with all logging measurements—whether conveyed on wireline or drillpipe, pumped down through drillpipe or conveyed via tractor, and in openhole or cased hole environments.

MR Scanner

Obtain NMR measurement of porosity, permeability, and fluid volumes independent of the rock matrix.

CMR-Plus

Identify producible hydrocarbons in thin sands; low-contrast, low-resistivity pay; and carbonates by using high-resolution NMR.

Dielectric Scanner

Directly measure water volume and rock textural information in real time to accurately determine hydrocarbon volume, whether in carbonates, shaly or laminated sands, or heavy oil reservoirs.

proVISION Plus

Deliver accurate lithology-independent porosity and continuous permeability in real time.

Rt Scanner

Calculate vertical and horizontal resistivity from direct Rt Scanner triaxial induction measurements and solve for formation dip to account for anisotropy and thin beds.

Direct Measurement of
Water Volume and Salinity

Dielectric Scanner multifrequency dielectric dispersion service measured water-filled porosity of individual thin beds in Venezuela to determine high-quality reservoir zones.The proVISION Plus MR log helps characterize two additional laminated sand–shale sequences.Quality control of Schlumberger multimineral evaluation of LWD data shows error to be extremely low.Logging showed a highly laminated interval with net to gross 40% to 60% in the lower setion and 30% to 40% in the upper section. Porosity in the sand laminations is 30%.
