Petrophysical interpretation of borehole geophysical measurements in the presence of deep mud-filtrate invasion remains a challenge in formation evaluation. Traditional interpretation …
Mud-filtrate invasion displaces in-situ formation fluids away from the wellbore in porous and permeable rocks. In the presence of water-base mud (WBM), invasion is accompanied by …
Several physics-based and empirical models have been developed in the past to estimate permeability from well logs. Estimation of flow-related petrophysical properties from …
Petrophysical interpretation of logging-while-drilling (LWD) borehole measurements in the presence of electrical anisotropy, mud-filtrate invasion, noise, and well deviation effects …
Formation pressure/fluid measurements are impacted by mud-filtrate invasion, which may require long fluid pumpout durations to acquire hydrocarbon samples with minimal mud …
Well logs are geophysical measurements of rock properties acquired continuously along a borehole. Because of the physics underlying their operation, borehole logging instruments …
Reliable assessment of in situ storage and flow properties of rocks from borehole geophysical measurements and core data is crucial for appraising subsurface fluid …
A critical component of Formation Evaluation is the estimation of in situ petrophysical properties and solid/fluid composition of rocks from multiple well logs and core laboratory …
Data quality of well logs and laboratory measurements is crucial for accurate petrophysical interpretations in formations with complex solid compositions, thin beds, and adverse …
