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 …

Data quality of well logs and laboratory measurements is crucial for accurate petrophysical
interpretations in formations with complex solid compositions, thin beds, and adverse …

Актуальность разработки методики оперативной оценки призабойной зоны пласта
(проницаемости призабойной зоны пласта и скин-фактора) обусловлена в первую …

The invasion of drilling mud filtrate into the formation is a commonly overlooked process. It is
generally considered only as a problem of well stability and logging environment. However …

Porosity is one of the key indices to characterize the pore structure of dense sandstone
reservoirs, and accurate prediction of porosity is important in reservoir evaluation. The …
