The paper suggests and investigates a problem statement of well-logging inverse problem that is based on the integral conductivity parameter to describe a geoelectric section. Approach was introduced for a layered cylindrical model with radially hete

It has been repeatedly noted in the literature that the physic-chemical properties of oil extracted at different stages of exploitation can vary significantly. We have investigated a modification of the Buckley — Leverett model (BL model) in our pr

The article deals with the modification of the Muskat — Leverett model, taking into account the dependence of oil viscosity on dynamic water saturation. We fulfill numerical analysis of the solutions structure and show the effect of viscosity chang

The paper presents the results of an investigation into drilling mud flow with cuttings in a vertical well. The drilling mud rheology was described with the Herschel-Bulkley model. The axial Reynolds number was around 1000, the flow regime changing t

The effect of temperature on nuclear magnetic resonance (NMR) logging while drilling (LWD) has been studied. Heat conduction and permeability effects in the near wellbore invasion zone have been taken into account. Analytical solutions and numerical

An Eulerian mixture model of the two-phase flow was used for cuttings transport simulation. The model was tested using experimental data for particles transport in pipes. Three types of problem statements were analyzed: steady-state flow, non-station
