The paper presents an Averaged Drift-Flux Model (ADFM) facilitating consideration of the internal structure of the gas-liquid slug flow in a vertical pipe. Modulation equations are used for flow parameter averaging. The allowable domain of the ADFM h

One of the main problems of managed pressure drilling (MPD) is detection and monitoring of gas kicks from the formation to the annulus. The model is proposed to estimate the parameters of the gas kick and gas-liquid flow in a well during MPD process

The paper presents a model of nonstationary liquid-gas flow in a well considering non-equilibrium phase transitions. The problem is topical for Managed Pressure Drilling (MPD) with lightweight oil-based mud in case of a gas kick. The model accounts f

A model and a method of dynamic analysis of a drilling system with a Positive Displacement Motor (PDM) have been proposed. The relevance of the work is related to the need to consider the interaction of the models of the drillstring oscillations, wel

Slips, slip elevators, spiders, etc. have been widely used as oilfield service tools to grip and hold drill pipe, drill collars and casings by acting as a wedge. A pipe in a slip with a conical bearing surface is subjected to complex loads comprised

Summary A dynamic stiff-string torque-and-drag (T&D) model is presented that assumes steady-state motion of the drillstring as its basis for calculations. Results are compared with previously published T&D models that are based on static equilibrium.

Bent-housing positive displacement motors (PDM) keep the leading position among tools for drilling directional wells. The efficiency of drilling deviated wells can be greatly enhanced by the method of Targeted Bit Speed (TBS). This method enables wel
