... considered is hole cleaning. Hole cleaning is a challenging task even for a single phase drilling fluid. Moreover, there is still a lack of information how the cuttings are transported when gas-liquid mixtures are used as drilling fluids. Flow rate optimization during UBD operations for liquid and gas phases...

..., in a previous paper1, depletion experiments on laboratory-scale cores using a one-dimensional model at the Darcy scale, describing the multiphase flow of oil and gas. In this paper we analyse a mechanism of gas phase flow based on the geometry of the bubbles and its consequences on their motion. Actually some...

... Abstract The paper presents an extension of a theoretical and numerical model that the authors have developed previously to address sand production as an erosion problem coupled with hydro- and geo-mechanical effects. A gas phase contribution is added to the governing equations within...

... temperature and pressure conditions are such that the injected acid gas phase is a supercritical fluid that is miscible with the existing reservoir fluids and, thus, the potential for adverse relative permeability effects (due to the creation of in-situ immiscible liquid and vapor phases) is avoided. In other...

... is achieved primarily because the gas phase is dispersed into bubbles, which are generally about the size of the pore channels (2) . Additionally, flowing lamellae encounter significant drag because of the presence of pore walls and constrictions (3) . This performance makes foams suitable for three potential...

The sorption model accounts the non-ideality of the free gas phase as partial fugacity of the gas component is calculated using the Peng-Robinson equation of state.

The results indicate that the field performance can be predicted by assigning low gas phase relative permeability...
