Paper presented at the SPE European Formation Damage Conference & Exhibition, June 5–7, 2013
Paper Number: SPE-165108-MS
... the modeling predictions with field and laboratory data to identify probable causes for increasing skins and declining productivity index (PI) values observed in some of the wells under investigation. It discusses the results of an experiment designed to simultaneously assess the effects of pressure depletion...

... combination of drawdown and depletion and stay within its design limits except in rocks with a very low friction angle, where excessive deformation was possible. To ensure against use of the technology in an unsuitable formation, every proposed application is screened using either an analytical or FEA...

... to characterize the matrix and the fracture sub-systems separately and to continually optimize the characterization process throughout the production phase to accommodate pressure depletion effects on production. Laboratory experiments were performed on a Clashach core sample with a simulated single fracture...

Paper Number: SPE-94527-MS
... failure on permeability for a weak sandstone. A yield zone model was used to determine the depth of rock failure away from the wellbore and the effective stresses in the yield (failed) zone. The permeability changes were coupled with the yield zone model to predict the evolution of skin during depletion...

Paper presented at the SPE European Formation Damage Conference, May 21–22, 2001
Paper Number: SPE-68981-MS
... quantification of the apparent viscosity of polymers in porous media. Past experimental and theoretical studies have shown that, in the absence of adsorption, the viscosity of polymer solutions decreases in porous media due to polymer depletion near pore walls. The proposed models considered pores...

... of realistic formation stresses and radial fluid flow. The increase of the drawdown and depletion, by raising the effective external stresses and the pore pressure gradient, to conditions by far exceeding the formation collapse stress, resulted in productivity reductions. The differential fluid pressure over...
