simulation of formation damage due to chemical precipitation

📄 Project Abstract

Formation damage refers to the impairment of the permeability of petroleum bearing formations by various adverse processes. Formation damage is an undesirable operational and economic problem that can occur in many phases of field development including drilling, completion, workover, production, stimulation, waterflooding and enhanced oil recovery. In fact, it is among the major causes of a well productivity reduction in petroleum reservoir. Proper understanding of the factors causing these damages is therefore of utmost important. Formation damage indicators include permeability impairment, skin damage and decrease of well performance. Formation damage can be caused by factor such as fine particle transportation in porous media. Fines enter the formation as suspensions during drilling and completion operations. They can also be generated due to fluid-fluid and fluid-rock interactions. When they enter the formation, they get entrapped in the pore openings, fill and plug the pore spaces...
