Improving the damaging effects of drilling fluids using silica fibers

Abstract: Fracture reservoirs account for a large part of reservoirs throughout the world. A reservoir consisting of a network of fractures is called Fractured Reservoir. Fractures’ characteristics also depend on the kind of their production process. Fractures can have positive and negative effects on the drilling fluid. Presence of extensive fractures and the dual medium nature of these reservoirs add to their complexity in a way that conventional methods of evaluating the performance of reservoirs do not yield satisfactory results. Numerous experiments show that drilling fluids cause severe and irreversible damages to the fractures and lead to a significant reduction in the rate of exploitation from hydrocarbon reservoirs. The main objective of this project is to study the effect of fiber additives used in the drilling fluid is to reduce damage to the fractured reservoir. In this paper, the silica fibers have been used in the drilling fluid. These data are based on existing machines and limited availability have been achieved. It should be noted that these results do not hold for all situations and every case should be studied individually.
