Abstract

Drag reducing agents (DRA) has been used to inject the produced water into the producing reservoir and to inject produced water into an abandoned reservoir or aquifer. By introducing DRA into water injection well, the differential pressure drop in the water injection tubing is reduced thereby increasing water injection capacity. However, DRA is also suspected to bring about some damage on the reservoir and there are very less study being conducted to look into the effect of DRA on the formation, especially the near wellbore zone. This project will be looking more into the matter by evaluating the effect of commercial drag reducing agents on water injection well. This project will utilize the coreflooding technique and low range of core permeability around 30md and below will be used. The test will be conducted at standard temperature using a polymer type DRA.A fix concentration of 50ppm will be used for the DRA and the solution is to be mechanically degraded under high shear rates before injected into the core to simulate field situation. Different injection rate which will be 1cc/min and 5 cc/min and commercial drag reducing agents will be used to test their relationship with reduced permeability. Reverse flow will be conducted to restore the permeability.
