Paper Number: SPE-125955-MS
... permeability, by creating large flow channels (wormholes) and dissolving formation rock. Therefore, acid placement in the targeted zones is of critical importance. In most producers the reservoir is of non-homogeneous nature, so it is common to find perforated intervals in zones with different permeability...

... to 1,500 ft of perforated intervals producing together from different layers. Stimulation treatments in the area historically have been performed using 7.5% HCl pumped through coiled tubing and using foam diversion. In 2008 a different approach was taken to stimulate producing zones across this...

... wellbore can prevent them from providing complete coverage over the entire perforated interval. A novel water-based consolidation system has been successfully developed to overcome safety, fluid compatibility, and placement issues, which most current solvent-based resins encounter during their field...

Data from production logs from several of the treated wells will be presented, which show excellent oil production distribution along the perforated intervals. In addition, production logs will also be shown for wells acidized with other diverters, such as foams...

... perforated intervals spanning 180 ft and 269 ft, respectively. Hence, adequate diversion of acid into the desired zones was a technical challenge. In addition, the crude oil was heavy (17 to 21°API), and compatibility with the stimulation fluids was a concern. In this paper, we demonstrate the fluid...

Combining this with the properties of a viscoelastic diverting acid will significantly increase fracture conductivity as well as the effective stimulation of all perforated intervals. The fluids were combined by using a pumping technique that consists of...
