Dr. Murtaza Ziauddin, Matrix Stimulation Advisor, Schulmberger, will be presenting on "Matrix Stimulation Treatments in Carbonate Reservoirs: treatment Fluid Optimization".

Abstract: Matrix stimulation treatments in carbonates are generally considered to be low risk. Production increases from these treatments are routine and the "success" of these treatments are perceived to be high. However, many treatments realize only a small fraction of the true well potential. If a more rigorous evaluation criterion is used, many treatments would not be considered successful. The lecture will start with a brief introduction to matrix acid stimulation in carbonates. The many variables influencing the treatment design and the challenges in optimizing treatment design will be presented. Influence of rock type, treatment fluid type, and operating conditions will be discussed. Optimization of fluid volume and injection rate as well as scale-up of linear laboratory core flow experiments to field conditions of radial flow will be presented. A design workflow is proposed which can be used to systematically address the key variables.
