Optimizing Matrix Stimulation Treatments for Carbonate Completions
Includes a Live Event on 03/03/2020 at 9:30 AM (EST)
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. This webinar will start with a brief introduction to matrix acid stimulation in carbonates and describe typical design elements. This will be followed by design challenges, such as treatments in long heterogeneous intervals, in fractured reservoirs, and in mature reservoirs. 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. Pptimization 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 ensures that all variables are addressed systematically.
