Non-Matrix Quick Pass: A Rapid Evaluation Method for Natural Fractures and Karst Features in Core

Mechanical and chemical processes experienced by carbonate rocks result in a complex network of natural fractures dissolution features that have direct implications on porosity, permeability, connectivity reservoirs. Characterization is best done core; however, it can be time-consuming due to the large amounts individual present long list attributes typically collected for each feature. Additionally, karst core, such as vugs small cavities, are seldom characterized quantitative way or overlooked. We introduce new methodology, called non-matrix quick pass (NMQP), which allows collection rapid yet fashion at rate 12 20 m core per hour. The NMQP methodology offers enough vertical resolution so observations integrated with other wellbore data types (e.g., wireline logs, well tests, production logs). This method also yields estimates density porosity rigorous provide technical basis build first-generation dual-porosity models describing component reservoir its potential impact field performance.
