Exploitation of the transient events during and after shaped charge detonation is giving the industry new perforating methodologies. The result is cleaner perforations that increase production and improve operational efficiencies. At the same time, enhancements to technology for shaped charges are delivering deeper penetration and bigger entrance holes with less debris. Because of the variety of methods used in the industry, the API recently updated standardized testing procedures recommended for comparing charge performance.
Mapping fracture propagation using microseismic monitoring is now possible in real time. New procedures provide live feedback on fracture development and the effectiveness of diversion methods. Case studies from Argentina and from Arkansas and Texas, USA, demonstrate its benefits in shales and tight gas sands.
Dolomite reservoirs can be prolific producers, but they can also be difficult to understand. The mineral is metastable, and conditions that enhance dolomite porosity and permeability vary from one location to another. The processes that convert limestone to dolomite can enhance porosity or destroy it. Developing zones with the best reservoir potential requires oil companies to overcome the difficulties inherent in evaluating this complex mineral.
Software based on open programming design principlesenables developers and geoscientists to create new function-ality without modifying the source code. These principles provide oil and gas companies, software companies and educational institutions the ability to develop proprietary plug-ins for a popular reservoir modeling program.
