Research Summary


* Smart Oilfield Technologies
* Naturally Fractured Reservoirs
* Pressure Transient Modeling
* Reservoir Characterization and Compartmentalized Systems

Production Geology
Simulations of transport processes in complex geological structure require detailed microlamination studies and inter-flow unit characterization. Synergistic approaches to combine signals from pressure transients and performance data for correlation of geological markers are being developed. Heterogeneities in subterranean reservoirs associated with faults need to be characterized. Multiple interference tests can potentially provide a significant insight into lateral and vertical communications. Predictive models are being developed to examine the impact of fault zones in terms of their transmissivities on pressure transient tests. Various conceptual models should be scrutinized to minimize the non-uniqueness of the predictive process.

Fractured Reservoirs
Multi-phase flow and pressure transient response characteristics of complex fractured rocks are being investigated. Improvements for scale-up processes of laboratory-derived pseudo-properties to large scale networks of fracture are being developed. Process related recovery issues are examined for systems exhibiting multiple porosity behaviors. Interporosity characteristics of tight rocks are being examined for various system properties. Predictive techniques are being developed for recovery processes in fractured systems under the influence of steam, solvent, and low tension floods.

Well Productivity Improvement
Studies are underway to develop effective methods for augmenting lift mechanisms in low pressure reservoirs. Initial studies are focused on low pressure gas reservoirs as affected by liquid loading.

Integrated Asset Mangement
Collaborative studies are underway addressing the issues related to data mining of massive data from continuously recorded sensors, asset component definition and diagnostics for detection of reservoir flow units.
