ABOUT STIM-LAB

Laboratory Testing

At Stim-Lab, we pride ourselves in providing answers, not just data.  Our experts have extensive experience in all areas of completion and stimulation, giving us the ability to fully evaluate your problem propose a meaningful testing regime.  In cases where the testing does not meet our standard offerings, we can design and manufacture testing equipment to give our customers answers to the question they are posing.

Research Consortia

Stim-Lab's research consortia offer the opportunity for companies to participate in multi-client studies that investigate subjects of broad industry interest. Every dollar you spend in support of one of our consortia will return hundreds of dollars worth of research.  Producers, service companies and suppliers in these consortia study a variety of issues including:

·         Proppant Conductivity and Fracture Cleanup Consortium

§          develops new methods to scientifically predict the cleanup of proppant packs within hydraulic fractures.  This data allows you to select fluids, proppants and production methods to optimize production

·         Matrix and Fracture Acidizing Consortium

§          investigates parameters associated with fracture acidizing, matrix acidizing, and foam diversion in vertical and horizontal wells.  The data obtained allows you to confidently select additives and treatment conditions to optimize stimulation results.

·         Screen Cleanup and Performance Evaluation Consortium

§          the only consortium in the petroleum industry that evaluates the performance of screens under a variety of downhole conditions using various large-scale flow cells.  The aim of the Screen Consortium is to develop criteria when a specific screen is selected for a particular formation.

Consulting and Treatment Simulation

Our consultants have thousands of hours of experience designing stimulation treatments and handle difficult cases on a daily basis.  If you are encountering a problem, chances are our experts have see something similar and will assist you in prompt resolution.

History

Founded in 1985, STIM-LAB, Inc. has become a recognized leader in oil and gas well completion testing and reservoir analysis. STIM-LAB operates two facilities including offices and a research center in Duncan, Oklahoma, and STIM-LAB Formation Damage, located in Aberdeen, Scotland.

Facilities

The Duncan Research Center is housed in a modern, fully equipped, 17,000 sq. ft. facility. Laboratory capabilities are in place to evaluate a variety of properties for drilling fluids, cementing and stimulation fluids under simulated reservoir conditions. In addition, our reservoir analysis group offers a wide range of geological, petrophysical and engineering services including log analysis, carbonate and clastic depositional environments, diagenesis, area studies and exploitation procedures.

With the opening of STIM-LAB Formation Damage, advanced completion testing and research services are available for North Sea and European operators.

Typical Studies

Typical engineering motivated studies include:

• Independent analysis of recommended completion fluids
• Testing of mud damage on reservoir samples
• Stepped flow rate testing to determine fines migration threshold
• Development of nondamaging or stimulating fluid formulation
• Determination of fracture conductivity with various proppant loads and types
• Visual large scale simulation of proppant transport and placement
• Examine cuttings for compatibility with completion fluids
• Describe waterflood susceptibility and flow units
• Scale analysis
• Formation specific acid reaction coefficients

Typical geological motivated studies include:

• Examine cuttings for mineralogy
• Explain log responses by lithologic characteristics
• Determine depositional and diagenetic controls on reservoir quality
• Relate logs to cores to extend log interpretation through the reservoir
• Identify and quantify porosity classes in reservoir
• Find statistical relationships between rock properties and log responses
• Measure FRF, m, n, a, CEC etc. for log analysis

Consortia

Completion research is a vital and ongoing effort at STIM-LAB. Five research consortia, sponsored by STIM-LAB, study Proppant Conductivity, Rheology and Proppant Transport, Acidizing, Screen Cleanup and Casing Cleanup. Consortium members jointly select research topics and benefit from interaction and leveraging of efforts. As a result of this research, STIM-LAB is constantly developing new and innovative completion techniques, equipment and data.
