Stim-Lab offers a broad range of testing services to meet the needs of today's expanding
coal gas industry. In order to optimize gas production, it is important to accurately
characterize each reservoir fully and examine coal fluid interactions prior to completing
a well. Stim-Lab tests are designed to simulate the unique conditions found in coal
seams. Tests and studies available from Stim-Lab include:
- Coal reservoir characterization
- Coal and rock mechanical properties
- Coal core flow tests
- Rheology and proppant transport studies
- Fluid leakoff and fracture conductivity
- Coal stimulation simulations
Utilizing information generated in the laboratory, stimulation treatment design
programs and production simulators can be used to predict the production response
from a well or field following a proposed stimulation.
On-Site Assistance
Stim-Lab also provides extensive on-site assistance including:
- Fracture treatment design
- Pre-treatment planning>
- Mini-frac design and analysis
- Treatment quality control
- Treating-pressure analysis
- Post-stimulation evaluation
These services are supported by a variety of engineering programs installed on notebook
computers for use on location.
Research
In conducting Gas Research Institute (GRI) supported research, Stim-Lab is evaluating
and assisting in designing advanced hydraulic fractures for coal seams. Research
has shown that many fractures created in the Black Warrior Basin of Alabama are
providing production rates well below their potential. Re-fracs on several GRI/Taurus
Rock Creek Research Site wells utilizing fracturing fluids and completions designed
by Stim-Lab have shown a three to four fold increase in gas production over the
original completions. Stim-Lab has evaluated a large number of additives that are
normally used in coalbed methane stimulation treatments to help select optimum completion
fluid formulations and minimize potential adverse coal interactions.
