Want to get more gas and less water?

Desorption from core samples? From cuttings? Gas bumps during mudlogging? Fluid collection and decompression?
Other reservoir analysis techniques are available, but none can match the accuracy, speed, and cost enabled by GST-WellDog's technologies.
The most accurate data available
Because we directly analyze the molecular bonds of the gas present, and correct for varying fluid conditions, our technologies avoid false positives and interfering signals.
Because we analyze gas partial pressure directly, our technology provides a significant increase in accuracy over competing methods.
Don't rely on sparse data sets, or on reservoir data collected and analyzed ex situ. Call us today and get to know your reservoir, finally.

GST-WellDog's technologies are not conventional oilfield techniques force-fit into unconventional applications. Our technologies were developed specifically to address unconventional coalbed and shale gas challenges. With these technologies you can evaluate your reservoir quickly and inexpensively -- even after the well is completed and it's too late to take a core sample.
TopSide Solutions wellhead evaluation
Have a field that is producing water but no gas? Wondering how long this will go on? Want to avoid the cost and disruption of interrupting dewatering while you test? Our TopSide Solutions technology allows you to evaluate your reservoir without even pulling the pump and tubing. In just a few short hours, we can measure gas content and critical desorption pressure for a price that will make you smile.
Critical Gas Content downhole evaluation
Drilling a new area, step-outs or in-fills? Need to quickly and effectively test multiple zones in the same well? Want to evaluate your reservoir before you complete and produce your wells? Our downhole Critical Gas Content wireline service provides the most accurate critical desorption pressure and gas content available in just a few short hours.
Evaluating methane and carbon dioxide partial pressures in coalbed and shale reservoirs
GST-WellDog exploits a well-known thermodynamic equilibrium characteristic of coalbed and shale gas reservoirs in order to quickly provide key reservoir properties. By accessing the methane partial pressure of these reservoirs via the solution gas concentrations, we are able to gain a direct handle on the gas in your reservoir -- while avoiding the petrophysical heterogeneity that interferes with data integrity from core and chip desorption techniques.
