Oil and Gas Tight and Unconventional Reservoirs
Full-scale assessment and characterization of your hydrocarbon resources for optimized production efficiency and profitability.

Tight and unconventional reservoirs comprise a broad group of hydrocarbon resources, including shale gas, shale oil, and coal bed methane (CBM). Development and production of these reservoirs is a capital and labor-intensive enterprise due to their low porosity and permeability. The key to profitable development is to minimize unnecessary drilling and hydraulic stimulation operations and increase the efficiency of existing operations.
At SGS, we offer a range of services for the assessment and characterization of tight and unconventional reservoirs, providing you with the information required for optimized production efficiency and profitability.
In our workflow, we apply innovative laboratory solutions (e.g. QEMSCAN and nanoindentation) to determine the geochemical, mineralogical, and mechanical rock properties from a range of rock samples, including core and drill cuttings. The rock sample data are used to calibrate the petrophysical interpretation of wireline log data for reservoir characterization on the well scale. Subsequently, the well data are integrated with seismic data and used to drive seismic inversion techniques for characterization on the reservoir scale.
