Understanding the rock-fluid system (RFS) is critical for completion optimization. The RFS includes the rock, saturating fluids (both hydrocarbons and connate water), soluble minerals, and introduced completion fluids.

Fluid flow behavior and rock type are tightly coupled in unconventional reservoirs because of the high surface areas, very high capillary pressures, and complexity of both organic and mineral surfaces that exist in these complex pore structures.

Packages

Surface area and pore characterization
Gas sorption, mercury-injection capillary pressure (MICP), and cation-exchange capacity (CEC) measurements are used to characterize the surface area and pore structures of the rock.

Native fluids extraction and characterization
Services are offered to extract and characterize the native hydro-carbons in unconventional rocks. Characterization of composition and phase behavior at reservoir temperatures and pressures can be done in conjunction with Schlumberger Reservoir Laboratories.

Connate water characterization scaling potential, salt migration, and mineral dissolution
Unconventional reservoirs often contain vast quantities of salt and readily soluble minerals that can dissolve and diffuse into the introduced fracturing fluids. Their variety of salts and minerals can be fully characterized, and full flowback fluid analysis is available.
