A Complete Range of Geological Services

SCAL, Inc. provides determination of lithology, diagenesis, diagenetic sequence and reservoir properties through geological description, analysis and thin section petrography of conventional core, drilled sidewall cores and cuttings. Integration with XRD and SEM analysis furnishes an operationally focused reservoir characterization. The integration of geological studies with routine and special core analysis renders a robust representation of the present reservoir character, calibration of wireline log response and the potential for drilling, completion or production formation damage.

This integration simultaneously documents rock fabric, thereby, permitting reconstruction of the depositional setting and diagenetic history. Visualization of the original depositional environment and diagenetic overprint are critical to development and testing of predictive models for oil and gas exploration.

Surveying Gamma-Ray Spectrometer

The handheld GR-130 miniSPEC allows the user to detect radioactive material and aut omatically identify the presence of radioactive nuclides.
