GeoROX provides detailed chemical and mineralogy rock characterization on drill cuttings and core chips. A combination of X-Ray Fluorescence (XRF) analysis and X-Ray Diffractometry (XRD) measurements are obtained in near real-time at the well site. All key chemical, mineralogy, and geomechanical information are delivered within 1-2 hours of drilling through a formation.
A combination of long wait times for lab results and the costs associated with them can slow down exploration and development phases of a program.
GeoROX on-site geochemical analysis provides an ideal solution to these problems. Examining drill cutting samples at the wellsite enables operators to make time-sensitive decisions such as choosing correct casing points and coring intervals. This powerful information coupled with GeoSource service combine to create a full geochemical analysis solution onsite.
Deploying GeoROX service using fit for purpose equipment that is capable of measuring the chemical elements and mineralogy at the well site allows immediate results. Analysis can be used to make critical decisions for landing horizontal wells.
GeoROX is suitable for exploration, appraisal, and development projects where having early geochemical data is used for evaluation and rapid decision making. The service can be deployed as a complete standalone solution to mud logging services or integrated with other GEOLOG services.
GeoROX is ideal for unconventional plays, however it has proven to be very effective in all reservoir types where geochemistry can aid in formation evaluation.
Applicable for all drilling environments from remote land operations to ultra-deepwater, and not affected by any specific drilling techniques.
In this example, GeoROX was utilized to help geosteering a well through a relatively homogeneous sandstone sequence. The presence of faults dislocated the target, and the identification of specific chemical markers with GeoROX helped not only to identify the faulted zones but also isolating them in the production string to optimize overall production.
