New diversion service for shale-fracturing operations

The new StimMORE fluid diversion service diverts fracture treatments along a wellbore in cemented or openhole completions. The service is especially suited for use in shale formations.

Used in combination with the StimMAP LIVE hydraulic fracture stimulation diagnostics service, which delivers microseismic data while the fracture treatment is pumped, the StimMORE service allows real-time optimization of fracture treatments.

StimMORE can be used in most well geometries and is suited to horizontal wellbores, cased hole and open hole, up to a maximum temperature of 121° C.

The diversion slurries can be pumped on the fly as part of the main treating fluid, diverting the fracture as needed based on the real-time integration of microseismic data. The slurries are based on standard fracturing fluids and proppants, with the addition of a proprietary mix of materials that enable fracture diversion.

The StimMORE service is part of the Contact portfolio of staged fracturing and completion services. These technologies allow the company to create complex drainage patterns within the reservoir that enable access to reserves that may have otherwise been left in place.

The StimMORE refracturing treatment was recently applied to one operator’s horizontal well in the Barnett shale. Initial gas production of 2.2 MMcfd had declined to less than 500 Mcfd during a 4-year period. The StimMORE service, coupled with the StimMAP LIVE real-time fracture monitoring service, enabled efficient and cost-effective coverage of previously unstimulated well sections, resulting in a net increase in estimated ultimate recovery of 0.7 bcf, the company notes.

New data management tool supports exploration uses

TIGRESS Live!, a new data management tool, supports the entire exploration life cycle with an integrated, real-time framework.

The firm says the tool offers a more streamlined approach for managing capital and expertise in locating and producing hydrocarbons in the shortest time possible.

The software sifts data from available sources, such as existing physical and digital archives, interpretation systems, and geostreaming services, and loads it via this firm’s drop box technology. Production reporting, well performance, and analysis data are available, updated, and distributed in real time.

The software comes with its own feature-rich tools covering all aspects of the exploration process from seismic survey through geology, petrophysics, and mapping, to production and reservoir engineering.
