Shale Resource Evaluation

Shale Resource Evaluation


Shale Resource Evaluations have become one of the top INEXS core competencies over the recent decade. The INEXS evaluation includes:

  • Complete regional geological study based on the correlation of regional deep well logs. Capture top, base, and isopach values, and identify top and bottom seal, stratigraphic variations, and stratigraphic sub-units.
  • Generate a full lab analysis including geochemistry, organic petrology, rock mechanics, lithology, thermal maturity (VR), organic richness (TOC), kerogen type, geomechanics, and brittleness.
    Integrate all geological, geomechanical and lab data.  Generate regional geologic maps including depth structure, isopach, isochore and gas in place maps.
  • Integrate a grid of 3D seismic data and available reprocessed 2D seismic data, connecting as many recent wells as possible.Reprocessing of the 3D seismic data would improve higher frequencies, reduce noise, and create better gathers for pre-stack analysis.  Next generate a series of seismic derivative attributes including AVO, seismic inversion, Poisson’s ratio, Young’s modulus, lambda rho, mu rho, etc.
  • Create regional permitting, drilling, and completion activity maps including posting all key wells used for lab analysis.Create detailed database of practical IP (30-day average), cumulative production, and any available information on perfs, frac stages, etc.
  • Generate a series of cross-correlation attributes – some examples would include TOC vs. isopach, or VR vs. depth, practical IP vs. Poisson’s ratio, Young’s modulus vs cumulative production.
  • The project will be delivered in digital format for further analysis by the client in formats compatible with Landmark, SMT, SeisWare, Petra, and Transform.

In addition, activity updates will be offered every six months to integrate newly released wells, updated production information, and possibly integrate additional 2D seismic data.
