Identifying and evaluating a hydrocarbon accumulation in the subsurface is achieved through a complex team work, based on the combination of multiple disciplines such as geology, geo-modeling and geo-statistics, geophysics, reservoir engineering and economics.

The goal of the cooperation among several expertise is to identify areas where hydrocarbon accumulations can be present in the subsurface, to correctly evaluate these volumes, the relevant Probability of Success (POS), to define the final well location and to eventually evaluate the economics of the project.

ENGIE E&P uses an effective hydrocarbons exploration workflow based on a clear business strategy and on a series of well-defined actions.

To continuously increase performance of existing workflows, ENGIE E&P has been participating for more than 15 years in the development and optimization of methodologies and tools thanks to 100 external annual partnerships including O&G majors, world-class research institutes, universities and selected start-ups.

An example of cooperation DIONISOS tool for Sedimentological modeling
DIONISOS (developed in conjunction with IFPen,French public-sector research, innovation and training center active in the fields of energy, transport and the environment) develops models of interactions between factors that determine the final quality of source rock and the rock’s organic matter content. IFPen is the first in the world to create 3D models of these kinds of deposits. DIONISOS software can be used to locate “good” source rock with great accuracy using paleo-shorelines and model source rock characteristics so that users can be more selective in choosing exploration permits and focus on areas with the best features.

Subsurface geology and its related disciplines are important components of oil and gas industry exploration and production. This is especially true for ENGIE E&P, as our E&P activity is focused in challenging geologic environments, both conventional and unconventional. In mature areas, new hydrocarbon discoveries tend to be more structurally complex and located in tighter rock, at greater depths or in deeper water. Large-scale models define the concepts of regional deformation, which in turn influences subsidence history, basin modelling and maturation studies. Semi-regional and local structural studies are necessary to understand fault geometry, timing, migration pathways and hydrocarbon traps.

A complete structural analysis includes interpretation of seismic data, geodynamic modelling, fault analysis down to micro-scale. Analyses allow to construct realistic conceptual models in order to unravel structural development both in time and space. In turn, a model of the tectonic history of a basin provides a regional framework for understanding the development of essential elements and processes of the petroleum systems in a basin.

The development of advanced technologies for the study of the subsurface is key in ENGIE E&P. A strong commitment to technological innovation in structural geology, geomechanics, basin analysis and petrophysics makes us extremely competitive in hydrocarbon exploration. To reduce the number of exploration wells, optimize costs and the impact on the surface, ENGIE E&P has developed an integrated and multi-disciplinary approach aimed to improve the accuracy of subsurface investigation techniques. In addition, we are developing and using cutting edge technologies, through a strong cooperation with international research centers and universities.

Reduction of uncertainties
Geo-modeling is becoming essential to model reservoirs in order to take into account their increasing complexity. This science is evolving very rapidly and new concepts and new tools are emerging. The geo-models remain the essential link between the geologist and the reservoir engineer and are improved with the help of new mathematical and geostatistical tools and software.

ENGIE E&P makes use of the latest technologies for seismic interpretation and participates in their ultimate developments.

  • as an example, ENGIE E&P was involved at the very start of PaleoScan® technology by start-up named ELIIS, an interpretation tool that works in all time/depth/geological domains and enables quick interpretation of structural traps and delineation of reservoir bodies/seal properties.

  • Channel system tracked and analyzed through PaleoScan® (plus geologic map and well display)

  • ENGIE E&P is equipped with pre-stack analysis and interpretation software such as DUG or Hampson Russell tools, leading to correct identification of fluids in seismic AVO anomalies.
  • ENGIE E&P is an active partner of SAAM consortium (from Rose&Associates), where risks of amplitude-driven prospects are evaluated, analyzed, ranked.

  • Design and supervise right through a field’s life cycle
    Design of well architecture and supervision of drilling operations starts with exploration and continues right through the cycle of a field until its end of life when supervision is key. Throughout the process our drilling and petroleum engineers work with geologists and reservoir engineers to optimize production.
