Fracture Detection and Modelling – DNF & CFM
Fold-and Thrust Belt with fractured anticline reservoirs. Identifying fractures from seismic data, calibrating with well data, surface and regional data, and building a fracture model either as Discrete Fracture Model (DFM) or Continuous Fracture Model (CFM).
Problem:
Fractured carbonate reservoir field containing multiple wells and 3D seismic data. A new fracture model was required to better assist well panning and reservoir prediction.
Solution:
A number of clients asked ERCE to build either a Discrete Fracture Model (DFM) or Continuous Fracture Model (CFM). For these projects, ERCE carried out a comprehensive interpretation of the seismic data, together with detailed fault mapping and fracture identification. All data were integrated with petrophysical data, fractures from image logs, as well as production data.
A DFM or CFM was then constructed in close collaboration between our seismic interpreter, petrophysisist, structural geologist and engineers. CFM models are particular powerful as they allow a certain flexibly of the model that allows to integrate updates whenever new well data are acquired.
Benefit
The key to undertake such projects is a close cooperation between highly skilled team members. ERCE has expertise in seismic interpretation, structural geology, petrophysics, geomodelling and reservoir engineering. ERCE used a range of software like Kingdom Suite, Petrel, IP, and MOVE for this study.
