The advance of hydraulic fracture application in longer, more extensive horizontal wells has further confounded the modeling techniques to estimate the impact these stimulation techniques incur on well production.
There is now a greater need to incorporate the complexities involved with geological, geomechanical, and flow considerations, not just from an in-situ point of view, but also taking into account how the reservoir system changes during hydraulic fracturing.
The incorporation of these disciplines only further magnifies the inconsistency across different conventional fracture models. The offering of hydraulic fracture modelling approaches in the Petrel platform covers an array of means to model the effect of hydraulic fracture stimulations.
Hydraulic fracture modeling in the Petrel platform covers a wide breadth of possibilities. These range from conventional planar fracture and calculated stimulated reservoir volume approaches, all the way to numerically simulated hydraulic fractures that are functions of not only hydraulic head, but also geomechanical and geological variability.
The Petrel RE core offers the ability to create hydraulic fractures as completion objects, which can be used to create planar hydraulic fractures or equivalent productivity index flow manipulations.
Incorporate effects of hydraulic fracture stimulation into simulation models
Hydraulic fracture modeling within the Petrel platform offers an additional level of flexibility more pointed at unconventional, multistage, planar fracture modeling, which gives reservoir engineers an intuitive user interface for incorporating the effects of hydraulic fracture stimulation into ECLIPSE or INTERSECT simulation models. Additionally, the stimulated reservoir volume (SRV) can be calculated from either pumping related information or microseismic to attribute the effect that the hydraulic fracture stages have on production.
Lastly, Kinetix Shale engineered stimulation design in the Petrel platform provides a seamless connection from geology and geomechanics into completion engineering, and reservoir engineering and production workflows.
This integrated workflow introduces new hydraulic fracture models. These models incorporate the 3D varying geologic model and natural fracture definition, to calculate how a hydraulic fracture will propagate fluid and proppant into the reservoir. This hydraulic fracture understanding is then translated into a reservoir-engineering focused model to estimate the effect on production.
