In this paper, we present a workflow that allows for accurate well and completion performance simulations to be conducted automatically. A number of innovative technologies are introduced to enable this workflow. First, a mesh generator was developed to automatically construct high quality, near-well meshes for wells with different deviation angles and variable producing segments. Second, the enriched finite element method, a new numerical technique, was used to provide detailed modeling of geological features (such as horizons, natural fractures, and no-flow boundaries) and completion characteristics (such as fractured completions and perforations) without having to manually construct a mesh that honors these complex geometries in detail. Third, a procedure was developed to fully couple the completion hydraulics and the near-well porous media flows.To demonstrate the effectiveness of the new technologies, three application examples will be detailed: (1) a sensitivity analysis of partial completion or stimulation on well performance; (2) an evaluation of the productivity of a new sand control device that uses MazeFlo TM screen technology and contains a multitude of segmented production zones; and (3) the design of a multiply-fractured completion. Throughout these examples, guidelines on maximizing the efficiency of completed segment, stimulated well length, or fractured completion are summarized.

“…More recently, fine-scale simulations have been reported to more accurately characterize complex completions (Byrne et al, 2009;Kline et al, 2006). However, such well performance analyses usually require detailed numerical models to analyze flows within the completion as well as in the near-well region.…”

A New Enriched Finite Element Method to Simulate Hydrocarbon Reservoirs Containing Subsurface Features

et al. 2009

In this paper, we present a new computational framework to simulate reservoirs containing complicated geological and engineering features (for example, faults, induced or natural fractures, and perforations). Unlike traditional computational methods, the new approach does not require the mesh to honor the geometrical shapes of subsurface features. The effects of these features on the solution are captured by enriching the finite element approximation based on the Partition of Unity theory.This new simulation capability eliminates the laborious meshing work traditionally required for modeling complicated subsurface features without compromising solution accuracy. It is especially useful in the detailed analysis of near-well physics where subsurface features at this scale need to be modeled both accurately and efficiently. In cases where the subsurface features are evolving, the computational mesh does not have to know a priori the shape of the evolving subsurface features. This method is particularly useful in the study of curvature changes of hydraulic fractures due to evolving stress fields away from the well.A number of examples are given to demonstrate the effectiveness of the proposed approach. The examples are grouped into three broader application areas: (1) well performance analysis of fractured completions, (2) deformation characteristics of reservoirs containing fracture networks, and (3) simulation of fracture interference and re-orientation.

“…The new modeling capability allows for detailed yet fast analysis of flows in near-well region and hence provides a means to quickly evaluate the well performance of various completion or stimulation options [13,17]. The new numerical method can also be coupled with geomechanics models and answer questions related to (1) the operability of wells drilled through complicated subsurface features or (2) the injectivity of a well in complicated geological conditions.…”

On the use of enriched finite element method to model subsurface features in porous media flow problems

et al. 2011

View full text Add to dashboard Cite

In this paper, a new enrichment scheme is proposed to model fractures and other conduits in porous media flow problems. Inserting this scheme into a partition of unity based method results in a new numerical method that does not require the mesh to honor the specific geometry of these subsurface features. The new scheme involves a specially designed integration procedure and enrichment functions, which can capture effects of local heterogeneity introduced by subsurface features on the pressure solution. The new method is also capable of modeling fractures with low as well as high conductivity. Another feature of the proposed scheme is that, even though two enrichment functions are used to model the permeability change at the two rock/fracture interfaces of a fracture, only one element partition is made for numerical integration. To demonstrate the accuracy and effectiveness of the proposed approach, production problems for wells that were stimulated or completed by longitudinal fracture, transverse fractures, and perforations are studied.
