Abstract

Systems, methods, and computer-readable media are provided for a near-well unstructured grid model builder for generating a full-field unstructured grid for reservoir simulation. As described further below, the near-well unstructured grid model builder may include a workflow interface and a parallel unstructured grid model builder. The inputs to the near-well unstructured grid model builder may include existing well trajectory and completion data, future well data, a geological model, a structured grid simulation model, or any combination thereof. The near-well unstructured grid model builder may output a near-well unstructured grid having a specified grid resolution in regions of interest that include a well.

First claim

What is claimed is:

1 . A non-transitory tangible computer-readable storage medium having executable computer code stored thereon for a workflow interface for generating a near-well unstructured grid, the computer code comprising a set of instructions that causes one or more processors to perform the following:
define a workflow interface for a near-well unstructured grid builder, the workflow interface configured to:
define input data for the near-well unstructured grid builder;
define gridding options for the near-well unstructured grid builder;
display well data of the input data in a 2D or 3D visualization;
provide well data and a region of interest within the input data to an unstructured grid model builder for generation of an unstructured grid.
display geometry of the generated unstructured grid;
display the properties of the generated unstructured grid; and
display the perforation of the generated unstructured grid.

2 . The non-transitory tangible computer-readable storage medium of claim 1 , the workflow interface comprising a graphical user interface.

3 . The non-transitory tangible computer-readable storage medium of claim 1 , the workflow interface configured to well data of the input data in a 2D or 3D visualization according to user-selected colors.

4 . The non-transitory tangible computer-readable storage medium of claim 1 , the workflow interface configured to well data of the input data in a 2D or 3D visualization according to user-selected colors.
