Abstract
Systems and methods for dynamically developing a wellbore plan with a reservoir simulator. The systems and methods develop a plan for multiple wellbores with a reservoir simulator based on actual and potential reservoir performance.
Claims28
A computer implemented method for developing wellbore plans with a reservoir simulator, comprising:
- identifying connected grid cells in a gridded reservoir model that meet a preselected filter range criteria comprising reservoir performance values;
- creating a drainable volume indicator for each group of connected grid cells that meet the pre-selected filter range criteria by eliminating connected grid cells within each group of connected grid cells that do not meet a minimum predetermined permeability and mobile oil fraction within a specified radius;
- calculating an adjustment value on a computer system for each drainable volume identified by each drainable volume indicator;
- selecting each drainable volume that has an adjustment value up to a predetermined maximum adjustment value and designating each selected drainable volume as a completion interval grid;
- and
- connecting contiguous completion interval grids on the computer system to form one or more completion intervals.
A non-transitory program carrier device carrying computer executable instructions for developing wellbore plans with a reservoir simulator, the instructions being executable to implement:
- identifying connected grid cells in a gridded reservoir model that meet a preselected filter range criteria comprising reservoir performance values;
- creating a drainable volume indicator for each group of connected grid cells that meet the pre-selected filter range criteria by eliminating connected grid cells within each group of connected grid cells that do not meet a minimum predetermined permeability and mobile oil fraction within a specified radius;
- calculating an adjustment value for each drainable volume identified by each drainable volume indicator;
- selecting each drainable volume that has an adjustment value up to a predetermined maximum adjustment value and designating each selected drainable volume as a completion interval grid;
- and
- connecting contiguous completion interval grids to form one or more completion intervals.
A computer implemented method for validating wellbore plans for new wells, comprising:
- running a reservoir simulator for each new well over a time window;
- calculating a constraint value on a computer system for each new well;
- selecting a filter range criteria;
- eliminating each new well with a constraint value outside the filter range criteria;
- ranking each new well that is not eliminated using the computer system according to a drainable connected oil in place and a difference between a maximum oil rate and a deltaPressure, using a weight factor;
- and
- selecting a best new well from the ranked new wells.
