SPEI - Unconventional Reservoir Production
Description
Introduction -- Brief Review of Unique U. Reservoir Properties Affecting PDA
- Pore structure and gas storage mechanisms
- Material balance
- Flow mechanisms: matrix and fracture flow
- Non-static permeability
- Multi-phase flow
Brief Review of UR Completion/Stimulation Methods Impacting PDA
- Cavity completed wells
- Vertical, hydraulically fractured wells
- Horizontal wells, naturally completed, and multi-laterals
- Multi-fractured horizontal wells
Rate-Transient Signatures
- Introduction to Concept
- Example Signatures of:
- Vertical wells in low-k single porosity reservoirs
- Horizontal wells in low-k single-porosity reservoirs
- Multi-fractured hz wells in low-k single porosity reservoirs
- Multi-fractured hz wells in low-k double-porosity reservoirs
Analytical Methods for Rate-Transient Analysis
- Overview of Techniques
- Type-Curve Methods
- Modification of pseudo-variables to account for unique UR properties
- Example type-curve sets and application
- Straight-line (flow-regime) Methods
- Transient flow (bilinear, linear, elliptical and radial flow)
- Boundary-dominated flow (FMB)
- Simulation
- Some tips on model setup, history-matching and integration with RTA
Empirical Methods for Rate-Transient Analysis
- Arps Decline Curves - use with Fetkovich type-curves
- New Methods (ex. Power-Law Exponential)
Examples
