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

  • Tight gas
  • Single- and multi-phase shale gas
  • Single- and multi-phase CBM
