WATERFLOODING

FUNDAMENTALS, DESIGN AND MANAGEMENT

A cargo de Daulat Mamora del Texas A&M University.



Bogotá, del 17 al 21 de Agosto


Course description
This is an intensive, applied course in waterflood design and management. Certain theoretical aspects of waterflooding (e.g. Buckley-Leverett fractional flow) will be covered. Applied topics covered will include: reservoir performance analysis, well injectivity estimates, waterflood candidate selection, waterflood forecasting (includes hands-on analytical and simulation modeling), impact of heterogeneity on waterflooding, selection of waterflood pattern (technical and economic considerations), waterflood performance analysis (includes analysis of production decline and fall-off tests), and design of waterflood injection and production facilities.


Intended Audience
The course is meant for petroleum engineers who wish to master the design and management of waterflooding. It is best suited for engineers with at least three years reservoir and/or production engineering experience. Knowledge of running ECLIPSE 100 is advantageous but not essential.

Course Outline
Day 1

Introduction to waterflood

  • The total system – injection, production, pattern

  • Factors affecting optimization of the total system

  • Waterflood design - a multi-disciplinary effort

  • Waterflood patterns

  • Operational constraints – waterflood offshore


Reservoir engineering fundamentals

  • Why waterflood?

  • Material balance

  • Reservoir pressure prediction

  • Flow regimes - diffuse and segregated flow

  • Injectivity/productivity calculations for different pattern types.

  • Areal and vertical sweep efficiency

  • Displacement efficiency – Buckley-Leverett theory

  • Recovery efficiency

  • Exercises to calculate (i) well injectivity for various waterflood patterns, (ii) sweep efficiency



Day 2

Analytical models

  • Waterflood design. Factors to consider in selection of pattern type and size.

  • Analytical forecasting models: theory and application.

  1. Diffuse flow models: Buckley-Leverett, Dystra-Parsons, Craig-Geffen-Morse models

  2. Segregated flow model: Dietz model

  • Exercises to estimate waterflood performance using analytical waterflood models (VBA programs provided)



Day 3

Simulation

  • Hands-on waterflood reservoir simulation.

  • Class will develop and run 3D model of one-eighth of 5-spot pattern using ECLISPE 100 (input data will be provided).

  • Compare reservoir simulation and analytical model results.

  • Exercises to estimate production performance for 5-spot pattern using ECLIPSE 100 simulator


Day 4

Pattern selection

  • Discounted cashflow analysis

  • Selection of pattern based on economic criteria and operational constraints

Waterflood surveillance

  • Decline curve analysis

  • injectivity and fall-off test analyses

  • Hall plot

  • Infill drilling

  • Exercises to (i) calculate cashflows using estimated waterflood performance, (ii) analyze fall-off tests, (iii) analyze Hall plot for injection well

NOTE:

:

Course will require PC’s (minimum Pentium 4) to be made available to the class (maximum two course participants to a PC). PC’s will be used for class exercises, analytical modeling and simulation. For simulation, ECLIPSE 100 will need to be installed on the PC’s.
