Geothermal Reservoir Engineering by Dr. Roland N. Horne

Dr. Roland Horne is Director of Stanford University Geothermal Program. In this course, he will explain the engineering aspects of geothermal energy recovery, with a specific emphasis on how to quantify the size of a resource and how to forecast its future performance.

The course will look at methods to analyze well condition, resource properties and
size, most efficient development strategy and design of reinjection schemes.

COURSE CONTENT

Overview

* Geothermal in the world – market history and forecast, relative costs of fossil fuel

* Geothermal reservoirs – definitions, structure, location, conceptual modeling,
fundamentals of geochemical analysis

* Thermodynamics of rock/water/steam systems – mass and energy balance, estimates
of reserves

* Properties of two-phase mixtures – flashing and condensation, capillarity and
adsorption, relative permeability

* Flow of fluids in porous and fractured media – treatment of heterogeneities in flow
field, transport of chemical and thermal fronts

Wellbore Calculations

* Wellbore heat loss – estimating downhole temperature while drilling and stimulating, well heat-up, estimation of reservoir enthalpy

* Wellbore pressure loss – estimation of downhole conditions, design considerations
with regards to wellbore diameter

* Analysis of pressure, temperature and spinner logs – feed point determination,
water loss tests, ambiguities in data

Well Test Analysis

* Pressure drawdown and buildup interpretation – estimation of reservoir and well properties

* Interference testing – determining reservoir pore volume and connectivity

* Injection testing – estimating productivity after drilling and completion

* Testing and equipment – procedure for designing a well completion test

Reservoir Simulation

* Volumetric – lumped parameter models, simple analytical model, distributed
parameter models, how to include adsorption effects in simulations

* History matching – methodology for matching the data, iterative schemes

* Numerical stability, errors, gridding and time stepping – procedures for
quantifying and minimizing numerical errors, error bound analysis

Reinjection

* Effects of injection – migration of thermal fronts through reservoirs, fracture flow
and flow through porous media, permeability changes due to quenching and
chemical reactions, boiling in steam caps and vapor-dominated systems

* Tracer test design and analysis – tracer material and quantity required, types of tests, strategy for monitoring wells, interpretation of measured returns

* Worldwide field experience with geothermal reinjection

WHO SHOULD ATTEND

This course will teach about engineering techniques to analyze geothermal reservoirs so that they may be developed efficiently. Both engineers and geoscientists should attend. The course will include material for both newcomers and experienced geothermal practitioners
