Instructor: Tex Boratko (Schlumberger Wireline)

Date: Wednesday, May 6

Time: 8:30-11:00 AM

Meeting Place: Salon IV

Course Fee: $45.00

Course Description: When was the last time you ran a wireline formation test? A lot has changed since then.

This course gives an overview of the fundamentals of pressure and fluid test techniques and data interpretation. It covers the evolution of wireline test tools up to the present generation including tools optimized for fractured reservoirs (including Monterey), pressure test tools optimized for tight reservoirs (including Diatomite), and a cased hole tool that drills a hole in the casing, tests the zone, and then plugs the hole.

It will provide you with the basics of which tool configuration to run, how to pick the best zone to test, how long to stay on each test, how to quality control the data, and how to interpret the data in the field.

Case studies will be presented showing the value of test data in single wells and field development projects.

Instructor Tex Boratko is the US Land Reservoir Domain Champion for Schlumberger Wireline. In this role he is involved with Schlumberger's Wireline pressure testing, fluid sampling, and formation coring tools. He has been with Schlumberger for 29 years, starting as a Wireline field engineer in 1980 after graduating with a Bachelors Degree in Mechanical Engineering from Northeastern University in Boston. Tex's field work consisted of Wireline logging throughout California, Oregon, Nevada, and Washington state. Since then he has held various interpretation, sales, and management positions with Schlumberger in California, the Rockies, and the Gulf Coast. Tex is a member of the SPE, AAPG, and SPWLA.



Instructor: Dr. Peter Kaufman (US Land West, Denver)

Date: Wednesday, May 6

Time: 1:00-4:30 PM

Meeting Place: Salon IV

Course Fee: $45.00

Course Description: Geomechanics, the applied study of the mechanical behavior of rock, is important throughout the life of a field, from discovery to abandonment. An understanding of the mechanical properties, pore pressure, and the stress state in the earth can help guide decisions from drilling and well placement to pore pressure prediction to completion optimization. A better understanding of the sources and applications of geomechanical data can enable a geoscientist to make better field development decisions that can result in large cost savings and increased revenue.

This short course will begin with an overview of basic concepts of geomechanics, covering the basics of stress and strain, mechanical properties of rocks, and failure mechanisms. Geomechanical data sources will be described, with an emphasis on log and core measurements.

Following the introduction to geomechanics, we will discuss how these mechanical properties can be determined from acoustic logs, with particular attention to how anisotropy (azimuthal and layering) plays an important role in the mechanical characterization of geologic formations. An emphasis will be placed on how the mechanical properties of the formation impact stimulation and production.

The final third of the course will be dedicated to advanced applications of acoustics and geomechanics, relating natural fractures to acoustic anistropy, describing the process for building a 1D mechanical earth model, and showing how to integrate 3D geomechanics with reservoir simulation to predict how production will impact rock properties and the stress state within the earth and what impact these changes will have on field performance.

Throughout the course, numerous case study examples will be shown to reinforce the geomechanical concepts.

Dr. Kaufman started his professional career in 1995 with the Basin Modeling Team for Amoco E&P in Houston, providing basin modeling technical support for exploration teams evaluating acreages in Trinidad, Venezuela, China, and Canada. In 1998, he joined Schlumberger-Doll Research researching workflows and software to capture and utilize geological outcrop analogs of faulted and fractured reservoirs. After a two-month secondment to Schlumberger's Abingdon Software center in 2001, Dr. Kaufman turned his research focus to modeling fault and fracture properties in reservoir simulation. He authored the requirements and specifications for the Fault Property Calculator module for FloGrid and Petrel and developed an ECLIPSE simulation approach for unstructured gridding of fractured reservoirs. In 2005, Dr. Kaufman moved to Schlumberger's Data & Consulting Services group in Pittsburgh, where he worked primarily on reservoir geomodeling of gas storage projects and characterization of fracturing in emerging shale gas plays until 2007. In 2007 Dr. Kaufman moved to his current position as the technical lead, Geomechanics for US Land West based in Denver. Dr. Kaufman holds a Ph.D. from MIT in Geology and Geophysics and advanced courses in Petroleum Engineering from the University of Texas, Austin.
