Cased Hole Formation Evaluation for Reservoir Monitoring
Format and Duration:
3 days
6 sessions
Interpretation techniques using modern cased hole logging tools are presented to understand, analyze, and resolve a variety of reservoir and near-wellbore production situations. New or existing cement bond logs are used to determine possible completion strategies or help determine near wellbore conditions that are affecting well performance. Reservoir monitoring logs and production logging data can be used to evaluate both the wellbore and reservoir performance to extend or improve the economics of the well. Wellbore integrity logs will monitor the condition of the casing strings not only for completion operations but also HSE concerns for the life of the well. For each of these categories the proper design, tool selection and interpretation are covered.
Business Impact: After the well is completed both the well and reservoir will need to be monitored during the lifetime of that well to maximize the economic return of the investment. The use of cement evaluation, well integrity logs, reservoir evaluation logs and production logs will assure that the completion will achieve maximum production from both the initial and possible bypassed reservoirs while maintaining HSE requirements. These tools support the operational need to identify the location and quantity of remaining hydrocarbons, in support of improving oil and gas recovery from secondary and possible tertiary production of the well.
Feedback
It was very good training with coverage of Basic and advance stage analysis. It meet the requirement of knowledge in Producing field. It should be a regular training (at least twice in a year ) to cover more cased hole tool / case study analysis etcs.
Schedule
Duration and Training Method
This is a classroom or virtual classroom course comprising a mixture of technical interactive sessions with examples and discussion. The basic tool functions, design of the logging operations, and interpretation of the results will be followed by examples of the various tools. Attendees are highly encouraged to provide examples for their problem wells and possible solutions will be addressed by both the instructors and participants.
Course Overview
Learning Outcomes
Participants will learn to:
- Formulate Cased Hole (CH) logging objectives to maximize results.
- Conduct quality control of both various CH logging tools and operations.
- Determine the proper tool selection for production logging
- Assess well production profiles and zonal fluid contributions.
- Select CH logging tools/techniques to evaluate the well and reservoir.
- Evaluate formation fluid saturations and monitor fluid contact movement.
- Assess multi-phase flow measurement results using a combination of PL and reservoir monitoring logs.
Course Content
This practical course discusses Casing Evaluation including multi-finger calipers for internal corrosion, ultrasonic tools for both internal and external conditions, and other casing evaluation tools including magnetics, flux leakage and eddy current.
It also covers the full scope of Formation Evaluation through casing using pulsed neutron tools as well as basic and advanced technologies for Evaluation of Multi-Phase Fluid Movement in vertical, deviated, and horizontal production and injection wells.

Instructors
Gary Frisch
Background
Gary Frisch has over 34 years of experience in creating, developing, interpretation of petrophysical data concentrating in the cased hole environment. He began as an open hole field engineer with Halliburton Logging Services in Farmington New Mexico. He was transferred to Houston to work in Interpretation and Development in November 1990. He worked on thin bed interpretation but soon migrated to the cased hole environment where he designed and wrote the production logging software including multiprobe array tools. He then developed leading edge computer programs for cement evaluation for multiple type of measurements including sonic, ultrasonic and attenuation that provides interpretation of any cement evaluation tool currently in use throughout the industry. Authored more than 25 technical papers on both cased and open hole log interpretation, holds 15 U.S. patents along with several international patents. Member of Society of Petro physicists and Well Log Analysts (SPWLA) and the Society of Petroleum Engineers (SPE).
Some of the various highlights include being responsible for the interpretation of the cement and casing evaluation for the Macondo relief wells DD1 and DD3 using data from both Halliburton and Schlumberger. Combined multiple open hole and cased sensors to generate a new evaluation method for well abandonment. Technique has been used successfully in multiple well abandonments in the GOM for multiple operators including cut and pull of multiple casing strings. He also developed several programs to evaluate and quantify well integrity from mechanical, ultrasonic, electro-magnetic and formation compaction tools. Created interpretation packages from the raw data to complete solutions ranging customized spreadsheets to three-dimensional images.
