Course Description

During the past period, wireline formation testing (WFT) has emerged as one of the critical formation evaluation means in the upstream hydrocarbon exploration activities. Modern wireline testers (MDT, RCI, and RDT) have gradually but increasingly claimed some of the duties of conventional drill-stem test programs, as a result of high drilling cost, environmental protection, operational safety, and WFT technology advances. Discussions on the “WFT vs. DST/well test” topic have widely been held in a variety of professional and technical arenas, from pressure applications to fluid typing and sampling. This course is tailored to satisfy the interdisciplinary need of geologists, petro-physicists, and reservoir engineers, who have basic understanding of wireline testers, but have an increasing use of wireline testers or deal with WFT data and want to become more knowledgeable on this subject.  When the course ends, the participants are expected to apply the skills and lessons learned in designing better test programs, maximizing probabilities of getting quality tests, and benchmarking confidence levels to enhance results. The latest LWD formation testing technology and practice are also included in this course.
 

Course Goal

To enhance participants’ knowledge, skills, and abilities necessary for understanding and awareness of wireline formation testing and interpretation.
 

Course Objectives

By the end of this course, participant will be able to:

• Understand wireline formation testing technologies, applications, and limitations.
• Assemble wireline testing programs, tool configurations.
• QC pressure and fluid ID tests in the wellsite for the best quality data.
• Interpret pressure gradient data for in-situ fluid densities, fluid contact levels.
• Compare two gradient lines for reservoir connectivity/continuity.
• Perform error analysis and quantify uncertainties of P/D slopes and free water levels.
• Design and interpret pressure transient data for permeability.

Who Can Benefit

Geologists, petro-physicists, well-site supervisors, hydrodynamic specialists, reservoir engineers, geophysicists, and geo-data interpretation technologists of multidisciplinary formation evaluation and development teams that are actively engaged in G&G operations for hydrocarbon discovery and reservoir management.
