1.5 CEU What is a CEU?

Who Should Attend

Well-site and office-based personnel who seek a basic understanding of the processes involved in successful well bore placement. Geologists, geophysicists, petrophysicists, reservoir engineers, and drilling engineers with little to no previous geosteering exposure can benefit. Basic knowledge of geologic concepts, trigonometric relationships and familiarity with basic petrophysical LWD log response is assumed.

Objectives

By the end of the course, participants should be able to accomplish the following:

• Identify key participants in planning lateral section and determining data requirements for steering.
• Apply correlation procedures in critical areas of a build section in order to land the well bore relative to the desired target zone.
• Determine stratigraphic position of the well path in high angle/horizontal lateral sections using a potential variety of methods and tools.
• Determine apparent formation dip along the well path with a variety of methods and tools.
• Interpret image logs in order to determine formation apparent dip and stratigraphic trajectory of well path.
• Select directional drilling targets that fit with target objectives, operational limitations, and completion design parameters.
• Determine optimum well path from integrating all available data and making most reasonable geologic projections.
• Appraise the most useful type of data necessary for steering from a wide variety of options.

Content

This course is meant to introduce key concepts in the planning and execution of lateral well bores. Practical experience is gained through presentation of numerous examples of well placement techniques using a variety of data- emphasis is given to real-time steering operations. The course material will progress through basic steering practices to more complex analysis utilizing LWD tools in both reactive and proactive steering environments. Fundamentals of forward modeling of resistivity data will also be examined, as this is the current, most common “look ahead” technique utilized in proactive steering.

The geosteering techniques taught may be applied to all reservoirs. The emphasis on unconventional, liquid-prone reservoirs is highlighted by numerous case histories which will show completion strategy becomes a fundamental determining factor in steering practices. A general overview of new applications of LWD technology will also be presented.

In summary, the course is designed to give the attendees the fundamental tools necessary to determine well bore position relative to a target zone, to project forward with the tools available in order to modify the well path while drilling, and the awareness to integrate all pertinent input completion parameters and long term strategy to ensure the selected well path is the optimum.
