Directional drilling Horizontal and side track
Successful Deviated, horizontal and sidetracking wells require new considerations, interdisciplinary planning, and special techniques. This 7-day course addresses the critical need for a proper understanding of all aspects of horizontal and deviated well drilling and completion processes that make these wells unique. Basic understanding of important reservoir characteristics, hole stability, formation damage, and crucial zone isolation are just some of the issues critical to successful horizontal and deviated wells addressed by this course. A combined practical and technical theme is employed, with emphasis on economy and efficiency in drilling and completing these wells. Participants develop an appreciation for the complexity of these wells and become equipped to design programs for wells from drilling through completion and production.
By the end of the course the attendees will be able to :
- Plan a two-dimensional directional well.
- Plan horizontal wells based on the objectives of the well.
- Determine the best sidetracking application.
- Determine declination and non-magnetic drilling collar selection.
- Directionally drill with rotary BHA’s, jetting, whip stocks, motor, steerable motors, and rotary steerable systems.
- Select the correct type of well for specific purposes.
- Plan the well given well head, and target data.
- Select the appropriate down hole tools to drill the well.
- Understand the operation of down hole measuring equipment.
- Interpret survey data, carry out survey calculations and plot survey positions on the will plan.
- Recognize and avoid down -hole problems.
- Analyze well shapes and project ahead
