Directional Drilling is one of the most fascinating subject areas in the oilfield – with high tech tools able to drill into the smallest of targets great distances from the rig.
The course learning outcomes are:-
- To enable delegates to understand why points on the Earth (e.g. Geographic North & Magnetic North have been referenced as they have;
- To enable delegates to understand why certain survey tools reference certain points of reference (e.g. magnetic tools, gyroscopic tools, inertial tools etc.) and how positional calculation are carried out;
- To enable delegates to know what goes on inside ‘black box’ software survey programs;
- The tools used for directional, horizontal and multi-lateral drilling and how they are used;
- How the Directional Drillers & MWD Engineers drill from the vertical to the target(s) selected by the Operators sub-surface groups.
Presentation material is through the use of detailed Manuals, PowerPoint, Design Calculations (& Graphical Analysis), case histories, videos and digital film.
Duration: 5 Days
Skill Level: Intermediate
This course covers the following topics:
- Latitude, Longitude, How the Earth has been ‘represented’ in terms of positional co-ordinates
- How data is acquired and used to determine survey tool & well position
- Survey tools: Magnetic, Gyroscopic, Inertial & Ring Laser: How they work and how they are used on the rig / downhole
- Directional Well Design: Vertical, KOP, Tangential Section, Dropping Angle, Horizontal & Multi-lateral drilling
- Tool Face / High Side, Inclination, Azimuth, Measured Depth & TVD
- Problems associated with high-angle wells and how they are solved (e.g. hole cleaning, high torque, high drag)
- Teamwork Exercises: Designing a Directional Well & Tools Listing
- Detailed Design Procedure, Example Calculations & Graphical Analysis (Oilfield Units & S.I. Units)
- Drilling Engineers / Senior Drilling Engineers / Technical Assistants
- Rig Crew: Assistant Drillers, Toolpushers
- Service Personnel.
Prerequisite: General Oilfield Knowledge.
