Geosteering works by comparison. The measurements coming from the bit are compared with a type log from an offset well, and the difference tells the geologist where in the stratigraphic column the well is and which way the beds are dipping. From that, the team decides whether to build, drop, hold or turn.

The quality of the pre-well model sets how well this works. A good model with a reliable type log, a sensible structural framework and a defined target window gives the team something to steer against. A poor one leaves the geologist interpreting from scratch while the well drills ahead at thirty metres an hour.

Steering is a team activity under time pressure. The geologist interprets, the directional driller executes, the drilling supervisor weighs the operational consequences and the decision has to be made in the time it takes to drill a stand. Clear roles, agreed decision criteria and good communication matter as much as the interpretation itself.

By the end of this training, participants will be able to:

• Define well placement objectives and target windows.
• Build a pre-well geological model and correlation framework for steering.
• Describe logging while drilling measurements and their use in geosteering.
• Correlate measurements against type logs while drilling.
• Determine structural dip and recognise faults from drilling data.
• Interpret position within the reservoir from measurement response.
• Make steering decisions and define build, drop and turn requirements.
• Communicate effectively between geology, directional and drilling roles.
• Work within the operational constraints on steering.
• Evaluate well placement results after drilling.

The course is instructor-led and interpretation-based, assuming no prior geosteering experience. Participants work through steering exercises using real logging while drilling data, making correlation interpretations and steering decisions as the well advances. Cases include wells that were placed well and wells that left the target. Participants are encouraged to bring their own data for discussion.

Organisations sending participants to this training will:

• Improve reservoir contact and well productivity through better placement.
• Reduce time spent out of the target zone.
• Improve communication between subsurface and drilling teams.
• Improve pre-well model quality for steering purposes.
• Build in-house geosteering capability.

Participants will:

• Understand how geosteering works and what it depends on.
• Be able to build and use a correlation framework.
• Be able to interpret logging while drilling data for position in the reservoir.
• Be able to make and justify steering decisions.
• Be able to work effectively in a geosteering team.

• Wellsite and operations geologists
• Drilling engineers
• Directional drilling staff
• Petrophysicists supporting drilling
• Reservoir engineers involved in well placement
• Graduate geoscientists entering drilling support roles

Upon successful completion of this training course, delegates will be awarded an official Certificate of Completion issued by the Petroleum Engineers Association (PEA), an ISO 9001:2015 certified training organization. The certificate carries 10 Credits and formally records the total learning hours completed.

Each certificate is signed by the Course Facilitator and the CEO of the Petroleum Engineers Association, and serves as verifiable proof of professional training that delegates can present to employers and professional bodies worldwide.
