By the end of this training course, participants will learn to:

• Recognize the influence of drill string mechanics
• Understand how to avoid drilling problems
• Appreciate the environmental effects of drilling activities
• Implement techniques to control non-productive time
• Effectively identify and monitor key performance Indicators (KPI)
• Implement real time management of well construction and optimization

This CDGA training course is designed for all professionals working in the field of well engineering, oil and gas exploration, geology and reservoir modelling.

It is also quite beneficial for other people involved in the upstream oil production as it shows the interdependence of the data between the departments.

This CDGA training course is suitable to a wide range of professionals but will greatly benefit: 

• Reservoir Engineers
• Petroleum Engineers
• Risk Managers
• Drilling Managers
• Field Service and Related Operations
• Company Men
• Tool Pushers
• Drillers

Define Concept

Compare to other goals and objectives of well drilling and construction

Overview of various areas where we have control over the well construction process:

• Type of well
• Accurately define well objective(s) and service life
• Identify mandatory and optional elements of well design

Hole diameter

Pressure capacity

Well inclination with the reservoir/target

Casing/hole diameter clearance

Casing or liner?

Mud type/rock interaction

Logistics issues (storehouse, quality assurance, property protection, etc.)

• Well location
• Spud/Completion deadlines
• Data requirements (also level of accuracy needed)
• Contract and agreement terms
  
  

Overview of various areas where we do not have control

• Weather

Workshop putting it all together

1. Using real data provided by Petronas and proposed well (fictional well proposal):
2. Organize data into useful format.
3. Extract information from data set to use and define technical limits of various phases of well construction.
4. Decide on KPIs.
5. Identify Lessons Learned from data set.
6. Identify contingencies requiring pre-planning.
7. Create time schedule of well (time/depth curve, identify major timeline events and planning decision Points).
