Applied Drilling and Well Engineering

Steve Nas

The objective of this 5 days Applied Well Engineering course is to provide well engineers with an advanced and practical insight into the Well Design and Well Construction process. This course approaches well construction as a design process. In doing so each topic is addressed by the participants by defining objectives and creating a basis of design. Once this has been completed the detailed design process is addressed.

The course is scheduled around an actual well and it is combined with practical examples to enhance the theoretical and practical knowledge of the candidates. As the course progresses, complexity is increased, requiring the candidates to re-evaluate objectives as new conditions are introduced. The course addresses all aspects of well design and well operations including aspects that are generally conducted by contractors. 

Each of the participants will work and create a detailed drilling program, which will include costs, timings, risk assessments and contingency planning. Once the well design is completed the program will be used to review operational management and optimization opportunities.

DAY 1 - Introduction to Well Planning and Formation Temperatures

The first day introduces the well planning process, Objectives and Basis of Design as well as the general standards and guidelines that need to be referenced. Introducing the objectives of the well to be designed and working through the basis of design including first pass of drilling times and costs. From the initial well proposal, we add the understanding of pore, fracture pressures and the temperatures as they are provided to the well engineer. The objectives are to incorporate the formation pressures and temperatures into the basis of design and understand the implications. Various methods for pressure determination and potential variations in pressure predictions will be introduced

For offline training candidates are required to bring their own laptops with excel and must have the ability to use excel for this course. No programming knowledge is required but complex formulas and  graphs are used together with spreadsheets during the course.

What is Applied Drilling and Well Engineering training course objective?

At the end of the course, the participants will understand and be competent in:

  • Participants gain a solid understanding of understanding objectives and creating a basis of design for each activity before working the details of their well program.
  • Participants are made aware of the complexities and interaction between various components of well design and the subsequent well operations. 
  • Participants will gain a good understanding of well design aspects provided by contractors, they will also gain an understanding of the data requirements for the contractor work scopes. 
  • Participants gain a better understanding of the operational management, the risk management and mitigation aspects of well design and well operations and the influence these have on well objectives. 
  • Participants can go back to their operational roles after the course with a better understanding of the well design process.
