Applied Drilling and Well Engineering

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

Notes:

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.
