Well Testing, Completion Design and Operation, Well Stimulation and Workover Planning Course
Introduction:
This course is primarily designed for drilling, production and completion engineers and supervisors needing a practical understanding and an appreciation of well completion design and operation, well stimulation and work over planning. It explains how completion configurations are varied to meet well objectives and to maximize well productivity. Design concepts and methods are presented together with downhole tools and their selection criteria. In the development of a hydrocarbon reservoir, many wells are drilled and required to be completed, to allow the structure to be depleted. However, the drilling and completion operations are crucial to the long-term viability of the wells in meeting the specified objectives.
Course Objectives:
By the end of this course, participants will be able to:
- Evaluate for a given reservoir scenario the bottom hole completion options and make a recommendation based on well integrity and reservoir management requirements
- Identify, evaluate and recommend functional capability of completion strings for a variety of situations
- Describe the purpose and generic operating principles for major completion equipment components
- Identify the limitation of well completion schematically designs and potential failure mechanisms / operational problems with equipment
- Assess well safety requirements and capabilities inherent in well design
- Describe the integration of the various stages of completing a well
- List and flow chart a general procedure to run a completion string
- Describe the requirements to pressure test and retain well control throughout the completion process
- Define the need for full and accurate reporting and records to be kept
- Know the planning essentials prior to drilling and well completion procedures according to the principles of well completion design
- Develop the tubing performance curve and optimization of tubing dimensions for maximum by recognizing the methods of interval selection consideration and optimization of tubing dimensions for maximum productions
- Familiarize with the use of different subsurface completion equipment’s and accessories in relation to the selection consideration of packers and packer settings
- Operate the well-head equipment’s properly such as geometries and dimensions casing and tubing hangers
- Identify the different special consideration for horizontal and multilateral completions on wellbore, tubing and casing configuration
Who Should Attend?
Well and Senior Petroleum Engineers, Drilling, and senior drilling supervisors, reservoir and senior reservoir engineers, geologists, production and completion engineers, and supervisors needing a practical understanding and an appreciation of well completion design and operation, well stimulation, and workover planning.
