Why Choose this Training Course?

In the development of reservoir, an outsized variety of wells are drilled and need to be completed, to permit the structure to be depleted. However, the drilling and completion operations are crucial to the long run viability of the wells in meeting the desired objectives. The completion of each production and injection wells are needed to satisfy variety of objectives including:

  • Provision of optimum production/injection performance
  • Ensure safety
  • Maximize the integrity and dependability of the completion over the envisaged lifetime of the well
  • Minimize the full prices per unit volume of fluid produced or injected, i.e
  • Minimize the prices of initial completion, maintaining production and remedial measures

Primarily during this PetroKnowledge training course, we will focus on issues related to the completion string design new technology in addition to well interventions tools.

This PetroKnowledge training course will feature: 

  • Develop a high-level completion strategy for wells in a very sort of things
  • Select string, packers, and completion flow management instrumentality
  • Best practices of completion string design and installation
  • Discuss cases of using new technology in normal completion and sand control completions
  • Appraise well control barrier philosophy and testing during well interventions

What are the Goals?

By the end of this PetroKnowledge training course, participants will learn 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 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

Who is this Training Course for?

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

  • Petroleum Engineers
  • Production Technologists
  • Production supervisors and engineers
  • Completion supervisors and engineers
  • Drilling supervisors and engineers
  • Work-over and well service supervisors

How will this Training Course be Presented?

This PetroKnowledge training course will be presented using properly designed slides, some and animation on relevant issues. A printed manual containing all the slides and/or electronic form in PDF will be delivered to each attendant. Teaching methods include several examples of actual well intervention programs.

Organisational Impact

The organization will gain, in sending their employees to attend this particular PetroKnowledge training seminar, the following:

  • Reduction in the cost of the well and the proper selection of production string
  • Ensuring the well integrity and avoiding all risks during ringless operations
  • Extending the well life and control it, achieve the optimum production using well interventions instead of normal rig operations

Personal Impact

  • Obtain integrating knowledge of well completion design
  • Hone their knowledge and get the self-confidence in designing proper completion
  • Get the latest technology in well operations
  • Solving and avoiding the problems which impact on the optimum production, and well integrity
