Discipline: Reservoir, Completion, Production engineering

Level: Basic/Intermediate

Duration: 5 days

Instructor: Jairo Balcacer


This course provides the concepts and procedures leading to an optimized completion design, considering the functional specifications, key components and constraints underlying different well completion concepts.

The design process will be driven by the company policies, industry standards and regulatory requirements along the different stages of the process. The understanding of the development of the Statement of Requirements (SoR) and Basis of Well Design or Completions Design (BoWD/BoCD) and the communication to the involved parties in the RACI Matrix for Well Completions will be covered, as well as the servicing requirements over the life of the well, along with the constraints that the completion design places on the drilling program.

The stages followed in the generation of completion costs estimates and the required accuracy of cost estimates at each stage will be reviewed, as well as the modifying well objectives and procedures based on previous results (optimization process)


This course is intended to provide the attendants (drilling, reservoir, completion, production engineers), with the proficiency needed for designing an optimum completion program that focus on attaining the highest well performance, and thus, the highest NPV to the company.
