Completions Design

This course is focused at taking a basic awareness of wells and completions and expanding it to cover the design process and all the key decisions that are made in completion design from the various reservoir completions to the upper completion and associated threats and opportunities. The focus is on the overall design rather than the detail of completion equipment from specific vendors. It assumes some knowledge of general well intervention methods (slickline, coiled tubing, etc.), but does not significantly expand this knowledge. The course covers land, platform and subsea wells.

The course covers:
· Types and configurations of completions.
· The completion design process.
· Inflow performance, skin and formation damage.
· Perforating; selection, deployment and interface with rest of completion.
· Stimulation and impact on completion and flow performance with coverage of modern horizontal multifrac tools.
· Open hole, non-sand control completions including open hole packers and horizontal well clean up.
· Sand control; when do you need it, basic types and selection guidelines. Includes standalone screens, ICDs, various gravel packing techniques, frac packs and expandable screens.
· Tubing sizing, flow estimation and liquid loading.
· Artificial lift; types and selection criteria, interface with drilling, reservoir and facilities. Design of gas lift and ESPs included.
· Production chemistry impacts on completion, prevention and removal (scales, wax, asphaltene, hydrates, and souring).
· Metallurgy, corrosion, and erosion; metal types and selection of.
· Elastomers and plastics; types and selection of.
· Tubing stress analysis; picking the grade and weight of tubing, plus selection criteria for packers and expansion devices. Interface between tubing stress analysis and casing design.
· Completion equipment; basic types of equipment, reliability and selection criteria for each (tree, safety valve, mandrel, packers, expansion devices etc.)
· Completion installation; importance of wellbore clean-out, function and types of brines, pointers for efficient completion installation.
· Non-conventional wells; types and when / where to use them (multilaterals, smart (intelligent) wells and also SAGD, CO2 sequestration, CBM, etc.)
