1 Design tubing Describe basic design principles (burst, collapse, tension, compression that the tubing will encounter) for the anticipated pressure/temperature environment and associated expected flow or injection rates. Design a tubular system given a set of completion, stimulation, production or injection requirements.
2 Select and design completion equipment Discuss the need for various completion equipment components including packers, flow control devices, and subsurface safety valves. Select the appropriate completion equipment needs for a given completion scenario and associated metallurgy.
3 Formulate perforation system and scheme Describe the basics of perforating options including phasing, diameter, depth of penetration, and spacing. Select an appropriate perforation scheme and delivery method (i.e. wireline vs. tubing-conveyed).
4 Determine need for and design of sand control Differentiate between the various sand control processes such as standalone screens. gravel packs, etc. Calculate the required screen size and gravel size for a given mobile solids sieve analysis.
5 Design an acid or other reactive fluid stimulation treatment Differentiate between acid or other reactive fluid treatment types such as matrix treatments, fracturing treatments, and soak treatments. Quantify the controlling factors and calculate the maximum injection rates and pressures to pump a matrix stimulation.
6 Design a hydraulic fracturing treatment Describe basic concepts and requirements (proppants, fluids, conductivity, equipment needs, mechanical properties, rock deformation, fracture mechanics, diversion options, etc.) Plan a hydraulic fracturing treatment incorporating appropriate treatment scheduling, pressure calculations, leakoff behaviors, diversion requirements and HHP needs.
7 Design and understand a coiled tubing operation Describe basic concepts and requirements (nozzles, tubing hydraulics, operations, fluids, viscosities, carrying capacity, well operations, etc.) Plan a coiled tubing operation incorporating tubing sizing, fluid selection, bit and nozzle selection, sequencing, and well control requirements.
8 Determine completion fluids Describe the need for non-damaging completion fluids given reservoir and well properties. Identify non-damaging completion fluids for various formations and associated mineralogies.
9 Develop a recompletion Elaborate the definition of a recompletion and the potential need for such. Determine the need for remedial cementing operations and other potential remedial operations that may be required for a recompletion procedure to proceed.
10 Maintain well integrity Discuss the need to maintain wellbore integrity during completion operations to protect groundwater and honor other regulatory and safety requirements. Explain the well life cycle and the requirements to maintain well integrity through to well abandonment and beyond.
11 Maintain regulatory compliance Describe the expectations and need to comply with regulatory processes and how to determine those processes in a given region. Elaborate the processes required to comply with regulatory requirements. (for example, submission of fluid compositions to regulatory bodies; PPE requirements for given operations).
12 Incorporate diagnostic tools and procedures Identify the various diagnostic tools and procedures available for completion, stimulation and recompletion needs Select an appropriate diagnostic tool or process for a given need.
13 Wellhead tree design Discuss the basic needs for a wellhead and define the components. Design a wellhead tree assembly for a given set of completion parameters.
14 Determine presence of formation damage Identify the various types and causes of formation damage Identify the causes of formation damage in a given well scenario and determine options to eliminate further damage
