IWCF WIPC Level 2 study plan

Define the five primary completion types (single-zone cased-hole, openhole, gravel-packed, multi-zone, intelligent) and list the barrier envelope of each from memory

Sketch a tubing string from memory labeling tubing joints, blast joint, flow coupling, no-go nipple, landing nipple, sealbore packer, and safety valve with the function of each in one line

Explain how a packer sets and releases mechanically, hydraulically, and by wireline, and identify which setting method each of five named tools uses

Describe the sequence of a basic cased-hole completion from perforating through packer setting to tree installation

List the API and ISO references that govern tubing, packers, and completion accessories and state what each covers

Compare packer types ( retrievable, permanent, sealbore, gravel-pack, ESP) on setting method, release method, pressure rating, and temperature rating in a table built from memory then corrected

Explain the function and failure modes of subsurface safety valves (SCSSV/SSSV) including flapper, ball, tubing pressure actuation, and control line

Describe gas lift valve operation, mandrel types, and unloading sequence

Identify completion accessories (circulating valves, chemical injection mandrels, gauge carriers, sand screens, inflow control devices) and state where each sits in the string

Calculate hydrostatic pressure and differential pressure across a packer for three given depth and fluid-weight scenarios

Walk through the barrier philosophy for a live well: primary, secondary, and tertiary barriers and which completion equipment provides each

Explain annular pressure buildup, trapped annulus, and thermal expansion effects and how completion design mitigates them

Describe sand control selection logic (standalone screen, gravel pack, frac pack) against formation and production parameters

Outline completion fluid selection, filtration, and cleanliness requirements and the consequences of solids in the wellbore

Explain how a completion is tested after installation (pressure test, inflow test, valve function test) and what constitutes a valid test

Describe coiled tubing surface equipment: injector head, stripper, BOP stack, reel, and pressure control equipment, and state the function and failure mode of each

Explain CT string fatigue, cycle counting, and the role of the fatigue management system, and interpret a sample fatigue log

Describe CT well control: stripping, snubbing with CT, and the procedure for tripping with pressure on the well

Explain CT applications (wellbore cleanout, milling, acidizing, nitrogen lifting, plug setting) and the limits of each

Calculate CT reach or a basic force balance for a given well geometry and string size

Distinguish slickline, braided wireline, and electric line by capability, typical use, and pressure control equipment

Describe wireline pressure control: grease injection head, flow tubes, BOP, lubricator, and the procedure for lubricating in and out of a live well

Explain wireline logging conveyance, depth control, and the risks of toolstring sticking and cable damage

Describe common wireline interventions (perforating, plug setting and retrieval, gauge runs, valve shifting) and their well control implications

Explain wireline tension, weak point selection, and the procedure when a toolstring becomes stuck

Describe snubbing unit components (slips, traveling and stationary, jack, rotary table, BOP stack, work window) and the function of each

Explain the difference between stripping and snubbing and when each is used, including pipe-light and pipe-heavy transition

Describe snubbing well control: kick detection, shut-in, and the procedure for handling pressure while tripping

Explain buckling and the effect of snubbing forces on pipe, and how to calculate the point of neutral buoyancy

List snubbing applications (live well workovers, plug drilling, fishing, underbalanced operations) and their hazards

Describe subsea completion architecture: subsea tree, tubing hanger, wellhead, umbilical, and control system, and the function of each

Explain subsea well control: BOP stack, EDS, and the barrier philosophy for a subsea well

Describe subsea intervention methods (rig, riserless light well intervention, subsea wireline, ROV) and their limits

Explain subsea tree types (vertical, horizontal) and their installation and workover implications

Describe hydrate, wax, and asphaltene risks in subsea flowlines and how they are managed

Revisit every domain's weak points identified in weeks 1-7 and close each gap with a written explanation

Complete a timed 60-question mixed mock covering all six domains and record the score by domain

Explain the common well control thread across CT, wireline, snubbing, and subsea operations in a single written summary

Rehearse the barrier philosophy and pressure control fundamentals until they can be stated without notes

Build a one-page formula and reference sheet for hydrostatics, differential pressure, and neutral buoyancy
