IWCF WIPC Level 2 case studies
IWCF WIPC Level 2 · Put your knowledge to work in context.
The IWCF Well Intervention Pressure Control (WIPC) Level 2 is the entry certification tier in IWCF's well intervention pressure control programme, aimed at personnel working in critical well control positions during completion and well intervention operations. IWCF states that Level 2 is intended for assistant operators in wireline, coiled tubing and snubbing. Certification is built from two compulsory components - Completion Operations and Completion Equipment - plus at least one optional component chosen from Coiled Tubing Operations, Wireline Operations, Snubbing Operations and Subsea Operations, the last of which can be taken as an optional or standalone module. Candidates must attempt both compulsory components and one or more optional components in a combined certification programme, and must pass every component they are nominated for to gain the combined certificate. The IWCF WIPC Level 2 case studies are 5 cases and about 2,866 words.
1Packer Set, Annulus Pressure Creep, and Tubing Pressure Test
An operator is completing a well with 7-in, 29 lb/ft casing and 3½-in, 9.3 lb/ft N-80 tubing. The hydraulic-set retrievable packer is at 2,900 m TVD (3,050 m MD), with perforations at 2,850 m TVD.
