Production Operation & Well Intervention (PRE43)
27-31 January 2025 5 days Vienna, AustriaCourse Fee: 4050 EUR + VAT
Description
This course covers the major aspects of production operations, with focus on the loss of well integrity caused by annular pressures resulting from inadequate cementing, corrosion issues, etc.
The importance of slickline and wireline operations is discussed in detail. Moreover, emphasis is placed on wellhead and X-mas tree components, along with integrity issues associated with them. coiled tubing (CT) operations are highlighted as a crucial component in field operations. The operation of hydraulic workover units is described, with its importance underscored.
The course addresses the importance of well integrity and the role of CT in well interventions such as production logging, fishing operations, scale removal, stimulation operations, etc.
Course Level: Foundation / Skill
Instructor: Antonio Abreu or Luis Remisio or Cipriano Costa
