A work performed after the original completion of the well is a minor work-over or intervention while other operations carried out in oil or gas well during its life cycle can be termed as a major work over if the completion is pulled which will change the configuration of the completion of the well.
In HPHT wells there are a lot of particularities conducting to a very expensive management of the field / reservoir due to necessity of using special equipment and tools able to withstand high pressure and temperature. The intervention in such wells calls for special metal alloys, high resistant elastomers if used as part of tool or equipment and top experienced personnel to work with.
Primarily in this PetroKnowledge training course, we are concerned with problems associated with the completion string designed particularly for HPHT wells. Production logging will help in well problem diagnosis using wireline or coiled tubing to run logging tools and all problems connected with the reservoir for adjustments and further production from the wells. In general, problems associated with the completion string can be classified into problems which arise in the tubing bore and which can be corrected through tubing operations and problems which necessitate the retrieval of the completion string from the well.
This Advanced HPHT Well Intervention Operation course will provide a good approach on the impact of interventions and completion design in maximizing field production and increasing recoverable reserves. It also emphasizes the importance of intervention methods (slickline, electrical / wire-line line and coiled tubing) all designed and manufactured to work in hostile environment with HPHT, during the whole lifetime of the well in-order to keep the well on production with profitable rates.
The PetroKnowledge training course will feature:
- Introduction to the variable nature of well interventions in HPHT wells
- Proper completion string design and installation in hostile conditions
- Identify Wireline best practices and applications for HPHT wells
- Identify Coiled Tubing demands and applications in HPHT wells
- Appraise well control barrier philosophy, SOP and testing during well interventions in HPHT wells which are more strict and accurate
