Customer challenges
- The job was carried out in a Petronas field located in offshore Sarawak. The field is a part of a cluster which supplies gas to two LNG trains located in East Malaysia
- With production declining, the objective for the customer was to drill additional wells to deliver 250MMscf/d to both sustain and fulfil the customer's gas supply agreement commitments to supply 500MMscf/d to both LNG plants
- Petronas drilled and completed three deviated gas wells (completed as 7" monobore's with pre-drilled liner) and engaged Expro (under the Pan Malaysia Well Test contract) for well unloading and clean-up operations with maximum planned flow rates of up to 150MMscf/d
- This project was extremely important for the overall gas supply requirements and also for the technical user groups as this was the first time they were conducting a complete well test on a high rate gas well
Expro Excellence
- The customer's test objectives for the wells required a test separator and also included several firsts for Expro in the region:
- Vertical separator with Coriolis meter
- EDGE wireless data acquistion
- Data to desk service
- ESD SIL2 system
- While these services/technologies have been provided as discrete enhancements on other projects, combining all of these in a single project
- The EDGE wireless sensors, Data to desk and ESD SIL2 system were offered as technology differentiators to Petronas with a view to inclusion on upcoming projects under the ongoing contract
- This project incorporated the design and equipment selection parameters which were applicable to high rate flowbacks:
- 90ft booms to minimise heat radiation
- Water cooling and personnel protection
- Use of green burner to minimise environmental impact
Value to client
- The project was executed successfully and the customer was able to flow test the wells to the planned maximium rate of 150MMscf/d
- Our EDGE wireless package was easily deployed over the rig and platform in what would otherwise have been a cumbersome wired installation
- Expro's Data to Desk service allowed real-time data to be shared via a web browser on multiple mobile data platforms - project stakeholders were very appreciative of the visibility and control. The Expro D2D application provided on this high profile project
- The Electronic-ESD SIL2 system was appreciated by Petronas engineers for its features:
- Fast reponse times - critical in a high rate gas flowback application
- Quick and easy installation
- Real-time interface EDGE package
- Simple interface with rig/installation
