Success for permanent downhole temp sensing

Demonstrated in onshore and offshore projects in Brunei BSP


Cologne, Germany –?? In the oil and gas industry, there is keen interest and high demand for low-cost, reliable, and easily installable systems to enhance downhole production and recovery.

???Installation of LIOS DTS in the Darat Field in Brunei has proven to increase the value of the wells from our customer significantly because of early detection of faulty gas lift valves, resulting in quick repair and increased production.???

In a co-operation between Shell International Exploration and Production (SIEP) and LIOS Technology GmbH (LIOS) the feasibility and economical added value of permanent downhole DTS, or distributed temperature sensing, have been successfully demonstrated in a number of recently deployed onshore and offshore projects in Brunei BSP.

This shows that once certain maturity and robustness in a technology has evolved and an agreement on standards has been implemented low-cost equipment can be designed, manufactured, and deployed even for low-cost wells.

The applied design and working practices enable permanent in-well sensing for a large-scale role out.

Additionally, a common database has been developed and successfully deployed.

The reservoir engineers in BSP have now full access to the low-cost DTS installed wells around the clock, every day of the year.
