DTS support for Steam Assisted Gravity Drainage (SAGD)

Accurate, continual, and real-time temperature reading along the well path can give you valuable information about the condition of both the reservoir and downhole completion provided by LIOS distributed temperature sensing (DTS). This enables you to adjust parameters and schedule maintenance for maximum hydrocarbon production and minimize downtime.

DTS Temperature readings allow you to:

• Enhance oil and gas recovery
• Increase production yields
• Track well production changes over time
• Reduce frequency of well interventions
• Improve reservoir management strategies
• Supply in-flow distribution along the reservoir
• Detect early water, steam (SAGD), or gas breakthrough and its location
• Observe steam flooding performance
• Verify and allocate cross flow
• Determine skin factor
• Check integrity of casing and completion
• Monitor and optimize gas lift valve operation
• Detect stuck or leaky valves, perforation inflow, porous insulation, wax deposits, hydrate precipitation, etc.

Setting Standards for Highly Reliable DTS Performance

LIOS Technology GmbH is the leading manufacturer of industrial DTS systems with an impressive track record of more than 2000 installations in permanent operation. Its current DTS product series was carefully designed and thoroughly tested targeting reliable performance and smooth operation in industrial environments.
This was imposingly endorsed by the latest statistical field analysis in respect of a mean time between failures (MTBF) evaluation. Adapted from field data of our installed base of the current DTS product series an excellent MTBF figure of 28 years was reached.

High reliability is also a result of the unique optical frequency-domain reflectometry (OFDR) technology of the LIOS DTS systems. In contrast to time-domain technology using pulsed lasers with high peak powers, the LIOS OFDR DTS uses a quasi-continuous laser with low peak power resulting in a nonexistent wear out of the laser unit or any other fatigue of other optical components. The exceptional reliability favors the deployment of the LIOS DTS systems in all remote, safety-relevant and industrial applications.

Success story for permanent downhole sensing - Maximize your ROI with DTS

Technology is the key driver in the quest for greater efficiency. 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.”

Lt Col (B) Mahmod Yakop (Founder & Managing Director, AMRTUR Corporation Sdn. Bhd)

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 temperature sensing have been successfully demonstrated in a number of recently deployed on- 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.
