Tendeka has been awarded a two-year multi million dollar contract extension from Total E&P Qatar to supply its industry-leading Sentinel distributed temperature sensing (DTS) system and its FloQuest? interpretation services on the Al Khalij oilfield, offshore Qatar.

The extension follows on from an initial three-year contract agreed for the scope of work. The field uses waterflood secondary recovery to produce oil through horizontal wells. Information from Tendeka's Sentinel DTS system, which has the required level of temperature measurement resolution (less than 0.01 degree Celsuis), enables the interpretation of flow distribution and allocation of the different pay zones using FloQuest in the producer wells, in addition to detecting water breakthrough.

Similarly, the permeable zones and flow distribution are able to be interpreted in the water injection wells.

The integrated deployment of DTS and FloQuest provide a complete temperature profile of the wells, enabling the operator to optimise performance.

Data is continuously available in real-time providing enhanced understanding of flow contribution and immediate detection of water breakthrough.

Gary Smart, chief operating officer for Tendeka, said, 'We are delighted to have been awarded this significant extension to our original contract and look forward to working with the operator in future. The effective combination of our Sentinel DTS system and our FloQuest interpretation and modelling technology have produced excellent results for our client and represent another step toward Tendeka providing integrated production optimisation solutions.'

Jean-Francois Authier of Total E&P Qatar said, 'Total E&P Qatar is pleased to award Tendeka the renewal of the DTS contract for the next two years. This confirms our confidence in the work done since 2006 with Tendeka on the Al Khalij field.

'The DTS was installed successfully on three new horizontal wells with implementation of real time acquisition systems to allow a direct monitoring of temperature on these crucial wells, in particular to detect possible water entry along the completed drain.

'Total E&P Qatar looks forward to working closely on this project with Tendeka in the future.'
