TGT’s Indigo platform uses real-time technology for oilfield customers

TGTDubai-based oil and gas company TGT has released its real-time Indigo platform which enables well data to be viewed and analysed at surface without compromising on measurement fidelity

Ken Feather, TGT’s chief marketing officer, commented, “Real-time data isn’t new to the oil industry, but currently available transmission systems couldn’t meet our exacting data quality standards. So we developed and built our own high-fidelity system.”

“With this, we have taken conveyance and decision-making flexibility to an entirely new level for our customers, with no compromise on measurement quality. As a result, we expect the popularity of our diagnostic systems and products to expand even further,” Feather added.

The hardware and software are created in-house and the company follows a strict philosophy of ‘fidelity’ in the design and manufacturing of its diagnostic sensor technology and instruments.

This technology is custom-built to operate perfectly with TGT’s through-barrier suite. The real-time capability is relevant to the acoustic-based ‘spectral’ and electromagnetic-based ‘EmPulse’ diagnostic systems.

Through-barrier diagnostics are performed using ‘memory-mode’ deployment. TGT’s memory-mode has a track record of 20-years with an efficiency of more than 99 per cent and it remains a flexible and popular choice across the industry.

Using this approach, diagnostic information is accessed when the measuring instrument is retrieved from the well. However, with real-time access, data can be viewed during the diagnostic intervention and streamed remotely from the wellsite enabling a host of benefits.

Artem Buharaev, TGT’s head of Indigo development, said, “We have overcome many technical challenges in commercialising our real-time Indigo platform. Existing data transmission technology available within our industry generates unacceptable levels of acoustic and electromagnetic (EM) ‘noise,’ that would otherwise degrade our highly-sensitive sound-based and EM-based measurements, so we developed our own design that was both ‘quiet’ and fast.”

The real-time system comprises of a downhole Indigo modem module and a surface interface unit that enables two-way communication between surface recording equipment and the downhole instruments.
