TGT Diagnostics has unveiled Octasense, one of the industry's first integrated well and reservoir diagnostic platforms that delivers eight critical insights in just one descent.

The tool, launched at ADIPEC 2025, is said to cut rig time in half along with more production, less risk, fewer emissions and lower costs.

It also cuts diagnostic time per well from over 50 hours to 16, while capturing crucial data that previously required multiple logging operations.

Replacing multiple runs with a single run saves an estimated 48,000-106,000 kgCO₂e per offshore workover, the equivalent of removing hundreds of cars from the road for every campaign.

Traditional well integrity and reservoir diagnostics require multiple descents with different tools, each adding rig time.

However, Octasense needs one, while its AI-driven analysis delivers preliminary results in hours, not weeks.

A single descent captures insights on borehole flow, reservoir flow, barrier isolation, sand production, leak detection, corrosion monitoring, fracture characterisation, and completion performance, providing a complete and integrated view of well and reservoir behaviour.

This means operators can detect leaks, corrosion, and barrier failures before they force costly production shutdowns, with complete visibility of flow dynamics inside and behind casing. 

Teams can then plan interventions with confidence, validate repairs with certainty, and support plug and abandonment (P&A) and carbon storage decisions with proven integrity data.

CASE STUDY

An early deployment in North America saved two logging days per well, reducing costs by around $100,000 per well, and potentially $2 million per campaign.

A mature well showed integrity failure and suspected fluid movement. Previous isolation attempts had failed.

The traditional approach meant multiple surveys over several weeks. Octasense completed everything in one daytime run.

The integrated platform identified multiple shallow leaks and dual flow inside and behind the casing. 

It mapped significant production casing corrosion and moderate intermediate degradation. 

Leaks that single sensors miss were caught immediately because the eight-sensor platform worked as one. 

As a result, the operator switched from wellbore plug to rock-to-rock abandonment. One descent instead of multiple operations saved an estimated $40,000 per day based on the spread rate. 

The technology addresses regional operational priorities including reducing rig time, shortening turnaround windows, and cutting emissions. It also aligns with ADIPEC 2025's theme of Energy. Intelligence. Impact.

"Until now, operators have faced many challenging trade-offs. Decisions to either spend more time and money on complete diagnostics, or spend less on quicker results but with less certainty. Octasense solves this dilemma," says Julian Martin-Gaubeca, CEO, TGT Diagnostics. 

He adds: "We give operators the complete well integrity and reservoir performance picture in hours. That means faster decisions, valuable information they can act on, and the well keeps producing.”

“Octasense isn’t just a step forward in diagnostics — it’s a leap in efficiency, certainty, and sustainability,” added Ehab Shalaby, Vice President – Global Sales & Marketing, TGT Diagnostics.

“By integrating eight measurements into one platform, we’re helping operators cut rig time, reduce emissions, and make faster, smarter decisions. Launching it from our new UAE technology hub reinforces our commitment to ‘Make it in the Emirates’ while serving global operations.”
