Fotech delivers unrivalled in-well monitoring and imaging with Helios Theta

As operators increasingly turn to Big Data for new insights into their operations, Fotech has launched Helios Theta – its most advanced Distributed Acoustic Sensor (DAS) product, optimised for upstream operations. Helios Theta provides fine-grained data on well performance during a range of operational scenarios such as Vertical Seismic Profiling (VSP). This new layer of intelligence will enable operators to extend the life of wells, realise new operational efficiencies and increase production.

Based on Fotech’s True Phase technology, making use of cutting-edge photonics, edge computing, and advanced AI systems, Helios Theta delivers greater fidelity, enhanced sensitivity and superior flexibility in the field. This improved performance enables the detection of smaller microseismic events and lower levels of fluid and sand production – giving operators far more detailed insights into well performance.

Helios Theta also allows the acquisition of seismic data at greater well depths than ever before. Whereas typical upstream DAS solutions have a sensing range around 10km, Helios Theta offers detailed measurement and imaging to well depths of up to 40km from one sensor unit.

Three distinct detection modes give operators the ability to dynamically optimise Helios Theta for the specific conditions of each downhole operation. Two quantitative phase modes (Bandwidth and Fidelity) enable high quality imaging for low energy environment applications, ideal for VSP and microseismic measurements. A third ‘intensity’ mode provides unmatched performance and profiling for high energy environments, for example during hydraulic fracture operations.

Chris Shannon, CEO, Fotech Solutions, said: “Helios Theta is the latest in a long line of products from Fotech that push the boundaries of innovation in upstream applications. DAS has been vital in helping operators move into an operating model of continuous improvement in the field. In return, we must continue to innovate as the demand for more and better data grows ever-greater.

“Now the technological advancements of Helios Theta and its in-field versatility will provide another step change in operators’ ability to understand the economics of their well, to help move the breakeven point, and ultimately to realise new efficiencies and new revenues.”
