Faster. Consistent. Scalable. How AI is transforming lithofacies interpretation

Lithofacies interpretation remains one of the most fundamental tasks in subsurface evaluation – and one of the most time-intensive. Despite advances in logging technology and computing power, workflows are still dominated by manual interpretation, subjective judgement and inevitable variability between interpreters. When dozens or hundreds of wells must be assessed, particularly in early-stage screening or regional studies, this inconsistency can delay decisions around reservoir presence, interval ranking and further petrophysical review.

A new deep-learning workflow developed at DUG demonstrates how that bottleneck can be significantly reduced – delivering fast, reproducible lithofacies predictions directly from standard wireline logs. Rather than replacing geological interpretation, the approach provides a consistent first-pass screening tool that allows interpreters to focus attention where it adds the most value.

A key differentiator of the workflow is its foundation in rock physics. Any supervised machine-learning model is only as reliable as its training labels, and in this case those labels are derived from carefully curated end-member lithologies. These end members represent the cleanest and most internally consistent examples of sandstones, shales, siltstones and carbonates, selected only where wireline responses align physically and geologically. By excluding intervals affected by poor borehole conditions or noisy measurements, the resulting training dataset remains objective, consistent and firmly grounded in established rock physics relationships.

The model architecture combines a transformer-based sequence model with a one-dimensional convolutional neural network, also previously developed by DUG. This enables it to capture both long-range stratigraphic trends and local log-response variability, while handling missing data through attention masking. Crucially, the workflow accepts whichever subset of common wireline curves is available for a given well, allowing lithofacies prediction even in older or incomplete datasets.

Case studies using legacy data illustrate how DUG’s workflow delivers insight beyond speed alone. Artificial intelligence (AI)-generated lithofacies predictions highlighted subtle inconsistencies caused by density spiking and sonic cycle skipping – issues that were not immediately apparent in conventional single-well analysis. By flagging these intervals, the workflow guided targeted quality control and conditional correction, improving multi-well correlation without introducing artificial geological trends.

Rather than obscuring interpretation, DUG’s workflow makes inconsistencies visible – highlighting where log behaviour departs from rock physics expectations and directing interpreter attention where it is most needed.

This work will be presented by DUG’s machine learning software engineer, Kyle Rosa, at the SEG | DGS | SPE KSA Workshop: Bridging the Gap: Geosciences to Engineering in Al Khobar, Saudi Arabia, from 10–12 February 2026.

As geoscience datasets continue to grow in size and complexity, AI-augmented interpretation workflows help enable faster, more consistent subsurface decisions – without removing the interpreter from the decision-making loop.

GPT Industries’ Iso-Smart remote pipeline monitoring device has attracted a high level of interest from operators in the Middle East since it was introduced to the region around a year ago

Iso-Smart is an all-in-one solution for checking Cathodic Protection (on and instant off potentials), Isolation, Bond currents, AC vs. DC on the line, and more from remote locations. The device can be mounted at any current test station along a pipeline, and incorporates True RMS technology to provide reliable real-time data, helping pipeline owners make informed decisions, address any issues or anomalies before they become critical and comply with pipeline integrity regulations. Combining GPT Industries’ decades of corrosion prevention expertise with the latest remote monitoring technology, it sets a new standard for a versatile, user-friendly remote asset integrity monitoring.

Iso-Smart communicates readings instantly to a secure dashboard, giving operators real-time visibility into asset performance. The platform also supports customisable alerts, automated reporting, and over-the-air firmware updates.

Speaking to Oil Review Middle East at ADIPEC, Michael Monica, director global sales, marketing and customer care at GPT Industries says that the company has successfully piloted Iso-Smart with end users in the region. The pilot is now validated and approved, the next step being to reach out to more end-users.

“The biggest differentiator with this device is that it is able to determine AC density on pipelines, something that is unique to Iso-Smart,” Monica points out. Pipelines exposed to alternating current (AC) from nearby power lines or railways face serious risks, including accelerated corrosion, compromised cathodic protection and safety hazards.

“Iso-Smart can distinguish direct current from alternating current, which is something operators need to be able to determine, and ensures your CP system is at the right level to protect the asset. The big advantage is that it allows you to remotely monitor the asset in real time from a dashboard, eliminating the need to take physical readings at the site. You can tell it you want it to measure, and how often.”

Monica emphasises the importance of Iso-Smart for compliance, noting its real-time monitoring capabilities and the ease of generating reports.

The latest version of Iso-Smart, launched a few months ago, incorporates significant new enhancements, based on end-user feedback, notably a more compact housing designed to fit seamlessly within standard three-inch test stations, making installation simpler, faster, and more practical for new and existing field operations.

Monica goes on to discuss the company’s takeover of Integrated Rectifier Technologies( IRT), a Canada-based manufacturer of transformer rectifiers and related products for the cathodic protection (CP) industry with a strong and established presence in the Middle East and globally.

This strategic acquisition unites GPT’s expertise in flange isolation technology and remote asset monitoring with IRT’s long-standing reputation for reliable rectifier systems, further strengthening GPT’s role in helping operators mitigate corrosion and maintain asset integrity across energy and infrastructure sectors.

Integrating IRT’s rectifier technology with GPT’s Iso-Smart remote monitoring platform will accelerate the development of advanced remote asset integrity systems, providing operators with deeper visibility into CP performance, streamlined data collection and faster response to field issues.

“We’re really excited to be working with IRT,” says Monica. “This acquisition expands our strategy of protecting our customers’ assets in the area of cathodic protection.”
