Geoscientists in the oil and gas industry face many challenges in their quest to de-risk and drill the best wells and more confidently forecast production. CGG GeoSoftware geostatistical seismic reservoir characterisation solutions are powerful allies in successfully tackling these complex subsurface challenges.

Two GeoSoftware solutions, HampsonRussell GeoSI and Jason RockMod, overcome limitations of conventional well-based reservoir modeling. Using seismic inversion, they ensure that the high-resolution model is accurate not only at the wells, but also between them. The limitation of seismic resolution associated with deterministic seismic inversion is lifted because geostatistical methods such as GeoSI and RockMod integrate data at different scales, including well log data. Geoscientists can easily generate multiple plausible realisations that help assess uncertainty in the reservoir model and decide whether to plan a new well location or select scenarios for flow simulation. 

Fully integrated into the HampsonRussell suite, GeoSI is used to perform advanced follow-on studies after deterministic inversion studies with Strata. GeoSI is easy to learn and use, yet powerful and feature-rich. Using seismic angle stacks, GeoSI inverts for P- and S-Impedance and generates multiple realisations of elastic properties using Sequential Gaussian Simulation (SGS). Following this, facies are obtained with Bayesian classification, and facies bodies are extracted from individual realisations. For facies of interest, geoscientists can generate a predicted probability volume and facies volumes at selected quantiles (e.g. P10, P50 and P90) using the multiple high-resolution realisations generated by SGS. Generating a large number of realisations for this process is fast, and a ranking tool based on net pay is included to select the realisations to use in further processing. With GeoSI, you quickly gain insight into the uncertainty in the reservoir. Coming soon, HampsonRussell 10.3 will increase performance on models with large numbers of layers and create facies maps.

Jason RockMod is the most advanced technology for providing reservoir models in corner point grid (CPG) for static and dynamic modeling. Stochastic inversion in RockMod is based on the Markov Chain Monte Carlo (MCMC) algorithm.  Facies distribution within a reservoir is a major source of uncertainty in modeling reservoir properties and flow, and RockMod excels at identifying facies bodies. The multi-level facies modeling tool’s flexibility allows for a complex a priori facies model with geological context. During inversion, facies are simultaneously inverted with elastic and reservoir properties through rock physics models. Facies ‘interpretations’ can therefore be very subtle: bodies do not have to stand out everywhere against their surroundings. Faint or invisible features can be hypothesised and synergies exploited between facies and continuous properties, giving more accurate results. All types of seismic data can be used for the inversion: time or depth seismic (angle or offset stacks) as well as PP-PS, 4D or azimuthal data. 

After generating multiple realisations, the ranking tool helps select realisations for direct transfer, with or without upscaling, to a third-party CPG. Coming soon in Jason 9.7 are a streamlined user interface for 4D, Azimuthal, and PP-PS inversion, and a tool to easily generate multiple scenarios and fully understand all uncertainties associated with the reservoir characterisation project.

Today’s reservoir challenges span relatively simple to highly complex scenarios within a backdrop of limited budget and geoscientific resources. Operators are asking what level of reservoir understanding is good enough to reduce uncertainty to an acceptable level before proceeding with a project.

ControlEdge™ PLC provides powerful enhancements to integration with Experion® 


Honeywell Process Solutions (HPS) announced on 12 June, the newest release of its ControlEdge™ Programmable Logic Controller (PLC). This release, combined with Honeywell’s Experion® distributed control system (DCS), provides a significant reduction in integration efforts and project costs as well as increased security and availability through enhanced cyber security for industrial facilities.

The PLC is used in a variety of balance of plant applications, such as equipment and device level control. It is part of the ControlEdge next generation family of controllers offering unprecedented, secure connectivity through all levels of process and business operations. Experion and ControlEdge PLC leverage a common Human Machine Interface (HMI) platform, provide faster field device commissioning, and improve device diagnostics.

The PLC is being offered to end users, original equipment manufacturers (OEMs), and engineering, procurement and construction (EPC) companies, particularly those in global refining, oil and gas, power, chemical, water management industries, and infrastructure applications.

“Aside from greatly reducing integration costs when combined with Experion, ControlEdge PLC minimizes downtime through unified support, further decreases risk through embedded cyber security, and lowers total cost of ownership through an extended system lifecycle,” said Andrew D’Amelio, vice president and general manager of HPS’ Process Measurement and Control business. “With this newest release, we emphasize our commitment to rapidly evolve this platform to cover more applications and bring additional value to users.”

“Our customers benefit from seamless integration of a DCS with PLC, RTU, field device asset management, and a new HMI panel PC,” said Andrew Brodie, HPS global marketing leader, Controls. “Only Honeywell can serve as a single vendor for all these automation needs.”

ControlEdge PLC provides an IIoT-ready open platform that uses OPC Unified Architecture (UA) as a communication protocol and enables users to better leverage data across their assets. Honeywell’s IIoT portfolio of technologies is bundled in Honeywell Connected Plant, which combines Honeywell’s unmatched industrial expertise, software and cloud technologies to make customers’ operations more reliable, profitable and secure than ever before possible.
