Digital inspection tool for predictive corrosion management

GE Oil & Gas released its Predictive Corrosion Management, the company’s newest digital inspection tool for industrial assets such as refinery pipes, a press release stated. This new asset performance management tool uses embedded sensors to provide continuous inspection data and cloud-based analytics of pipe conditions to help operators manage risk, improve uptime and minimize total cost of operations. Predictive Corrosion Management uses a package of GE’s Rightrax installed ultrasonic sensors with the Predix cloud-based operating system and advisory services to continuously collect and analyze real-time performance data and monitor corrosion-related risk so facilities can proactively make disposition decisions, enabling “digital inspection” of pipes. This continuous inspection tool can identify corrosion before it becomes a problem. It also can improve the reliability of inspection data, remove manual inconsistencies and enable users to model and predict piping failures due to corrosion and erosion, all of which extends the runlife of pipes and other fixed assets.

Diversion stimulation service maximizes wellbore coverage

Schlumberger has released its OpenPath Sequence diversion stimulation service, a press release stated. The new service sequentially diverts acid into additional clusters or zones to maximize wellbore coverage, resulting in more precise treatment placement and greater production when compared to conventional methods. OpenPath Sequence service is the first in the industry to use degradable fibers to suspend multimodal particles that enable sequential stimulation of intervals in acid stimulations. Suitable for cased and openhole completions, the service can be used for acid fracturing or matrix stimulations in carbonate reservoirs. The service also is suited for restimulation treatments in mature fields. This acid diversion stimulation service has been tested in reservoirs in the Middle East and in North America, resulting in proven diversion and significantly improved production.

Reservoir characterization software integrates data into maps

CGG GeoSoftware has released a new version of its HampsonRussell reservoir characterization software, with new features for attribute extraction and prediction along horizontal wells as well as upgraded geostatistical mapping capabilities, according to the company. HampsonRussell 10.2 provides better workflows for greater productivity with new data conditioning, inversion and map prediction features. Key features include new data conditioning processes, residual normal moveout correction and FXY deconvolution for noise attenuation and spectral balancing. Inversion can now output relative impedances for both pre- and post-stack data and extract attributes along horizontal well paths. This new information helps users mine and interpret data from derived attributes, resulting in more accurate reservoir models. The new MapPredict application is a fully integrated easy-to-use map-based geostatistical software that integrates well, seismic and attribute data into accurate, detailed maps. MapPredict encompasses the functionality of HampsonRussell’s former ISMap application and has evolved to include the ability to handle horizontal wells. MapPredict is especially suited to finding relationships between multiple seismic attribute slices and properties derived from well information such as hydrocarbon production.

Drillship design reduces development building and operating costs

The Scylax, designed by GustoMSC, makes development of the mid-water to deepwater market available with reduced building and operating costs by providing fit-for-purpose capabilities, a press release stated. The key is to focus on the essential functionality for deepwater drilling. Whereas ultradeepwater units feature ever-increasing hookloads and capacities, these requirements can be reduced for a large amount of the wells in deep water. Designing the Scylax based on these rationalized requirements allows different choices to be made in the design, reducing building and operating costs. Designed around the drilling process, the Scylax provides deepwater drilling in a compact design based on a single derrick or drilling mast setup with offl ine stand building, dual BOPs, up to 3,048 m (10,000 ft) water depth capability and ample capacity mud systems. Drilling equipment packages of all major manufacturers can be readily integrated into the design.

Software for optimization

AspenTech has released its aspenONE engineering and aspenONE manufacturing and supply chain version 9.1 software, a press release stated. The latest software release gives users the ability to conduct systemwide optimization and debottleneck the entire LNG process, which offers significant opportunity for energy savings and avoidance of unplanned downtime. Improvements to the piping and instrumentation diagram editor improve ease of use and the accuracy of estimates by refl ecting engineering designs earlier, reducing capex risk. The software update includes the new Aspen Coil Wound Exchanger, integrated with Aspen HYSYS software to complete the solution for rigorous modeling of all cryogenic heat exchangers used in LNG applications at the equipment and process level. Additionally, Aspen- Tech released a new product suite, aspenONE Asset Performance Management (APM). The suite expands the aspenONE product portfolio from engineering, manufacturing and supply chain into maintenance to address key business challenges that include process disruptions, low asset availability and unplanned downtime. The aspenONE APM suite will enable companies to optimize their assets throughout the entire plant life cycle.
