Expanded line of small-bore metric seals

The Timken Co., a provider of bearings and mechanical power transmission products, has released an expanded line of small-bore metric seals, a press release stated. The full line of Timken seals features small- and largebore seals in both inch and metric sizes. The small-bore metric seal range includes sizes from 5 mm to 300 mm with single- and double-lip designs. The company offers small-bore metric seals in both nitrile and fl uoroelastomer materials.

Solution to soil-side corrosion on aboveground storage tanks

Storage tanks used for product storage in industrial facilities are subject to soil-side corrosion during operation, especially when installed in severe environments. There is a growing industrial awareness about the advantage of introducing amine carboxylate vapor phase corrosion inhibitors (VpCIs) into the tank pad. The ability of CorroLogic VpCIs to protect areas that cannot be reached by traditional cathodic protection (CP) makes it an ideal treatment to be used in conjunction with CP or by itself when CP is deficient or absent, a press release stated. Using the power of Cortec’s VpCIs, CorroLogic is able to vaporize and disperse through open areas below an aboveground storage tank (AST). When the VpCIs reach a metal surface, they adsorb and form a protective molecular barrier to guard against corrosion, providing an added dimension of protection to under-tank areas that cannot be reached by CP. Corro- Logic can be added to an AST in several different forms, enabling application during construction of new tanks or while existing tanks are in service or out of service. During construction CorroLogic pouches can be placed on an AST’s high-density polyethylene liner and left to emit VpCIs below the tank surface. If an AST is already in service and needs protection, a CorroLogic slurry is injected beneath the tank floor through the existing monitoring or leakage detection pipes or through injection pipes post-installed through the concrete ring beam. When a tank is out of service, CorroLogic Powder is fogged through the tank floor into the under-tank area and allowed to diffuse.

JIP to improve recovery, profitability of hydraulic fracturing

The Industry Technology Facilitator (ITF), alongside Marathon Oil, Nexen and Repsol, has launched a joint industry project (JIP) to improve the planning, design and implementation of hydraulic fracturing to maximize the efficiency and profitability of unconventional resources globally, a press release stated. The FRACGAS II JIP continues the development of the Elfen tgr (tight gas reservoirs) software suite pioneered by geomechanics software solutions developer Rockfield. The research aims to enhance the finite element-based modeling technology and microseismic methodology. Rockfield CEO John Cain added, “The sponsorship of FRACGAS I enabled Rockfield to deliver a complete product in the shape of Elfen tgr that enables oil and gas operators and service companies alike to model both 2-D and 3-D fracture propagation in tight gas shale reservoirs. The software allows the simulation of the full cycle of stimulation, production, refracturing [and] production operations, including features such as fracture closure, proppant transport and multiwell interference.”

Electro-hydraulic setting tool facilitates safer operations

Probe Holdings Inc.’s electro-hydraulic setting tool, the iSet, is about to perform its first operation in the Middle East. iSet is designed to drive new safety and efficiency standards in well intervention and abandonment operations that require the use of setting tools, a press release stated. With its programmable touchscreen technology, the iSet provides a safe, reliable and costeffective method for setting bridge plugs, packers, gauge hangers and straddles. “Unlike traditional setting tools, the iSet doesn’t require explosive setting charges, so it’s not only safer, but it doesn’t demand special permits to use or transport it, so there are no complex logistics to overcome,” said Neil Duncan, Probe’s regional manager-MENA and Asia. “It also can be run up to 50 times without the need for redressing between runs. On return to surface, the tool can be safely reset in less than 1 minute and ready for the next run within 30 minutes, so it’s extremely efficient.”

Service helps navigate complexities of late-life operations, decommissioning

Lloyd’s Register is offering an integrated portfolio of late-life and decommissioning services to support operators, equity holders and regulators in key territories including the U.K. Continental Shelf, Gulf of Mexico and across Asia in how best to manage their operations productivity with minimal risk and cost-effectively in the run up to cessation of production and decommissioning. The expertise covers subsea operations through to topsides, offshore and onshore technical and engineering solutions, project and data management, assurance, and commercial services.

Technology allows personal monitors to share real-time gas readings

Industrial Scientific has released LENS Wireless technology, which is based on military ad-hoc mesh networking concepts. The technology enables gas monitors to communicate with each other wirelessly with no need for IT setup, infrastructure or a central controller, a press release stated. Industrial Scientific Ventis Pro Series multigas monitors and Radius BZ1 area monitors are available with LENS Wireless. Industrial Scientific is the first manufacturer to enable personal, portable gas monitors to communicate directly with area monitors to share gas readings and alarm conditions. LENS Wireless groups are quick and easy to create, allowing rapid deployment and use in a broad range of applications. LENS Wireless helps workers in any industry respond faster and with real-time information when hazardous conditions occur. When a gas hazard, man-down or panic situation causes an instrument to alarm, all peers in the connected group will instantly be notified of the hazard and the person in danger.
