Broadband vibrator aids in recording extra-low frequency bandwidth

Sercel’s new broadband vibrator, the Nomad 65 Neo, has enhanced mechanical and hydraulic components and shaker redesign to open up new prospects for broadband land seismic acquisition, the company said in a press release. The Neo is an evolution of the Nomad 65. The vibrator brings down the sweep start’s frequency at full drive from 7 Hz to 5.4 Hz, so the time spent emitting the very low frequencies from 1 Hz is significantly reduced. It facilitates the recording of an extra-low frequency bandwidth that has proved beneficial for vertical resolution and seismic inversion, the release said. The vibrator’s intelligent power management feature—onboard software technology—reduces environmental impact by performing an electronic control and regulation of the vibrator engine’s rpm to match engine load, allowing for fuel savings. sercel.com

Modular leak detection system adapts to variety of monitoring tasks

The Modular Subsea Monitoring Network (MSM) from Kongsberg Maritime is a system that offers continuous monitoring of the subsea environment and alerting of events such as oil and gas leakages from subsea installation, pipelines and risers. The MSM is built on Kongsberg technology including the cNODE for underwater acoustic positions and data link, a range of hydroacoustic sensors, chemical sensors and hydrocarbon sniffers. Advanced data processing and power management strategies ensure MSM’s ability to deliver sensor data continuously for long-duration missions. The modularity and scalability of the MSM allows for easy deployment and adaptation to different monitoring tasks ranging from very early leak detection and condition monitoring around subsea structures to environmental monitoring on the seabed and in the water column. km.kongsberg.com

Housing helps clamp-on flowmeter withstand harsh environments

The new KATflow 170 flowmeter from Katronic is a clamp-on flowmeter designed around a choice of pressure-encapsulated housings in corrosion-resistant materials manufactured to withstand harsh environmental conditions protecting the long-term integrity of the transmitter and continued reliable measurement. The soundness of the housing is maintained since the enclosure doesn’t need to be opened when programming and commissioning the flowmeter. All commands are entered through the glass-fronted keypad using a magnetic pen. The meter’s encapsulated IP68 transducers are manufactured from stainless steel with a cable conduit for further reliability. The measurement system is ATEX-certified for hazardous area zones 1 and 2. Since the transducers are just clamped onto the external surface of a pipe, the flowmeters are ready for operation in minutes. KATflow meters use a precisely matched pair of sensor heads to send and receive ultrasonic signals with and against the direction of flow, which are evaluated and processed by Katronic’s software and algorithms to calculate the flow velocity and volumetric flow rate. katronic.co.uk

Manifold automatically maintains well tubing pressure during operations

The Generation III Remote-Controlled Frac Manifold from Concentric Pipe and Tool Rentals LLC consists of an Accu-Choke remote panel for operators to safely interface with the choke manifold skid. This manifold choking system automatically keeps the well tubing pressure at the desired level during well gravel-packing and fracturing operations, the company said in a press release. The primary system controls are a touchscreen and programmable logic controller for automated operation, changing system setpoints, data entry, reviews and control of the whole system using visual graphical controls. The Accu-Choke system is electronically operated automatically and has backup pneumatic manual controls. The Generation III is rated for use in the Gulf of Mexico and internationally, and it is constructed for corrosion-resistant operations including direct sunlight with intermittent sprayed salt water, temperatures of -7 C to 38 C (20 F to 100 F) and 100% humidity. concentricpipe.com

Well testing system provides acoustic control of tools, real-time data

Halliburton introduced its RezConnect Well Testing System for wireless control of downhole drillstem test (DST) tools, measurement and analysis of well test data in real time. Previously, control of DST tools was done through annulus pressure manipulation. The system uses the DynaLink Telemetry System, a wireless downhole sensor and actuator network using acoustic energy in the tubing string. The RezConnect system integrates all of the DST tools and allows surface verification of their operational status. It also provides acoustic control of DST tools and actuation of downhole fluid samplers, and it collects real-time well flow measurement and bottomhole pressure and temperature data for reservoir performance monitoring and analysis. When used on a deepwater well in Latin America, the system optimized the duration of the well test flow and pressure buildup periods and confirmed the need for acid stimulation. This allowed improved well productivity and the ability to evaluate post-stimulation well performance, ultimately resulting in rig time savings of five days. This was the first fully acoustic telemetry-controlled and -monitored real-time deepwater DST. halliburton.com

Next-generation compound offers improved strength, impact resistance

Luvocom SCF is a new generation of high-strength, impact-resistant compound for structural metal replacement from Lehvoss North America. Based on polymers such as PA 6, PA 66, PA 46 and PPA and reinforced with carbon fibers, the Luvocom SCF product range outperforms traditional carbon fiber compounds, according to a Lehvoss product announcement. The compound has higher tensile strength and stiffness than traditional carbon fiber-reinforced polymers as well as improved impact resistance. Because of its lower specific gravity, Luvocom SCF is lighter than metal- or glass-reinforced polymers. It also has good tribological properties, is electrically conductive and has low coefficient of thermal expansion. Applications for the compound include engineered components in oil and gas and industrial markets, the release said, such as dynamic parts in pumps and compressors. The compound offers weight reduction and the associated energy savings. luvocom.com

Pressure switches provide enhanced durability, reliability

Honeywell Sensing and Control added three new series to its pressure switch portfolio—the HP Series, HE Series and LE Series. The new switches provide high-burst pressure ranges, a long life-cycle rating and IP67 sealing to enhance durability and reliability. High-burst pressure and up to 2 million life-cycle ratings allow the switch to operate in demanding applications, help protect critical systems and reduce end-user downtime. The IP67 sealing prevents water ingress from causing the switch to fail. The pressure switches provide a wide temperature range of -40 C to 120 C (-40 F to 248 F) and accuracy of ±2%. The electromechanical gauge pressure on/off switches are available with either single-pole single-throw normally open or normally closed circuitry or single-pole double-throw circuitry. sensing.honeywell.com
