PDC bits for steerable motors
 A new line of PDC bits optimized for steerable motor applications has been introduced by Hughes Christensen, a division of Baker Hughes Inc. Genesis HCM bits offer both longevity and penetration rates comparable to traditional PDC bits, but with the control and precision of a roller cone bit. Using EZSteer depth-of-cut control technology, the bits have bearing surfaces near the center of the bit face that are designed to engage the hole bottom in slide mode, but not in rotate mode. This tempers aggressiveness when steering but preserves ROP while rotating. Other features include optimized CFD hydraulics and enhanced stabilization, enabling the bits to drill a smooth wellbore at high ROP. (Hughes Christensen)
Landing string control system
A new control system designed to enhance the latest generation of landing string technology for completion and intervention operations has been introduced. Called Express7, the system is designed for use in deep or ultra-deep waters and, combined with Expro’s Enhanced Landing String Assembly (ELSA), provides operators with a high-reliability/high-integrity solution for completing deepwater subsea wells. The system uses the simplex or direct electrohydraulic control method, but also deploys the features and benefits of multiplex technology for data acquisition. There is no requirement for subsea electronics or power supply. Other advantages include reliability, lower deployment costs, retention of hydraulic backup via pilot lines, and independent data acquisition/project interchangeability, since there is no need for custom-made control software. Express7 allows for downhole storage of control fluid for subsea valves, which ensures the system can achieve shut-in or closure and disconnect within 15 seconds. It is designed to operate in water depths to 10,000 ft. (Expro International Group)
Reset relief valve
RR Valve Inc. has introduced a “real-world” re-set valve for oilfield applications that reduces downtime. The valve weighs 119 lb and can be serviced by one person. Utilizing advanced metallurgical engineering, advanced design modeling and computer-aided design, the valve has been extensively tested for reliability. Test results, product guides and complete documentation are available from the manufacturer. (RR Valve Inc.)
3D visualization facilities
 Paradigm has introduced its new, state-of-the-art Visionarium in Houston. Offering stereoscopic vision and advanced control facilities, it has already seen extensive use by oil and gas professionals for software demonstrations and integrated service project reviews, as well as for industry events. It provides stereoscopic, large-scale displays on the critical details of seismic, reservoir and drilling features of a project for making practical and timely E&P decisions. The facility combines the Voxel rendering engine with the 3D horizon autotracker and fully integrated reservoir navigator, and includes a panoramic, 18-ft-wide, rear-lighted screen from Mechdyne, with edge-blended Christie Mirage 4000 projectors. It is located in a special facility at Paradigm’s Houston offices. (Paradigm)
Downhole pump drive head
The Moyno Ultra-Drive Model CV1 is an electrically driven drive head that offers rugged construction and numerous operational features for medium-duty progressive cavity pumps. The product features polished rod speeds to 600 rpm and a 1,600 ft-lb torque rating on its recoil braking system. Its low profile design simplifies field mounting and installation, and a removable sealing system permits flexibility and ease of service. The Model CV1 can accommodate 1-1/4-in. or 1-1/2-in. polished rods. (R&M Energy Systems)
Clean water surfaces
 SASSI, an environmental vessel designed to clean waterways, riverfronts or lakes, is now available. The sweeper is 27 ft 8 in. long, and extends its wings for a 50-ft-wide sweep to clean trash and impurities from the water surface. The vessel aerates the water during operation, and doesn’t disturb the waterway floor. Each wing has six replaceable nets to collect and contain contaminants and debris. Options include a system to clean up oil spills and other hazardous waste. (SASSI)
Subsea detector
AnTech Ltd has introduced a subsea multi-directional edge tracing (MDET) detector system, which not only assists deepwater operators in positioning special equipment, but detects the end of coiled tubing inside a riser. The system makes it possible to effectively “see through” steel tubulars by way of a remote audible and visible warning system, making equipment positioning a more controlled, precise process. An added benefit is that the sensors clamp to the outside of the riser, so they don’t interfere with other equipment or other activities being carried out on the seabed. The sensor is strapped to the riser from the wellhead, where it detects the passing of a magnetic marker, relaying that information to the control room, and giving both an audible and visual signal to the operators. This allows equipment to be positioned inside the riser with an accuracy of a few inches. (AnTech)
