PC pump drivehead
The Moyno Ultra-Drive Model A30 drivehead from R&M Energy Systems provides reliable performance and long service life for downhole PC pumping systems. The A30 is completely compatible with Moyno downhole pump systems for both crude oil extraction and gas well dewatering applications. The drivehead has superior dynamic wellhead sealing capability, is easy to install, has safe and consistent recoil control during shutdown and a low profile design. It accommodates 11/4-in. polished rods. The motor support frame is designed to accept electric motors up to 30 hp. Power is applied through a vertical input shaft in the drivehead. Other features and benefits include a hollow shaft design that allows for simple rotor space out, single-point belt tension, hydraulic brake system for controlled recoil, removable stuffing box and a two-piece hinged belt guard for rapid sheave access.
Rugged CO2 meter The ST75 flow meter from Fluid Components International (FCI) provides precise direct mass flow measurement of gases in an insertion-style instrument that requires almost no maintenance over a long life. The meter is ideal for the measurement of CO2, which is commonly recovered from natural gas wells, and is also used to enhance production from older oil wells. The ST75 is a rugged, reliable instrument suitable for demanding environments. Designed for line sizes from 0.25 to 2.0 in. (6 to 51 mm), the ST75 provides three outputs: mass flowrate, totalized flow and media temperature. With accuracy to ±1% of reading and ±0.5% repeatability, the meter’s design includes media temperature compensation to ensure performance under variable temperature conditions. Its flow element is designed with no moving parts. It employs platinum RTD sensors embedded in equal mass thermowells with microprocessor electronics that can be calibrated to laboratory standards for CO2 as well as many other gases. The ST75 Flow Meter operates over a wide flow range, from 0.01 to 559 scfm depending on line size, making it suited for both low-flow and high-flow applications.
CCTV for hazardous areas
R. Stahl has introduced a scalable package of camera and recording system for surveillance in hazardous areas on gas and oil rigs. In addition to making operations safer, it enables users to carry out a thorough study of causes and fix any problems in the case of incidents. The system supports both live monitoring at HMI stations as well as complete documentation of events. The standard package includes four cameras whose video signals can be recorded manipulation-proof for up to 10 days, and also permits authorized remote access to images via the internet. It can be expanded to include up to four times the number of cameras, and the standard 500 GB recording capacity can be expanded to meet specific application requirements. Resolutions of up to 704 × 576 at full PAL format can be selected for the H.264 compressed digital video files. A pan/tilt/zoom control module is available for the remote control of the cameras. With a diameter of only 55 mm and 435 grams, the cameras can be fit into very small spaces. The fixed viewing angle is ±90° horizontally and 68° vertically.
Extended-life drilling motor
Mpact Downhole Motors has introduced the model 775 7822 HTS drilling motor. The motor features the Mpact 114 stator elastomer, which outperforms NBR and HNBR elastomers with extended life expectancy of over 4:1 and a significant increase in performance and reliability. This 7¾-in. drilling motor is an ultra-slow-speed design (0.08 revolutions per gallon), delivering more than 15,000 ft-lb of torque at 489-psi differential pressure. With a maximum power rating of 192 hp, it has a flow range of 300–900 gpm.
Medium-pressure ball valves Swagelok has released a larger size of its FKB series medium-pressure ball valve. Designed for improved cycle life in the field, the trunnion-style ball valves provide a leak-tight seal for applications up to 15,000 psig (1,034 bar) and feature the direct-load design, which delivers a consistent seal across a full range of pressures. Stem and end connection seals prevent shell leakage and provide robust cycle life in severe conditions. The two-way 8FKB ball valve complements the original 6FKB ball valve introduced in 2009. The 8FKB, with a 0.375-in. (9.52-mm) orifice, offers ½-in. gaugeable medium-pressure tube fitting end connections or ½-in. female NPT. All valves feature 316 stainless steel body construction, and reinforced PEEK seat seals. They are rated for temperatures from 0° to 250°F, and maintain a full pressure rating throughout the entire operating temperature range. Multiple o-ring materials are available, including nitrile, fluoroelastomer and perfluoroelastomer.
Underreaming tool
Allamon Tool Co. has introduced the Commander underreamer for wellbore enlargement. The tool is designed for robust applications and weak bottomhole formations. It is the only underreamer to provide fully opened cutters to their intended diameter throughout the entire hole section. The cutters are manufactured with PDC material, and the tool’s axial cam assures that the cutters are rigidly supported at the desired cutting diameter. The capped housing design and cutter spacing reduce vibration to the workstring and provide increased torque resistance and stability. It is readily activated with a ball drop.
Infrared flame detector
General Monitors’ Multi-Spectrum Infrared (MSIR) FL4000H flame detector features a new housing for easy installation that simplifies wiring and other set-up tasks. The FL4000H, with its flame sensor incorporating neural network technology, provides reliable flame monitoring with superior false alarm immunity, a wide field of view and a long detection range. An improved design permits cables to be inserted quickly into the base of the unit, which allows the detector to fit in tight corners near ceilings and other structures. The device’s detection algorithm is based on mathematical models that correlate certain patterns of infrared and visible radiation with the incidence of flame. The optical IR sensor array and the neural network function together as an adaptive and intuitive decision-making mechanism, resulting in a reliable scheme for discrimination between actual flames and false alarm sources.
Industrial thermometer protection
Winters Instruments has made the removable Thermowell standard on its industrial 5-in. and 9-in. solar digital and hot water thermometers. Thermowells create sealed systems where temperature measurement can be safely performed. With the media contained, replacement or service of thermometers can be performed without draining or shutting down the system. The Thermowells offer superior protection to thermometers by isolating them from harmful or corrosive media, and also shield the sensitive sensing element from high pressures. For the TBM (bi-metal) series of thermometers, various types of thermowells can be used. Industrial, sanitary, flanged, weld-in, socket-weld and bimetal-type thermo-wells are available.
Ball-activated drilling valve
The Well Commander ball-activated drilling valve from M-I Swaco allows operators to accomplish tasks such as placing lost-circulation material or conditioning or displacing wellbore fluids at high flowrates, while bypassing sensitive downhole bottomhole assembly tools. Generally run in the hole in the closed position, the tool remains inactive until needed. Then the operating ball is dropped and pumped down to the tool. Pressuring up on the ball activates the tool, and the increased pressure unseats the ball, which is expelled into the bypass ball catcher, and the ports are locked open. To close, another ball is dropped, pressure is increased, and the ports are closed as the tool deactivates. The same size operating ball is used to open and close the ports. A smaller BHA-shutoff ball can be dropped to prevent fluid flow or solids deposition at the top of the BHA. Up to seven complete cycles are possible on each trip, since the bypass catcher has a 14-ball capacity. High circulation rates will not cause the tool to function prematurely. The tool can assist in removing cuttings in high-angle/horizontal wells, and can efficiently displace fluids by boosting annular velocities. It also permits easy spotting of coarse lost-circulation material during operations. Other applications include enhanced hole cleaning during hole-opening operations, managed pressure or underbalanced drilling operations, and more efficient pipe filling and draining during trips.
