Spear performs multiple cut and pull operations in one trip

The Harpoon cut and pull spear from Baker Hughes is designed for casing removal during plug and abandonment and slot recovery operations. The spear can be set and reset several times, enabling multiple cut and pull attempts in a single trip. This increases the likelihood of retrieving the casing in one run, improving efficiency and reducing costs. The ability to reset the spear is advantageous in situations where cement stringers, scale buildup and other downhole factors can make pulling the casing at the initial cut point very difficult. The spear is run with a cutting assembly and does not require a stop ring, which allows the spear to engage the casing directly above the cut and ensure maximum force is distributed at the cut point. The tool reduces nonproductive time associated with additional trips and increases the overall efficiency, safety and economics of casing removal, the company said in a product announcement. bakerhughes.com/harpoon

Slim hanger expands limits of where gauges can be placed in wellbore

Peak Well Systems’ Hi-Ex Gauge Hanger allows the slickline deployment of data acquisition devices through narrow constrictions in the well, expanding the envelope of where gauges can be positioned within a wellbore, according to a company news release. The slim but expandable design of the hanger minimizes flow restriction so that operators can record accurate data during production or injection conditions. The tool is deployed to suspend data acquisition gauges during well testing and production monitoring and also can be used as an anchoring platform in nonmonobore wells. The Hi-Ex Gauge Hanger is deployed from surface using Peak’s eSetting Tool. At the required depth in the well, the eSetting Tool activates and sets the hanger, expanding its arms and centralizing it in the tubing. The hanger is securely anchored in the well via bidirectional slips. It is retrieved using an external fishing neck pulling tool along with any gauges that may have been deployed. peakwellsystems.com

Gauge allows measurements from one side on internally corroded pipes
The 27MG Ultrasonic Thickness Gauge from Olympus is designed to make accurate measurements from one side on internally corroded or eroded metal pipes and structures, a company press release said. It is made for inspectors and maintenance engineers who need to monitor the wall thickness in metal pipes, tanks, beams and structural supports that are susceptible to corrosion on the inside surface. The ultrasonic gauge saves time and cost by transmitting sound into the material from the outside without needing to damage the part. The tool has many measurement features that are available on more advanced-thickness gauges despite weighing only 12 oz. and being easily operated with one hand. The battery-operated gauge features a large backlit LCD and a color-coded keypad with direct access to many features. Standard features include automatic probe recognition to optimize transducer performance, auto zero compensation for accurate measurements on hot surfaces, gain adjust to improve measurement on sound-attenuating materials and differential mode. olympus-ims.com

Printers aid analysis in harsh environments without extra supplies

The Printrex 920 and Printrex 980 color printers are useful to oil and gas companies for addressing the complexities of analyzing both seismic data and oil wells during all phases of exploration and production, TransAct Technologies Inc. said in a press release. The Printrex 920 was developed specifically for use in the oil field. The clear and detailed printouts from the machine show important information allowing accurate, real-time analysis and decision-making at the well site. The printer also is designed to withstand the harsh environments of remote locations. The 920 uses thermal technology allowing it to print in color and black and white without ink cartridges or ribbons so no supplies are needed. The Printrex 980 color office printer is a full-color inkjet printer with the ability to print continuous well logs at the rate of 8 in. per second. transact-tech.com

Leak detector features industry’s first ANN intelligent drive

Designed with artificial neural network (ANN) intelligence and real-time broadband acoustic sound-processing technology, the Gassonic Observer-I Ultrasonic Gas Leak Detector provides ultrasonic gas leak detection with suppression of false alarms. Its applications include FPSO vessels, petrochemical refining plants, gas/hydrogen storage facilities, gas compressor stations, LNG/GTL trains and LNG regasification plants. The ANN technology makes it possible to fully analyze the sound spectrum down to 12 kHz, and its algorithm has been “trained” to automatically distinguish between unwanted acoustic background noise and dangerous gas leaks. This design provides a broader leak detection range, which also increases sensitivity to smaller gas leaks without interference from unwanted background noise. The technology also enables the detector to be installed without time-consuming “training” sequences and provides a detection distance up to 28 m (92 ft). gassonic.com

Ruggedized DTS designed for remote, hostile environments

Silixa Ltd. released the XT-DTS, a high-performance ruggedized distributed temperature sensor (DTS) for remote and hostile environments, the company said. The unit collects extremely fine-resolution data over an operating temperature range of -40 C to 65 C (-40 F to 149 F). The XT-DTS is part of the company’s Ultima DTS family and is a low-power DC-operated sensing unit that offers a new level of insight into previous unobtainable data collected in very harsh environments. The system can be configured and controlled remotely via a wireless or satellite link, enabling remote data collection. The DTS also contains a self-calibrating utility and onboard solid-state storage. The unit comes with four channels with a sampling resolution of 25 cm and spatial resolution of 60 cm over a measurement length of up to 10 km (6.2 miles). It has a minimum measurement time of 5 seconds. silixa.com

Technique rids data of remnant marine-diffracted multiples

Geotrace Technologies has developed Targeted Apex Shifted Elimination Routine, or TASER, a post-surface related multiple elimination (SRME) technique that eliminates remnant diffracted multiples from marine data, the company said. SRME is a powerful, time-proven 3-D process to eliminate multiples appearing in marine acquisition. However, despite the strength and generality of standard SRME methods, there are situations where they are unable to completely eliminate these spurious reflections. One such situation appears when there are strong diffracted multiples. The nonspecular nature of the diffracted multiples makes it hard for SRME to eliminate them. This new technique is based on the realization that diffractions have special kinematical characteristics that can be exploited to separate them from the primaries and eliminate them. geotrace.com
