Halliburton has introduced the Intelli suite of diagnostic well intervention wireline logging services, which can help operators benefit from improved well insights, extended asset life, and reduced total cost of operations

The Intelli suite of services can be used separately or as a package. In the latter case, it acquires data in a single run, saving time and costs. The Intelli suite consists of the following services:

The IntelliSat pulsed-neutron logging service provides reservoir insights either in open hole or after a well is completed. It improves recovery with the detection of bypassed pay, and provides spectroscopy and KUTh measurements. The IntelliSat service delivers a more robust and efficient method of reservoir saturation measurement, fluids monitoring, and borehole diagnostics compared to legacy sensors.

The IntelliFlow array production logging service enhances reservoir insights with the incorporation of co-located fluid ID and flow rate sensors. IntelliFlow provides more accurate production profiles, precision phase analysis, and dynamic flow information. The compact design allows for a simpler, more efficient operation.

The IntelliGuard corrosion evaluation service represents the latest generation of high-definition casing inspection technology. It quantifies metal loss in up to seven concentric casings, and pinpoints damage without the need for costly well intervention.

The IntelliScope leak and flow diagnostic service identifies precise leak sources and flow paths vertically and radially behind pipe in a single, continuous pass.

“As customers look to maximise production and improve the efficiency of their wells, our Intelli suite helps improve downhole insights in a highly customisable way. Because each job is unique, we wanted to develop a suite of products that could be used individually, or as an integrated solution, ultimately, delivering a better experience and result for our customers,” said Chris Tevis, vice president of Wireline and Perforating.

Trelleborg Sealing Solutions has launched the Stefa high-pressure radial shaft seal portfolio for demanding applications

Stefa high-pressure radial shaft seals (HPRSS) are optimised to improve sealing performance for various speed, chemical compatibility and pressure challenges. Suitable for various types of hydraulic motors and pumps, Stefa seals are proven at pressures of up to 20MP a and speeds of up to 17 metres per second (MPS). They also feature innovative engineered designs that compensate for shaft misalignment, ensuring reliable sealing under extreme conditions.

The range includes the well-established HP20 series which utilises a patented design geometry that self-balances under strong pressure with a metal retainer that prevents lip extrusion and dissipates heat, extending service life. Millions of the HP20 seals have been sold since its introduction in 2010.

Inderjeet Singh, global product line director, said, “Working closely with our customers and utilising our own advanced manufacturing, R&D and testing facilities, we have delivered a step change in performance and durability with the enhanced Stefa radial shaft sealing range. Equipment that requires high-pressure radial shaft seals is typically complex and high value, and any seal failure will be an expensive liability for the operator.

"Over several years, we have leveraged our advanced global in-house R&D capabilities to optimise geometries and materials to provide customer assurance in terms of performance and durability across a wide range of applications with differing requirements.

"Performance expectations for high pressure radial shaft seals are becoming ever-more challenging, with customers in recent years demanding solutions that work at even high speeds and accelerations. To meet the challenges, we have built advanced test rigs with wider capabilities in terms of operating parameters such as temperature, speed, torque and pressure, as well as pressure spikes and side loads.Trelleborg’s customer proximity has been critical to the successful innovations in our Stefa portfolio, leveraging our materials expertise and design capabilities alongside deep collaboration with customers to provide optimised solutions.”

AERZEN's advanced screw compressors are paving the way for industry decarbonisation

Hydrogen is regarded as the energy carrier of the future, and is a important milestone for the decarbonisation of industry.

As a strong partner to the process industry, AERZEN has been dealing with the topic of hydrogen compression for decades and therefore has a high level of expertise in this field. The compressor specialist's state-of-the-art technologies are in demand worldwide and warrant efficient and safe compression. The VR and VMY series screw compressors have proven particularly successful in this regard.

Hydrogen is the lightest element present, which makes compression fundamentally more difficult. As it has a very low energy density in relation to the volume flow (energy content per volume unit), large electrolysis plants also have to compress correspondingly high volume flows, which has an effect on the sizes and, thus, on the investment costs, footprint, etc. of the machine equipment. In addition, hydrogen is very reactive, i.e. highly flammable. Special attention is, therefore, paid to the required explosion protection. The formation of an ignitable mixture with the atmospheric oxygen must be avoided at all costs.

The advantages of screw compressors for the compression of hydrogen

For the compression of hydrogen in the low-pressure range, screw compressors are a sensible solution or supplement to high-pressure compressors. Due to their design-related internal compression without free inertia forces, screws are above all reliable and flexible endurance runners with very low maintenance intensity and comparatively low operating costs in full and partial load operation. The AERZEN range includes both oil-free (VRA and VRW series) and oil flooded (VMY series) versions and achieves top marks in the fields of efficiency, installation space, economy and process reliability. All solutions are reconciled by the AERZEN process gas specialists to the customer's individual process.

VRW: maximum efficiency and increased differential pressure in one stage

The oil-free compressors of the VRW series (volume flows up to 6,000 m3/h, differential pressures from 3 to 9 bar) have been specially developed for the compression of saturated electrolysis hydrogen with unrivalled efficiency and differential pressure. Compression is based on the principle of oil-flooded screw compressors - with a small but subtle difference: the oil was replaced by water. The water serves both to cool the gas and to seal the gap, enabling compression to higher differential pressures with high efficiency. This stage can, thus, replace a two-stage system with classic oil-free screw compressors and is even more energy-efficient. For the customers, this results in significant advantages in terms of footprint as well as investment and operating costs.

VMY: highest differential pressures, maximum flexibility

The oil-injected screw compressors of the VMY series deliver the highest differential pressures and compression ratios in the AERZEN product portfolio (volume flows from 190 to 23,000 m3/h, differential pressures from 3 to 20 bar) and are characterised by maximum reliability and low operating costs. They are insensitive to fluctuating process parameters and gas compositions and are equipped with a control valve for infinitely variable control of the volume flow. The secondary rotor is not driven by timing gears (as with oil-free compressors), but by direct power transmission from the driven rotor.
