The 2020 Offshore Technology Conference (OTC) has been canceled due to the COVID-19 pandemic. Kalsi Engineering invites you to join us at OTC 2021.

Rotary Seals – Stop by our booth to meet the engineers who are at the forefront of polymeric high-pressure rotary sealing technology. Learn directly from them about our latest advances in high-pressure rotary shaft seals, and how to implement them in your assembly.

While you’re there, take the time to examine our Extra Wide Seals for Rotary Control Devices (RCDs), so you can understand why this robust elastomeric seal is so capable as a high-pressure RCD seal. Have a look at the data from the fixture we developed to test full-size RCD seals in high pressure conditions, and then learn about our Plastic Lined Seals™, which have even more pressure capacity than the Extra Wide elastomeric seals. Also have a look a pair of used 10.50” seals that endured 200 hours of operation at 100 rpm and 2,300 psi, while mounted in conventional non-floating seal carriers. Learn about our KLS® and BDRP Seals™, which were developed for lower cost rotary heads that do not incorporate lubricant overpressure systems.

Also learn about our continuing advances in hardware implementations that enhance rotary seal performance in high pressure conditions by dramatically reducing extrusion gap clearance. Improvements include composite construction that reduces pressure and temperature-related dimensional changes, geometry innovations that provide improved torsional stability and accommodate smaller extrusion gaps, and enhancements to the force-balancing seals, including higher pressure capacity and reduced friction. Learn how these advances can improve seal performance in various types of equipment, such as RCDs, high pressure swivels, cementing heads, and washpipe assemblies.

Jarring Software – JarPro™ is a general-purpose jarring analysis program used by leading jar manufacturers, oil companies, and equipment/service companies. It helps to reduce the cost of freeing stuck drillstring by facilitating selection and placement of jars and accelerators, and provides detailed time histories of jarring impact. The software is also capable of analyzing the effects of multiple jars.  It has an intuitive user interface, and can be customized to fit the needs of your organization, such as including your equipment in pulldown menus.

Consulting Engineering – In addition to our jarring software and rotary seal product line, Kalsi Engineering offers a wide variety of consulting engineering services, including the design of testing apparatus for the oilfield industry.  Our staff has an outstanding background, and an accomplished record of practical mechanical engineering solutions for a variety of mechanical equipment used in the oilfield and petrochemical industries. Examples of equipment we have worked with include downhole tools, wellhead and drilling equipment, pressure vessels and piping components, reactor vessels, heat exchangers, valves, actuators, and pumps.  We have two laboratories dedicated to mechanical, structural, and environmental testing.  We also offer an indoor flow loop testing facility.

We have special expertise in the area of validated, state-of-the-art FEA and CFD solutions to some of the most complex problems involving fluid/structure/thermal interactions. Our two super computers can efficiently handle very large scale non-linear problems exceeding 100 million degrees of freedom.
