Weekly News

Kalsi Seals-brand rotary seals have been used in rotary control devices (RCDs) for a number of years. Prior to this year, however, usage has been restricted to lubricant overpressure type RCDs, where the lubricant supply provides seal lubricant at a pressure that is several hundred psi greater than the pressure of the wellbore. A pair of Kalsi Seals are required in such systems: One to retain the pressurized seal lubricant, and the other to partition the wellbore fluid from the seal lubricant.

Consulting Engineering Services

Kalsi Engineering, Inc., a high technology firm, was founded in 1978 to provide consulting engineering services in the areas of research and development, design, analysis, and testing of mechanical equipment and structures. Our facilities are located in Sugar Land, Texas, approximately 17 miles from downtown Houston and easily accessible from the airports.

Kalsi Seals

Kalsi Seals® are a family of patented, one-piece rotary seals that provide hydrodynamic lubrication to minimize seal and shaft wear, and to accommodate high differential pressure.

Our Clients

Kalsi Engineering has a diversified client base that includes equipment manufacturers, oilfield service companies, petrochemical plants, nuclear power plants, aerospace engineering companies, architect/engineers, industry research organizations, and government agencies. In addition to serving individual clients, we have successfully completed many joint-industry group-sponsored projects.

Kalsi Bearings

The Kalsi Bearing is a patented, impact-resistant one-piece thrust bearing element that uses geometry-induced hydrodynamic lubrication to support heavy thrust loads on a lubricant film.

Our Products

In addition to providing consulting engineering services, Kalsi Engineering offers rotary seal, thrust bearing, and software product lines that were originally developed to solve difficult problems associated with energy production. Our patented rotary seals and thrust bearings are the result of our pioneering research in hydrodynamic lubrication.

Our suite of engineering software began with JarPro™ jarring analysis software, which is used to reduce the costs associated with a stuck drillstring by optimizing jarring tool placement. KVAP™, CVAP™ and LiFE™ are state-of-the art software applications that are widely used to evaluate critical valve and actuator issues in nuclear power plants.
