our proprietary technologies enable Flowserve to synthesise essential data for our customers’ most critical pieces of equipment and proactively manage the conditions that can impact plant performance.” In a separate development, Flowserve has entered into a definitive agreement to acquire Lawrence Pumps, a privately-owned US manufacturer of highly engineered critical service centrifugal pumps used primarily in the petrochemical and oil and gas industries.

Te acquisition of Lawrence will provide

Flowserve with severe service API and chemical slurry pump technology that is critical to the refining, oil sands, polyolefin and polyethylene industries- all of which are core markets for Flowserve. “Lawrence has consistently been an industry leader in critical slurry services solving complex pumping problems involving solids and high temperatures in our core markets,” said Tom Ferguson, president, Flowserve Flow Solutions Group. “Te Lawrence brand has an outstanding reputation, and many Lawrence products have proprietary niche applications that strategically complement our industry-leading portfolio. We look forward to leveraging our expansive network of service centres and global sales force to expand the reach of Lawrence products and capture unrealised aftermarket potential as we continue to serve the needs of our customers.”

Progressive cavity pumping Te Anschutz Ranch in Evanston, Wyoming, is an old gas field that has been operating for almost 20 years. Te natural gas is trapped in the porous rock like water in a sponge. As the gas is removed

it also draws out a large amount of ground water. When the field was first developed it had a natural pressure of over 700psi. Te natural gas, water and other hydrocarbons were moved through the field pipelines by the natural pressure of the field. Slowly the natural pressure in the field dropped. Eventually, it became necessary to use

compressed air to push the natural gas and hydrocarbons out of the rock formation. Te air would then push the natural gas, hydrocarbons and water through the porous rock to an extraction point. At first, the added production more than paid for the additional cost of large compressors and to separate the air, water and natural gas. But the economics of the field changed. As the natural gas in the field became further depleted a significantly greater amount of compressed air was needed and the process was no longer feasible. So BP had a challenge to improve production and keep the field profitable. At this point it became evident that the compressed air was travelling through the more porous areas of the rock formation where the natural gas had already been removed. Also, where the formation was less porous and contained large amounts of very high quality gas, the compressed air was not effective. If the injection into the formation was to be discontinued, then the higher quality gas would come out naturally, however, the volume would be lower. It was determined that the benefits of this high quality natural gas would offset the cost of operating the compressors. Dropping the field pressure would mean that the gas, hydrocarbons and water mixture would need to be pumped across the field. Tis would require a novel pump solution. After investigating many different types of pumps,

US$40m Weir SPM expansion W

eir Oil & Gas has announced an extensive capacity expansion of

its Weir SPM business manufacturing and service facility in Fort Worth, Texas. Te US$40 million investment is part of the company’s aggressive growth strategy that aligns with its increased business in drilling and hydraulic fracturing caused by a rise in horizontal rig counts supported by oil and liquid rich shale in North America.

Te expansion includes purchase of 12.7 acres adjacent to the current location for creation of a dedicated


Fort Worth Service Centre to provide quick response times for major pump overhaul. Construction will also include multiple warehouses, an assembly and engineering office, pipe shop, pump machine shop, a swivel manufacturing facility and service centre. Construction is under way and the

impact of the investments is already starting to take effect. Renovations and construction are expected to be completed by the third quarter of 2012. Steve Noon, divisional md of Weir Oil & Gas, said: “We will continue

to invest in Weir SPM. Since its acquisition in 2007, Weir SPM has maintained a market-leading position in this niche segment of the oil and gas industry. Te expansion in Fort Worth will support our extensive service footprint and will provide additional capacity to meet our customers’ needs.” Weir SPM has also launched a new triplex frac pump, the Destiny TWS2500, to address industry demand for high performance in the harsh environments of North American shale plays. ●
