Xylem enhances water productivity in the oil and gas industry

Oilfield Technology,

From flood declining conventional and offshore wells to the water injected to fracture underground shale to the steam required for oil sands extraction, water is the most important input to the oil and gas industry.

The fact that its supply is under stress, renders water even more critical. By 2030, if current trends continue, global water demand is expected to exceed supply by forty percent. This trend is even more relevant in oil and gas production, as many of the world’s largest reserves reside in the most water-starved regions. Oil and gas producers should be concerned with water not only as a proactive step to be more efficient, but also as a defensive step against declining water supplies. Xylem is dedicated to helping solve water-related challenges around the world by protecting water quality, enhancing water productivity, and making water-intensive industries more resilient in the face of climate change and an uncertain regulatory environment.

The water-related challenges facing the oil and gas industry can be grouped into three issues: quality, productivity, and resilience. This article focuses on the issue of productivity.

Water productivity is about producing more economic output per unit of water and treating water resources as a source of competitive advantage rather than a cost to be diminished. Across the industry the productivity of water could be greatly improved using pipelines, onsite treatment, reusing produced and flowback water for fracking, temporary piping, and infill drilling to decrease the distance between wells. Xylem has helped energy producers become more productive by remote monitoring and controlling systems that allow the automated, real time management of water resources.

Xylem helped solve the water productivity challenge of the Chinese National Offshore Corporation

In the South Sea of China lies the Shenzhen liquefied natural gas platform. With high temperatures, humidity and strong winds, the setting is dangerous and not easily serviceable. Sea salt makes the water both abrasive and corrosive to equipment. The China National Offshore Oil Corporation (CNOOC) needed a firewater pumping system that was not only reliable but anticorrosive and low in maintenance as well. Additionally, the well depth of the pumps needed to be deeper than 30 m.

Xylem helped solve CNOOC's water productivity challenge by providing four high capacity

A-C Fire Pump skidded packages. A combination of ASTM B-148 C95800 and Monel stainless steel and ceramic components ensures superior resistance to the water’s abrasive features and is designed to last in this corrosive environment for more than 25 years. The pumps also feature a core-pulling design that enables easy maintenance onsite.

Xylem's expertise in innovative pumping technologies is helping CNOOC keep its offshore platform workers safe with fire pump systems that provide water supply in case of an emergency. The highly efficient, low-maintenance pumps will provide reliable performance in highly adverse conditions for decades to come.
