NOV于2016年中期收购了Trican Well Service有限公司的完井工具业务，虽然该公司的规模和市场辐射范围有限，但它给NOV带来了高质量的滑套产品线、丰富的知识产权组合以及可靠的团队。在过去一年中，该团队又有计划地开发了几种补充产品，并通过收购一些一流的尾管悬挂系统和智能完井工具技术，然后对这些产品进行了完善。如今，NOV的完井工具业务遍及10个国家，拥有大约100项已批或待批专利。
（1）Bulldog Frac™ 压裂系统——滑套环空压裂系统，可进行分段压裂，压裂精度高，可靠性也更高;
（5）German Oil Tools——世界一流的尾管悬挂系统和其他完井工具技术、产品和配件的生产线。

German Oil Tools尾管悬挂器技术
German Oil Tools公司（2017年6月被NOV收购）拥有一套经多方验证，以质量和可靠性而闻名的建井和完井产品组合。目前在欧洲、中东和非洲都有销售。NOV将继续在德国对包括GPS Oil Tools在内的业务进行开发制造，以保持高标准的质量、工艺和创新。同时GOT也会受益于NOV的全球销售结构和供应链，提高产能水平，以满足全球对可靠经济的完井解决方案不断增长的需求。
NOV Expands Completion Tool Technology Product Offering
NOV acquired a small completion tool company in mid-2016 that had limited scale and geographical reach but offered a high-quality sliding sleeve product line, strong portfolio of intellectual property, and solid team. Over the past year, this team organically developed several complementary products and supplemented that development with acquisitions of what we believe are best-in-class liner hanger and intelligent completion tool technologies. Today NOV completion tool business operates in 10 countries, has approximately 100 patents issued or pending, and we continue to expand our operations.
National Oilwell Varco, Inc. (NYSE: NOV) announced today the introduction of several new proprietary technologies to its completion tools portfolio:
（1）Bulldog Frac™ – a sliding-sleeve annular fracturing system that provides pinpoint accuracy, zonal isolation, and improved reliability;
（2）Bullmastiff™ – a ball-drop openhole sliding-sleeve sand control fracturing system;
（3）Rottweiler™ – a product family of compact, high-performance frac plugs for the plug-and-perf market;
（4）ReAct™ – an intelligent completion tool technology that offers remote signaling capabilities for valves and sleeves for a variety of applications and completion designs; and
（5）German Oil Tools – a line of advanced liner hanger systems and other completion tool technologies, products, and accessories.
“We are proud to unveil this meaningful expansion to our portfolio of leading-edge completion tool technologies,” commented Clay Williams, NOV Chairman, President, and CEO. “NOV now offers a comprehensive set of differentiated completion tool products and solutions that we believe address the most pressing needs within the global marketplace.”
Bulldog Frac Pinpoint Annular Fracturing System
The Bulldog Frac annular fracturing system enables operators to precisely control the placement of proppant in each stage by pumping down the coiled tubing annulus through Multiple Open/Close (MOC) sliding sleeves, providing for an unlimited number of stages and leaving no restrictions in the wellbore. The Bulldog Frac system addresses the operational challenges of most MOC systems with a “shift up to open” design, performed with NOV’s proprietary hydraulic shifting tool, which ensures no sleeves are accidentally closed on the trip out. Unlike competitors’ products, Bulldog frac sleeves are compact, lightweight, and do not require handling pup joints, allowing for safer and more efficient installation. Additionally, the Bulldog incorporates NOV’s patented and field-proven sealing system, which offers full pressure testing of previously manipulated sleeves even after several years in service.
Bullmastiff Openhole Sand Control Ball-Drop Fracturing System
The Bullmastiff fracturing system is a proprietary openhole sliding-sleeve system that incorporates sand screens to eliminate costly sand-production issues while maximizing hydrocarbon production. The ball-drop frac sleeve component is the first to allow for proppant stimulation with integral sand control, segregating the stimulation port from the production port. The Bullmastiff incorporates NOV’s patented flex sleeve and sealing technology to allow for maximum stage-count flexibility.
Rottweiler Frac Plugs
Compact, large-bore Rottweiler frac plugs are the shortest on the market but still offer optimum performance during fracturing operations. Rottweiler frac plugs can be pumped in at high displacement rates, hold high differential pressure, and are easily milled. Additionally, Rottweiler frac plugs are the only products to offer a built-in chemical tracer that provides real-time data on reservoir characteristics during frac jobs to enhance production. Rottweiler frac plugs are currently available in cast-iron, with a composite version expected to be released in the near future.
ReAct Remote Activation Technology
The ReAct product family, which was acquired from Omega Completion Technology, offers remote signaling capabilities to downhole valves and sleeves. The technology can be utilized for a number of applications including programmable sleeves, which respond to a particular pressure or flow signal and require no hydraulic or umbilical lines to surface. The ReAct technology currently has applications for inflow control (for water shutoff or zonal isolation), liner hanger deployment, production packer setting, and wellbore cleanup in preparation for flow-through sand screen completions. These interventionless solutions provide the lowest-cost intelligent completion technologies on the market.
German Oil Tools Liner Hanger Technologies
German Oil Tools offers a proven portfolio of well-construction and completion products that are highly regarded for quality and reliability and are currently sold in Europe, the Middle East, and Africa. The operation, which includes GPS Oil Tools, will continue to develop and manufacture products in Germany to retain high standards of quality, craftsmanship, and innovation, but will benefit from NOV’s global sales organization and supply chain to accelerate its ability to meet customers’ growing demand for reliable, cost-efficient completions solutions around the world.
