The annual American Houston oil exhibition OTC was organized by the American Petroleum Engineering and Technology Association (SPE) in 1969, and was strongly supported by 12 professional organizations such as the American Petroleum Association. Through the development of new technology in oil and gas industry for more than 40 years, it has now become the exploration and exploitation of oil and natural gas in the world. The most important professional exhibition in the field of production and environmental protection. The exhibition is the best platform for all the exhibitors and industry people to enter the United States, Canada and the European market, with the world’s major oil companies and many excellent international oil machinery suppliers and buyers from all over the world.

As China’s domestic market is saturated and the situation of oil supply is becoming more and more severe, Chinese energy enterprises need to "go out" to promote their own advantages and make full use of overseas oil and gas resources. Therefore, more and more Chinese energy enterprises have brightened the prestigious OTC stand. On -4 May 1, 2017, Wang Zhang, the founder of our company, went to Houston in the United States to participate in the world’s largest oil industry exhibition: the forty-eighth U. S. OTC international oil and natural gas exhibition. It also conducted technical exchanges and business talks with international drilling contractors and oil equipment manufacturers all over the world, including American NABORS industry, American PRIDE International Corporation, Canadian precision drilling company, British KCADEUTAG drilling company, American HELMERICH&PAYNE company and American PARKER drilling company.
