Oilfield - Downhole Slip Rings
Exploration and production of oil and gas is becoming more difficult. The easy reserves have already been found and new ones are deeper or in more difficult formations. Drilling can now extend to depths of 10 km and can be multi-directional or horizontal. Temperatures and pressures can be up to 260°C and 2000 bar (29,000 psi). As a result, the cost to recover these reserves is very high – making efficiency even more important.
Since 1998, Moog has worked with the major oilfield service companies and equipment manufacturers to solve demanding and unique problems for the difficult downhole environment.
The need to maximize output from new reserves (as well as existing reserves) requires the need for higher performance equipment and better information from the well. To answer the demand, Moog has developed a line of oilfield and downhole equipment and technology that meets the challenge.
