Top drives reduce risk and increase safety while drilling in several ways. First, a top drive allows the driller to more quickly engage and disengage pumps or the rotary while removing or restringing the pipe. Typically, the frequency of pipe getting stuck is significantly reduced when using top drives, thereby resulting in cost savings. Additionally, top drives reduce much of the manual labor that, until recently, was largely associated with drilling wells.

Tesco’s founder Bob Tessari engineered the world’s first portable top drive system for land rigs. Ever since, Tesco has continued to develop and grow this product offering to become known as The Drilling Innovation Company™. Now, more than ever, Tesco maintains the principles of quality and innovation upon which it was founded. These essential values are evident through Tesco’s continual improvement and increasing variety of top drives that Tesco offers. Tesco has the widest range of top drives available on the market including electric, hydraulic and even custom-integrated models.

Whether building the next generation of AC class rigs, retrofitting a mature mechanical rig or replacing an older model, Tesco can provide a top drive for any application. Staying close to the company’s history, Tesco’s Rig Integration Specialists & Engineering (RISE) team is ready to assist in the development and integration of Tesco’s equipment into rigs of the future or an older class of rigs ready to see a new age of drilling.
