Downhole Motors

Since its introduction in 1956, the positive-displacement motor has undergone revolutionary changes and improvements.

Downhole drilling motors have proven to be successful in the most rigorous drilling environments. Nowadays, horizontal drilling, steerable systems, extended reach drilling, and conventional direction drilling have all become routine. The technological advances in these various types of drilling operations have reduced drilling and production costs and have significantly improved the odd of bring in a successful well.

Bico Thru Tubing Drilling Motors

Bico SpiroStar motors can be used in various thru tubing applications, including production, remedial operations, and new drills.

Thru tubing motors can also be deployed for drilling through cement plugs, frac plugs, sand bridges, paraffin cleanouts and window milling. Bico’s unique SpiroStar power sections provide improved performance in environments known to degrade conventional motor performance, including high temperature and areas with high concentrations of certain harsh chemicals which may include aromatic compounds.
