  • Steering tool with eccentric sleeve and method of use
    Patent number: 10000971
    Abstract: A method for steering a well comprises disposing a first orienting assembly and a second orienting assembly spaced apart along a circular inner peripheral surface of a housing. An orienting sleeve is rotatably supported between the first orienting assembly and the second orienting assembly, The orienting sleeve has an angled bore therethrough, wherein a first longitudinal axis of the angled bore is inclined by a predetermined angle to a second longitudinal axis referenced to a cylindrical outer peripheral surface of the orienting sleeve. A rotatable steering shaft is rotatably supported along the angled bore to control rotatable steering shaft bending. The rotation of the first orienting assembly, the second orienting assembly, and the orienting sleeve is controllably adjusted to control the steering direction of the rotatable steering shaft.
