The disclosure provides a system and process for drilling a subterranean wellbore. An embodiment includes a bottom-hole assembly for a downhole mud motor that incorporates an information sub, such as a measurement-while-drilling or logging-while-drilling tool, at a location below, or down-hole from, the mud motor. The assembly also includes a micronized bit-to-bend length, or a length between a forward end of the assembly's bearing mandrel and a fixed bend in the assembly's housing, of less than or equal to forty inches. The combination of the forward-located information sub and micronized bit-to-bend length allow the driller to rely on real-time data relating to conditions adjacent to the drill bit/bottom of the wellbore and take that real-time drilling data into account in steering the bit along a planned wellbore trajectory. Other embodiments are also disclosed.

System and process for drilling a planned wellbore trajectory with a downhole mud motor

A downhole mud motor ( ) is disclosed which has an improved bearing mandrel ( ) and a bearing stop ( ) to transfer a larger percentage of the weight of a drill string to the bit. Also improved sealing systems ( ) ( ) ( ) ( ( ) for the transmission section and bearing section ( ) ( ) ( ) ( ) ( ) prevent drilling mud from entering critical components. A piston stop is provided to prevent the piston from damaging other parts as the piston moves under pressure. Compensating pressure assembly ( ) preferably including a disk ( ) is placed in the lower housing ( ) to prevent pressure from building up in the bearing section ( ). A combination of grooved ball seats ( ) and circumferentially spaced balls ( ) are provided in the transmission section ( ) ( ) to allow for greater flow of lubricant around the ball bearings.

Downhole mud motor

A bottom hole assembly for horizontal directional drilling that improves the accuracy of surveying while boring by enabling the progress of the bore to be monitored and tracked with the aid of a sonde. In one embodiment the sonde is received in the wall of a housing area of a mud motor surrounding the bearing mandrel, in another embodiment the sonde is carried in the wall of a collar surrounding the bearing mandrel housing, and in an additional embodiment the sonde is carried in an adapter between the bearing mandrel and the bit.

A downhole mud motor is disclosed which has an improved bearing mandrel and a bearing stop to transfer a larger percentage of the weight of the drill string to the bit. Also improve sealing systems for the transmission section and bearing section prevent drilling mud from entering critical components. A piston stop is provided to prevent the piston from damaging any parts as the piston moves under pressure. A compensating pressure disk is placed in the lower housing to prevent pressure from building up in the bearing section. A grooved ball seat is provided in the transmission to allow for greater flow of lubricant around the ball bearings.
