Abstract: In one embodiment, a method for drilling a wellbore includes an act of drilling the wellbore by injecting drilling fluid through a tubular string disposed in the wellbore, the tubular string comprising a drill bit disposed on a bottom thereof. The drilling fluid exits the drill bit and carries cuttings from the drill bit. The drilling fluid and cuttings (returns) flow to a surface of the wellbore via an annulus defined by an outer surface of the tubular string and an inner surface of the wellbore. The method further includes an act performed while drilling the wellbore of measuring a first annulus pressure (FAP) using a pressure sensor attached to a casing string hung from a wellhead of the wellbore. The method further includes an act performed while drilling the wellbore of controlling a second annulus pressure (SAP) exerted on a formation exposed to the annulus.

Abstract: A system and method are provided for direct connecting downhole control hydraulics through an oil field hanger, where the hanger is coupled to a wellhead, to hydraulic lines extending outside the wellhead. Further, the direct connection allows hydraulic system integrity with reduced contamination and leakage. Hydraulic tool ports, formed on the hanger, are coupled with hydraulic lines extending downward to a hydraulic tool. Side ports, formed in the hanger, are fluidicly coupled to the hydraulic tool ports. Hydraulic lines extending outside the wellhead are directly coupled with the side ports by accessing the side ports through access openings in the wellhead when the ports are aligned with the access openings. The system can still maintain pressure within internal spaces of the wellhead after the connection by sealing the access openings with flanges, where the hydraulic lines extend through openings in the flanges that are also sealed around the lines.

Abstract: A tool used for treating and/or maintaining a wellbore that includes acoustic transducers for locating a lateral wellbore that intersects a primary wellbore. The tool includes a sensor to sense water and/or gas, and if the water and/or gas enters the primary wellbore from a lateral wellbore, the lateral to primary intersection can be identified by correlating information from the sensor and acoustic transducers. If needed, the tool can be used to plug the water and/or gas supplying lateral wellbore. The tool may include a bendable sub portion for orienting a portion of the tool for insertion into the lateral wellbore and a plug section for plugging the lateral wellbore after insertion therein.

Abstract: A system for damping vibration in a drill string can include a magnetorheological fluid valve assembly having a supply of a magnetorheological fluid, a first member, and a second member capable of moving in relation to first member in response to vibration of the drill bit. The first and second members define a first and a second chamber for holding the fluid. Fluid can flow between the first and second chambers in response to the movement of the second member in relation to the first member. The valve assembly can also include a coil for inducing a magnetic field that alters the resistance of the magnetorheological fluid to flow between the first and second chambers, thereby increasing the damping provided by the valve.

Abstract: A drill bit direction system and method is disclosed that modifies or biases the stochastic movement of the drill bit and/or stochastic interactions between the drill bit and an inner-wall of a borehole being drilled by a drilling system to change the direction of drilling of the drilling system. The direction of the drill bit is monitored to determine if the direction happens to align in some way with a preferred direction. If the direction isn't close enough to a preferred direction, a biasing mechanism modifies the stochastic movement in an attempt to modify the direction closer to the preferred direction. Any of a number of biasing mechanisms can be used. Some embodiments can resort to conventional steering mechanisms to supplement the biasing mechanism.

Abstract: Methods and apparatus to form a well are disclosed. An example method involves determining a reservoir fluid map associated with at least a portion of a reservoir. The first fluid map has first fluid composition data associated therewith. The example method also involves measuring a formation fluid and determining a second fluid composition data based on the measurement. The second fluid composition data is compared with the first fluid composition data associated with the reservoir fluid map, and a well trajectory is adjusted based on the comparison.
