    摘要: Processes and systems for drilling a borehole wherein a gravitational energy term, a torsional energy term, a hydraulic energy term and a hydromechanical specific energy which is the sum thereof may be determined using real-time data and compared against corresponding setpoints. The hydraulic energy term may include a hydraulic energy reduction factor so as to account for the distance between the fluid nozzle of the drill bit and the rock and may include the kinematic viscosity of drilling fluid. One or more drilling parameters, such as weight on bit, revolutions per minute, drilling fluid flow rate, or combinations thereof, may be adjusted based upon such comparison to approximate the least amount of energy required to destroy and remove a given unit volume of rock. The setpoints may be changed manually or automatically at the direction of the user.

    摘要: Processes and systems for logging production of fluid produced into a well bore without intervention of the well are disclosed. Two or more markers may be introduced into produced fluid at spaced apart locations along a well. The time for each marker to reach a common point may be measured and production rates for produced fluids at each spaced apart location may be calculated.

    摘要: An apparatus for stimulating a subterranean formation includes a first tube, a second tube, a combustion body and an ignition propagator. The second tube is positioned within the first tube interior and the second tube interior is sealed from the first tube interior to substantially prevent fluid communication between the first tube interior and the second tube interior. The combustion body is formed from a solid propellant and is positioned within the first tube interior external to the second tube interior. The ignition propagator is positioned within the second tube interior and is substantially free from fluid contact with fluid residing in the surrounding environment external to the first tube wall.

    摘要: A method for stimulating a subterranean formation (14) which is penetrated by a well bore (10) having casing (11) positioned therein so as to establish fluid communication between the formation and the well bore. Propellant (50) is secured to the outer surface (48) of a carrier (44) having a plurality of apertures (45) formed therein. Detonating cord is positioned within said carrier and when ignited causes the propellant to ignite initially at each aperture. In this manner, the propellant is caused to burn in controlled, uniform manner. Upon burning, the propellant generates gases which clean perforations previously formed through the casing into the formation and which extend fluid communication between the formation and the well bore.

    摘要: A method and apparatus for perforating and stimulating a subterranean formation (16) which is penetrated by a well bore (10) having casing positioned therein so as to establish fluid communication between the formation and the well bore. Substantially rigid, flexible, or liquid propellant (20) is interposed between the casing (12) and at least one shaped charge (40) in a subterranean well bore and is ignited due to the shock, heat and/or pressure generated from the detonated charge. Upon burning, the propellant material generates gases which clean perforations formed in the formation by detonation of the shaped charge(s) and which extend fluid communication between the formation and the well bore.
