    Abstract: An apparatus may include a tubular, a first isolator connected to the tubular and configured to engage an interior surface of the wellbore, a first pressure gauge connected to the tubular and configured to take multiple pressure readings over a period of time, and a first perforation gun connected to the tubular without compromising the communication of fluid through an inner flow channel of the tubular. A method may include placing the apparatus in a wellbore, and actuating the isolator to provide isolation of a first zone in a formation. The method may include activating the perforation gun to provide fluid communication between an annulus of the wellbore and the zone in the formation. The method may include allowing the pressure gauge to take a plurality of pressure readings over a period of time. Based on the pressure readings, the method may include determining a formation characteristic.

    Abstract: A method is provided to provide fractures in a subterranean formation that utilizes set of first wire line controllable valves (108) to open communication between the inside of a casing (107) and an outside of a casing that has been cemented into a wellbore (101). A wire line controllable valve associated with each of the first valves isolates the inside of the casing downstream of the first valve. The two valves are operated by a wire line actuator. After each successive fracture is formed, the wire line actuator is moved past the next set of valve, changing their positions, and then the next fracture is formed. The valve isolating the downstream portions of the casing are either opened, milled out, or made of degradable material after the operation is complete to enable production from the formation through the fractures into the well bore.

    Abstract: A method including providing sensors in injection and observation wells; increasing pressure within the injection well until a fracture extends from an initiation location through a portion of a subterranean formation to an intersection location in the observation well, wherein increasing pressure within the injection well comprises introducing fluid into the injection well; obtaining a measurement indicative of fracture initiation from the first sensor; determining a height of the fracture at the injection well; obtaining a measurement indicative of fracture intersection from the second sensor; determining a volume of fluid introduced between the fracture initiation and the fracture intersection; determining a distance between the initiation location and the intersection location; determining a time lapse between the fracture initiation and the fracture intersection; and using the determined values, calculating a hydraulic fracturing characteristic.

    Abstract: A method of stimulating a subterranean formation is provided. The method includes determining a final fracture spacing. The method includes creating a first set of fractures at a first fracture spacing, the first fracture spacing being larger than the final fracture spacing. The method includes allowing production of fluids from the formation through the well bore via the first set of fractures for a period of time. The method includes, after the period of time, creating a second set of fractures. The final fracture spacing is less than or equal to an average fracture spacing between the first set of fractures and the second set of fractures.

    Abstract: A borehole is drilled in an earth formation using consecutive steps of: (a) drilling a first open hole section of a borehole, employing a first drill string extending into the borehole from a surface on the earth, to a casing setting depth; (b) retrieving the first drill string from the borehole to the surface; (c) everting a tubular element in the open hole section, wherein axially advancing an inner tube section of the tubular element into the borehole through and in relative axial movement to an outer tube section of the same tubular element; (d) creating an annular seal between the outer tube section and an inward facing wall of the borehole; (e) inserting a second drill string through the inner tube section into the borehole; and (f) further deepening the borehole by drilling a second open hole section of the borehole.
