摘要： An apparatus for installing two sensing instruments and cables inside of a single tubing string in a wellbore for monitoring well conditions at two different locations includes an upper sensor attached to an inner sleeve seated at a first location in a ported outer sleeve in the tubing string. The upper sensor is allowed to be in pressure communication with the exterior of the tubing string at the first location. A second lower sensor is deployed on a pump down cup (PDC) assembly to a lower depth in the outer sleeve to allow fluid pressures to be monitored at a second location in the wellbore.

摘要： A subterranean tool can drop multiple objects to landing locations in a tubular string. The tool can keep at least one ball out of the fluid stream until ready for release. A dart or wiper plug can be kept in the fluid stream with an open bypass until axial mandrel movement allows release of the plug or dart. The tool is rotationally locked at a lower location for run in and then can rotationally lock at an upper location upon release of the dart or ball. Axial movement that releases the dart can continue until the ball aligns with a decreasing depth groove so that relative part rotation cams the ball against a leaf spring detent and into the mandrel flow path.

摘要： A fracturing operation is done in open hole without annular space isolation. The annular space is spanned by telescoping members that are located behind isolation valves. A given bank of telescoping members can be uncovered and the telescoping members extended to span the annular space and engage the formation in a sealing manner. Pressurized fracturing fluid can be pumped through the telescoped passages and the portion of the desired formation fractured. In a proper formation, cementing is not needed to maintain wellbore integrity. The telescoping members can optionally have screens. Normally, the nature of the formation is such that gravel packing is also not required. A production string can be inserted into the string with the telescoping devices and the formation portions of interest can be produced through the selectively exposed telescoping members.

摘要： A method for drilling and completing multiple wellbores in a subsurface rock formation includes drilling a first wellbore along a first selected trajectory through the rock formation. The first wellbore is fracture treated and then abandoned. A second wellbore is drilled along a second selected trajectory through the rock formation. The second trajectory is laterally spaced from the first trajectory. The second wellbore is then fracture treated and abandoned. A third wellbore is drilled along a third selected trajectory through the rock formation. The third trajectory is disposed between the first and second trajectories. The third wellbore is fractured treated such that a fracture network extending therefrom hydraulically connects to fracture networks extending from the first and second wellbores.
