  • Patent number: 9234408
    Abstract: An example method may include determining a first planned stimulation location within the formation. The first planned stimulation location may be based, at least in part, on a pre-determined model of a formation. A borehole in the formation may be drilled with a downhole tool. The first planned stimulation location may be adjusted based, at least in part, on data received at the downhole tool. Additionally, the downhole tool may stimulate the formation at the adjusted first planned stimulation location. A second stimulation location also may be determined based on data received at the downhole tool after stimulation of the formation at the adjusted first planned stimulation location.

  • Publication number: 20150068735
    Abstract: Systems and methods for optimized well creation in a shale formation are described herein. The method may include determining a first planned stimulation location within the formation. The first planned stimulation location may be based, at least in part, on a pre-determined model of a formation. A borehole in the formation may be drilled with a downhole tool. The first planned stimulation location based, at least in part, on data received at the downhole tool. Additionally, the downhole tool may stimulate the formation at the adjusted first planned stimulation location. In certain other embodiments, a second stimulation location may be determined based on data received at the downhole tool after stimulation of the formation at the adjusted first planned stimulation location.

  • Patent number: 7240734
    Abstract: A system and method for controllably separating a conduit into an upper portion and a lower portion. The system includes a first valve in the upper portion of the conduit above a point of separation, and a second valve in the lower portion of the conduit below the point of separation. When the conduit is separated, the valves are actuated to cease flow therethrough and prevent loss of fluids into the seawater. A hang-off tool in the lower portion of the conduit engages the well and supports the lower portion of the conduit.

  • Patent number: 5813460
    Abstract: A downhole tool for early formation evaluation is disclosed. The tool comprising a housing having a fluid passageway and a mandrel having an interior volume. The mandrel is slidably disposed within the housing and has a plurality of axial positions relative to the housing. The mandrel is slidably operated responsive to the fluid pressure within the interior volume such that the mandrel cycles through said plurality of positions. A retractor sleeve is operably associated with the housing and the mandrel for engaging the mandrel and slidably urging the mandrel relative to the housing. The retractor sleeve is slidably operated responsive to the fluid pressure within the interior volume. A seal assembly is slidably disposed around the housing. The seal assembly includes a floating piston.
