    摘要: The present invention provides an apparatus and methods to reduce ECD and pressure associated therewith while drilling with casing. In one aspect, the invention provides an energy transfer assembly locatable at a predetermined location in a casing string. The assembly includes an impeller portion in the interior of the casing to be acted upon by the downward moving fluid in the casing and a pump portion disposed outwardly of the impeller portion and arranged in fluid communication with the upward moving fluid in the annulus between the casing and the borehole, adding energy thereto and reducing pressure in the annulus therebelow. In another aspect, the energy transfer assembly is retrievable to the surface of the wellbore prior to cementing. In a further aspect, fluid ports between the interior and exterior of the casing are remotely sealable prior to cementing.

    摘要: A method and system of forming a lateral wellbore in a time and trip saving manner using a mill/drill to locate and place a casing window. In one aspect of the invention, a lateral wellbore is drilled with liner which is subsequently left in the lateral wellbore to line the sides thereof. In another aspect, the mill/drill is rotated with a rotary steerable system and in another aspect, the mill/drill is rotated with a downhole motor or a drill stem.

    摘要: The present invention generally relates to an apparatus and method for expanding a tubular body in a wellbore. In one aspect, a method includes running the tubular body into the wellbore, the tubular body having a deformed portion. The method further includes reforming the deformed portion and positioning a two-position expander in the reformed portion. Additionally, the method includes shifting the expander to a second, larger diameter position and then expanding the reformed portion by urging the expander therethrough. In another aspect, a method for completing a wellbore is provided. In yet another aspect, a formable launcher section is provided. In a further aspect, a two-position expander tool is provided. In yet another aspect, an expansion system for use in completing a wellbore is provided.
