Tubular expansion fluid production assembly and method

A fluid production assembly for use downhole in a wellbore to seal with a casing string and transmit fluid between the casing string and a tubular patch within the casing string, the fluid production assembly comprising:

• a lower tubular anchor removably supportable on a running tool for positioning the lower tubular anchor downhole, the lower tubular anchor having an initial lower anchor inner diameter, and having an initial lower anchor outer diameter less than an inner diameter of the casing string, the lower tubular anchor being expandable by the running tool to seal with the casing string;
• a lower tubular expander removably supportable on the running tool, the lower tubular expander having a lower expander outermost diameter greater than the initial anchor inner diameter;
• an upper tubular anchor removably supportable on a running tool for positioning the upper tubular anchor downhole, the upper tubular anchor having an initial upper anchor inner diameter, and having an initial upper anchor outer diameter less than the inner diameter of the casing string, the upper tubular anchor being expandable by the running tool to seal with the casing string;
• an upper tubular expander removably supportable on the running tool, the upper tubular expander having an upper expander outermost diameter greater than the initial anchor inner diameter;
• the running tool including an actuator for forcibly moving each tubular expander axially from a position substantially axially spaced from the respective tubular anchor to a position substantially within the respective tubular anchor, thereby radially expanding the respective tubular anchor against the casing string to secure the respective tubular expander and the respective tubular anchor downhole;
• a sealing sleeve secured to an upper end of the lower tubular expander fluidly connecting the casing string, the lower tubular expander, and the sealing sleeve;
• a seal nipple for sealing with a bore of the sealing sleeve and fluidly connecting the sealing sleeve and the tubular patch;
• and
• an upper end of the tubular patch being sealed to the upper tubular anchor.

A method of sealing with a casing string to transmit fluid between the casing string and a tubular extending upward from the casing string, comprising:

• positioning an expandable tubular anchor and tubular expander on a running tool, the tubular anchor having an initial anchor inner diameter, and an initial anchor outer diameter less than an inner diameter of the casing string, the tubular expander having an expander outermost diameter greater than the initial anchor inner diameter, and a sealing sleeve secured to an upper end of the tubular expander;
• positioning the running tool at a selected depth within a wellbore;
• actuating the running tool to forcibly move the tubular expander axially to a position substantially within the tubular anchor to radially expand the tubular anchor against the casing string, thereby securing the tubular anchor and the tubular expander downhole;
• and
• fluidly connecting a seal nipple to the sealing sleeve.
