Casing shoe assembly

A method of drilling a wellbore, comprising:

• lowering a casing string comprising a casing shoe assembly into a primary wellbore, wherein the casing shoe assembly comprises:
• an outer housing;
• an inner body at least partially disposed within the outer housing and formed out of a drillable material, the inner body comprising a bore formed through the inner body;
• a check valve assembly disposed within the bore of the inner body and configured to allow fluid flow in one direction and prevent fluid flow in the opposite direction;
• a guide plate disposed within the outer housing above the inner body having a plurality of wellbore openings formed through the guide plate and a separate opening formed through the guide plate to provide fluid flow into the bore formed through the inner body;
• and
• a wellbore guide located below each wellbore opening of the guide plate and within a hole formed in the inner body, wherein each wellbore guide and each hole does not extend through the entire inner body;
• cementing the casing string in the primary wellbore by flowing cement through the casing string, through the bore of the inner body, and out of the casing shoe assembly into the primary wellbore;
• lowering a drill string through the casing string;
• directing the drill string into one of the plurality of wellbore openings of the guide plate and through the wellbore guide located below the wellbore opening;
• drilling through the inner body and out of the casing shoe assembly to drill a first wellbore below the primary wellbore;
• lowering the same or a different drill string through the casing string;
• directing the same or the different drill string into one of the other plurality of wellbore openings of the guide plate and through the wellbore guide located below the wellbore opening;
• and
• drilling through the inner body and out of the casing shoe assembly to drill a second wellbore below the primary wellbore.
