Abstract
A method of casing multilateral wells and associated apparatus provide increased diameter in wellbores drilled below a casing splitter. In a described embodiment, a casing splitter is positioned in a subsea wellbore with a minimum restriction of 18.565″, with the casing splitter attached at a lower end of a 13⅜″ casing string. Two 8½″ bores extend through a lower end of the casing splitter, whereby only one standard casing size is skipped due to the wellbore junction formed by the casing splitter.
