Wellbore liner apparatus has been invented which, in one aspect, includes at least one tubular member for lining at least part of a lateral wellbore extending from a primary wellbore in the earth, at least one coupling bushing connected to the at least one tubular member and disposed in the primary wellbore, the coupling bushing having a bore therethrough from a top to a bottom thereof. In one aspect, the wellbore liner apparatus has two coupling bushings and a first tubular member and a second tubular member, the first tubular member secured to and extending down from the first coupling bushing to the second coupling bushing which is secured thereto, the second tubular member secured to and extending down from the second coupling bushing, with part of the second tubular member lining the lateral wellbore. Such systems are combinable with a wellbore milling system so that communication between the primary wellbore and the interior of the liner may be reestablished.
