Abstract
A method of installing multiple strings within a wellbore. The method utilizes a carrier string having carrier string joints, a plurality of side strings each having side string joints, and a carrier tool for transferring the weight of the side strings to the carrier string permitting the side strings to be held, raised, and lowered within the wellbore by holding, raising, and lowering the carrier string. The carrier tool includes a body having a threaded through bore extending through the body and at least one threaded blind bore on the body. The method comprises the steps of engaging the carrier string joint into the carrier tool at the through bore so that the carrier string extends vertically upward and downward from the carrier tool, and engaging side string joints into the carrier tool at the at least one threaded blind bore.
