an apparatus and method are disclosed for improving the formation of multiple lateral wells in a new wellbore and positive , selective reentry of each lateral well . the apparatus functions as an orienting sleeve which is attached to the lower end of the casing used to line the wellbore . the orienting sleeve includes a first end connected to one end of the casing , a second end having a plunger valve , a longitudinal reference point and a lateral reference point . the orienting sleeve cooperates with a sealing member and an orienting member . the sealing member is used to transfer cement from a surface above the wellbore to an area between the casing and the wellbore . the orienting member is used to effectively form multiple lateral wells through the casing or pre - formed openings in the casing . thus , the orienting sleeve effectively secures the casing to the wellbore and improves the formation of multiple lateral wells using one or more pre - formed openings in the casing .
