A casing junction member connects in a well between a main casing and a lateral branch casing. The junction member has an upper end portion which connects to the main casing extending above the member. It has a lower end portion that is coaxial and connects into the main casing below the junction member. The junction member has a lateral section which joins the main section at a junction and extends downward for connecting to lateral branch casing. The junction between the main section and the lateral section has a lower perimeter portion that is generally in the shape of a parabola. A stiffening member is joined to the lower perimeter portion of this junction. The stiffening member is located in a plane containing the lower perimeter portion of the junction.
