ABSTRACT:
A well construction includes a spool (12) that is insertable into a vertical well casing (14). The spool (12) has a skirt (28) that seats against a collar (26) of the well casing (14). The skirt (28) and collar (26) are of a pre-selected angle and material so as to create a sliding and non-sticking engagement between the surfaces of the skirt (28) and the collar (26). A support web (50) extends substantially perpendicular to the surface of the skirt (28) at the location of the skirt (28). A pipe is suspended from a sleeve portion (44) of the spool and a ring portion (53) is formed at the junction of the support web (50) and the sleeve (44). The sliding and non-sticking engagement between the skirt (28) and the collar (28), coupled with the geometry of the spool (12), creates a load distribution in the support web (50) of substantially compressive forces between the surfaces of the skirt (28) and the collar (28), thus minimizing the incidence of breakage in the spool (12).
