TITLE: Adjustable Bent Housing INVENTOR: Walenty Michalik ABSTRACT An adjustable bent sub for use in directional drilling has a bent mandrel having a splined section, a bent housing having a thrust end and a distinct splined end and being rotatable in relation to the bent mandrel, the splined section of the mandrel being engagable and disengagable with the splined end of the housing, a first shoulder on the mandrel, a second shoulder on the thrust end of the housing, and the first and second shoulders abutting each other for transmitting thrust forces. The bent sub then includes two rotatable parts (the mandrel and the housing), in which thrust forces are transmitted downhole without passing through the splines which hold the rotatable parts fixed in relation to each other. The housing is separable in two parts for allowing the engaging and disengaging of the splined section of the mandrel and the splined end of the housing.
