A hydraulic well packer having upper and lower slip assemblies with pivotable teeth therein for engaging the well casing to lock the packer in the casing and having elastomer seals between the upper and lower slip assemblies. A hydraulic assembly is coupled to the lower slip assembly for forcing it upwardly towards the upper slip assembly thereby compressing the elastomer seals outwardly against the well casing to form a liquid-tight seal and forcing the slip teeth outwardly to lock the well packer in place in the well casing.
