The author points out that the combination of horizontal observable should be used in the form of the complex number in the study of gravity field through an inspection of the principles of torsion balance and rotational gradiometer and the discussion of the acquisition of height anomaly from vertical deflections according to Molodensky's, as well as the fact that some combination of horizontal gradient components are orthogonal functions on a spherical surface.

The combined production of vertical and horizontal wells can make horizontal well production rates be 2 to 5 times greater than unstimulated vertical well rates, but the areal sweep efficiency is less than that of vertical well pattern untill when the perforation ratio is greater then a certain value, which depends on the pattern of the combination. Seven spot pattern of the combination of vertical and horizontal wells has some advantages over others.

Based on the horizontal and vertical combination in formal contexts, this paper defines the independent or consistent contexts and lattices in attribute field; and also defines the horizontal addition operation between contexts or concepts and the horizontal union operation between concept lattices. In addition, we prove that the concept lattice of subcontexts horizontally combined is isomorphic to the horizontal union of sublattices of these subcontexts.
