Nonlinear (exponential) regularities of the variation in the density of the rocks from coeval sedimentary complexes are presented. A series of direct and inverse tasks with and without consideration of the vertical density gradient were solved for the detailed and high-accuracy gravity exploration typical of petroleum geology. It was concluded that an increase in accuracy of a gravity survey better than ±0. 20 mGal is of doubtful value if there is no possibility to create and account for the petrodensity dependences σ(Z). The lateral variability of the lithophysical properties of petroleum complexes of local objects is characterized. Algorithms of mathematic programming and the method of 3D geodensity modeling of the objects searched for using seismic exploration are suggested. The inverse linear tasks of high-accuracy gravity exploration are solved by a near-real model universal in complexity, which allowed us to reveal and contour noncompact (highly porous) lithofacies. Within the accepted model, the 3D task of the high-accuracy gravity exploration was solved for the Verkhnenysh gas condensate deposit in Sakhalin.
