ABSTRACT:
Conventional surface gravity measurements, either land, sea, or sea bottom, are made along a line that lies approximately along the same surface orientation as the deviated well. Borehole gravity measurements are made in the deviated part of the well along the wellbore at stations lying approximately below those taken on the surface. The gravity difference is computed from the station pairs. From the gravity difference and the vertical distance between the two readings, the average density is computed for all the station pairs. From a depth model interval depths at each layer between the surface and the borehole stations are computed. The average density between any station pairs can be related to the interval densities and the layer densities are calculated.
