[[:file:applying-gravity-in-petroleum-exploration_fig15-14.png|Figure 3]] shows a synthetic model of the configuration of a theoretical drawdown gas cone around a producing well, modeled after the Prudhoe Bay field, Alaska. Since so little is known about the shape of gas coning, present logging methods can severely underestimate the true [http://www.glossary.oilfield.slb.com/en/Terms.aspx?LookIn=term%20name&filter=gas-oil%20contact gas-oil contact] in the reservoir away from wells. [[Borehole gravity]] can determine the shape of the gas cone as well as locate the true gas-oil contact at a distance from the producing wells. Logs A, B, and C correspond to different gas cones shown in the model. | [[:file:applying-gravity-in-petroleum-exploration_fig15-14.png|Figure 3]] shows a synthetic model of the configuration of a theoretical drawdown gas cone around a producing well, modeled after the Prudhoe Bay field, Alaska.
