Abstract

Methods and systems of heating a body of crushed hydrocarbonaceous material to produce hydrocarbons therefrom can involve heating multiple zones of the body of material sequentially. An exemplary method can include forming a body of crushed hydrocarbonaceous material having a first zone and a second zone. The first zone can be heated in a first heating stage to form a dynamic high temperature production region in the first zone. A cooling fluid can then be injected into the first zone after the high temperature production region forms. The high temperature production region can move into the second zone in a second heating stage. Hydrocarbons can be collected from the body of crushed hydrocarbonaceous material during both the first and second heating stages.
