Compartment D is commonly empty because a series of JLLPs along the western portion of Fault A allows hydrocarbons to leak into Compartment B and then across the eastern portion of Fault A into the next highest reservoir. Only when Fault Ais cross sealing does Compartment D contain hydrocarbons. Cross seal is created by shale-prone gouge with low SGRs or sand/shale juxtaposition. | Compartment D is commonly empty because a series of JLLPs along the western portion of Fault A allows hydrocarbons to leak into Compartment B and then across the eastern portion of Fault A into the next highest reservoir.
