1 CPH Oil Curtis P. Henderson

2 CPH What is Petroleum? Petroleum:a natural yellow-to-black flammable liquid hydrocarbon found beneath the earths surface Petroleum:a natural yellow-to-black flammable liquid hydrocarbon found beneath the earths surface Hydrocarbon:an organic compound made up of carbon and hydrogen atoms Hydrocarbon:an organic compound made up of carbon and hydrogen atoms

3 CPH Petroleum Products Gasoline gallons A Barrel of Crude Oil Provides: Fuel Oil gallons Jet Fuel gallons Asphalt gallons Kerosene gallons Lubricants gallons Petrochemicals, other products gallons One Barrel = 42 gallons American Petroleum Institute, 1999

4 CPH Petroleum System Processes Accumulation Source Rock

5 CPH Casing Drill Pipe Bit Drilling Rig

6 CPH Drilling Rock Bit Cuttings Core (Diamond) Bit Core

7 CPH Petroleum System Elements (Impermeable) (Porous/Permeable) Potential Migration Route

8 CPH Hydrocarbon Trap Types American Petroleum Institute, 1986 Salt Dome Fault Unconformity Pinchout Anticline

9 CPH Traps Anticlinal - Rock layers folded into a dome Anticlinal - Rock layers folded into a dome Stratigraphic - Rock layers changing from a good reservoir to non-reservoir due to change in rock type (pinch-out), reservoir quality (diagenesis), or removal (erosional unconformity) Stratigraphic - Rock layers changing from a good reservoir to non-reservoir due to change in rock type (pinch-out), reservoir quality (diagenesis), or removal (erosional unconformity) Fault - Offset of rocks such that oil and gas accumulates in reservoir rock Fault - Offset of rocks such that oil and gas accumulates in reservoir rock

10 CPH Petroleum System Elements Source Rock - A rock with abundant hydrocarbon-prone organic matter Source Rock - A rock with abundant hydrocarbon-prone organic matter Reservoir Rock - A rock in which oil and gas accumulates: - Porosity - space between rock grains in which oil accumulates - Permeability - passage-ways between pores through which oil and gas moves Reservoir Rock - A rock in which oil and gas accumulates: - Porosity - space between rock grains in which oil accumulates - Permeability - passage-ways between pores through which oil and gas moves Seal Rock - A rock through which oil and gas cannot move effectively (such as mudstone and claystone) Seal Rock - A rock through which oil and gas cannot move effectively (such as mudstone and claystone) Migration Route - Avenues in rock through which oil and gas moves from source rock to trap Migration Route - Avenues in rock through which oil and gas moves from source rock to trap Trap - The structural and stratigraphic configuration that focuses oil and gas into an accumulation Trap - The structural and stratigraphic configuration that focuses oil and gas into an accumulation

11 CPH Reservoir Sandstone Good Porosity = Lots of Space for Petroleum Pores (blue)

12 CPH Reservoir Sandstone Pore-Filling Cement Reduces Quality = Less Space for Petroleum Cement(pink)

13 CPH Directional Drilling Avoids Surface Hazards Gas Oil Water American Petroleum Institute, 1986

14 CPH Extended Reach Drilling Technology Advances Result in More Cost-Effective Wells Reduce friction Use geology to find stable path of least resistance Drill Mud reduces torque and drag Tri-cone Drill Bit Downhole Motor and Steering Assembly Logging Tool Torque Drag

15 CPH Completed Oil Well American Petroleum Institute, 1986 Water Drive - Hydrostatic pressure pushes oil and gas to surface Water Drive - Hydrostatic pressure pushes oil and gas to surface Gas-Cap Drive - Expansion of gas under pressure pushes oil to surface Gas-Cap Drive - Expansion of gas under pressure pushes oil to surface Dissolved-Gas Drive - Gas disseminated in oil; usually requires pumping Dissolved-Gas Drive - Gas disseminated in oil; usually requires pumping

16 CPH Secondary Recovery WaterGasSteamChemicalFire Pumped into the reservoir to force additional petroleum out of the pores in the reservoir rock InjectionWells Producing Wells Of 60% Remaining in Reservoir
