Basic Petroleum Geology Shell Technology Webcast 28 September 2006
Slide 5: Reservoir Rock (or "Swiss Cheese"!)
Reservoir Rock (or “Swiss Cheese”!) porosity permeability Space Ease to flow Between Between grains grains Low High Pressure Pressure Sand grains Shell Technology Webcast 28 September 2006
Slide 6: Oil getting left behind…
Oil getting left behind… EOR target Trapping mechanisms: (1) Surface tension traps oil drops (2) Less viscous water “short circuits” more viscous oil Shell Technology Webcast 28 September 2006
Slide 7: Combating trapped oil
Combating trapped oil Reduce surface tension Reduce viscosity contrast Thermal Steam injection EOR Miscible Gas injection Flood e.g. CO2 Chemical Surfactant in water Polymer in water Injection Selection of best technique requires detailed reservoir modelling and analysis Shell Technology Webcast 28

Slide 15: Qarn Alam Steam Injection - pilot
Qarn Alam Steam Injection - pilot Producer Observation well Steam injector Shut-in Producer Pi lo t Station Fractured Carbonate Viscous Oil Shell Technology Webcast 28 September 2006
Slide 16: Qarn Alam Steam Injection
Qarn Alam Steam Injection World’s largest thermal Gas Oil Gravity Drainage STEAM Oil, Gas and Water Fractures fill with water and gas … … while oil remains in matrix blocks … steam injected into the fractures will reduce oil viscosity and increase drainage rate of oil from rock matrix Fracture GOC O
