3 Primary Recovery Secondary Recovery Tertiary Recovery ChemicalThermalGas

4 Primary Recovery Secondary Recovery Tertiary Recovery ChemicalThermalGas

5 IOR BY CHEMICAL FLOOD Never really took off the ground for the past two decades: - Reasons? n Sensitivity to oil price n Large up-front investment n Unpredictable return on investment

6 However, n Extensive lab evaluations support the feasibility of chemical flooding n Field data proves chemical flooding is an effective way to recover residual oil n New chemicals and processes open the door for new opportunities

7 HOW TO REACH SUCCESS?

8 n S elect the proper project n U tilize the expertise of all involved n C hemical optimization n C ost efficiency n E valuate the lab results n S elect the best process n S tart the project

23 ASP - POTENTIAL PROBLEMS? After extensive ASP flood in China, results were successful, however: After extensive ASP flood in China, results were successful, however: n Alkali causes corrosion of the equipment n Scale forms in the formation n Produced wells plugged and require fracturing treatment to produce oil again n Alkali is detrimental to polymer viscosity n Extra polymer, NaOH and maintenance costs SPE 71492, 71061

24 ASP LASP ASP LASP n Combines the advantages of ASP and SP n Use 0.1 – 0.6% alkali n Reduces surfactant adsorption n Reduces polymer degradation n Reduce the maintenance cost n Reduce the scale formation n Reduces the total cost of the treatment

25 ASP vs. LASP Common ASP: 0.1% surf. / 1.0% NaOH Common LASP: 0.1% surf. / 0.2% NaOH ASP vs. LASP Common ASP: 0.1% surf. / 1.0% NaOH Common LASP: 0.1% surf. / 0.2% NaOH ASPLASP AS, $ / bbl $0.63$0.29 Polymer Cost Due to NaOH $$$ $$$$ Equipment Corrosion $$$ $$$$ Scale Formation $$$ $$$$
