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

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

22. LOW ALKALI SURFACTANT POLYMER FLOOD (LASP)

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

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

25. ASP vs. LASP Common ASP: 0. 1% surf. / 1. 0% NaOH Common LASP: 0
