STEAMFLOODING THE FUTURE

GLOBAL OIL DEMAND

Oil and gas market ripe for breakthroughenhanced oil recovery solution:

World oil consumption rate at ! millionbarrels per day

"#$ production increase over ne%t "! yearsto meet pro&ected demands

'arket stability re(uires )!* annualinvestment to +,+!

Oil produced faster- less e%pensive and ithless disturbance to environment frome%isting ells

/OR can prolong life of oil fields up to $,years hen employed on 0proven1 reserves

2ig. ". 3lobal oildemand has gronfrom 4, millionbpd to over +million bpd in thelast ten years.

ACTUAL FACTS

5early to6thirds of the orld7s energy comesfrom oil and natural gas.

Oil and natural gas account for 0virtually alltransportation fuel in the 8nited 9tates1- andcivilied orld.

;he orld has taken the availability of oil andnatural gas for granted- and e%pects them to beaffordable.

ENHANCED OIL RECO-ER. /EOR0

*y definition- enhanced oil recovery is0;he third stage of hydrocarbon productionduring hich techni(ues that alter the

original properties of the oil are used1.

?n the case of 9team 2lood- its purpose isto restore formation pressure and to

improve oil displacement or fluid flo inthe reservoir.

UNDERSTANDING EOR

;he thermal processes @steam in&ectionAhave the greatest certainty of success andpotential applications in about 4,B of

enhanced oil recovery orldide.

;hermal methods also provide the highestrecoveries at the loest costs

UNDERSTANDING EOR

;he best application for 9teamflooding is:

a ell that is less than !-,,, ft deep-

heavy oil ith a viscosity less than ",-,,,centipoises-

and a soil permeability greater than +,, md.

UNDERSTANDING EOR

/nhanced Oil recovery techni(ues

can prolong the life of an oil fieldby as much as +! to $, years.

EOR PROGRAMS

9teamflooding is a proven enhanced oilrecovery method- used by many of thema&or oil companies.

2or e%ample- Occidental =hemical=ompany maintains a very successful /ORprogram- producing appro%imately $!,-,,,barrels of oil e(uivalent @*O/A per day from

/OR operations.

GREATEST STEAMFLOOD OPERATIONS

=anada7s ;ar 9ands pro&ect in lberta uses9teamflood systems for heavy oil production.

Oman is e%panding its massive 9teamfloodoperation.

Russia7s reserves in 9iberia re(uire 9teamflood

systems for increased production.
