VSIT, Vibrating Brown FieldsNet Importer Oil & Gas Crisis and

Solutions

2

VSIT is a non-chemical way of introducing energy into the reservoir by means of seismic vibrations.

TECHNOLOGY DESCRIPTION

It reduces internal reservoir static friction by means of vibration. There is a well knownrelationship in Physics between friction and vibration. VSIT plays on that principle.

IOR TECHNOLOGY

VSIT is a technology for enhancing / improving oil recovery.

Produce un-recoverable oil.

Applicable synergistically with other primary, secondary, and tertiary recovery technologies.

Vibration can be repeated every year depending on field performance.

Optimum oil field specifications :• High water cut.

• Recovery factor less than 50%.

• Proven repeatedly in Indonesian Sandstone reservoir(s).

• On-shore & near shore.

• Specific gravity : 20 – 38 deg. API.

• At least 10 wells in the field.

• Well pad 50 meters from community housings to prevent noise disturbance.

• Optimum reservoir depth less than 7000 ft.

• In Waterflood field, VSIT can reduce water cut and water injection.

Field 5 : 4 wells; 3000 – 3500 ft depthField 5 : 4 wells; 3000 – 3500 ft depth

TREATMENT RESULTS

Production increase can be immediate or as late as 6 months.

Estimated production increase is 10 - 30% above baseline for approximately 1.5 years.

Watercut will decrease at some wells, ranging from 2% to 60% of the original.

Fluid level in the wellbore will increase between 10 –800 ft on some wells depending on quality of the reservoir. Pump resizing or increasing SL / SPM for beam pump can be done to pump off the well. Frequent monitoring of fluid level is critical to respond to immediate fluid level changes.

Oil composition will change as shown in the chromatography analysis. Usually additional heavy fractions are detected after the treatment.

16

TREATMENT RESULTS

Reservoir response is depending on type of reservoir, quality, depth, and remaining reserves.

Treatment range is around 3 kilometers radius but can be more, depending on the geological situation.

Shut-in wells / observation wells can be re-produced when there is a decrease in watercut.

Opening tighter zone(s) is recommended since it can be an oil productive interval after vibration.
