EOR Results

Delivering EOR Results

Improved Oil Production & Oil Cut Rates

The Seismic Stimulation™ Tool from Applied Seismic Research is delivering compelling Enhanced Oil Recovery results to oil and gas industry customers around the world, with significant improvements in oil production and oil cut, leading to improved return on investments for field operators.

Seismic Stimulation™ for Multiple Mature Oil Wells

Though the Seismic Stimulation™ Tool operates in a single abandoned well, it is not a single-well stimulation. The Tool’s coverage extends through fault blocks and layers to deliver Seismic Stimulation™ for wells within a radius of up to 1.4 miles.

No Environmental Impact or Well Damage

The Seismic Stimulation™ Tool is safe, with no damage to the well’s cement bond or any increase in fines migration. Emitting only seismic waves, it has no environmental impact.

Prime Candidates for Seismic Stimulation™

Will Seismic Stimulation™ work to Enhance Oil Recovery for your aging oilfield?

We cannot guarantee results, but we can share past successes and give you a picture of what types of oilfields are prime candidates for Seismic Stimulation™.

Seismic Stimulation™ has been proven in:

Carbonates
As found in the Permian Basin in the U.S. and in fields in the Middle East.

Sandstones
As found in United States, Canada, Mexico and North Africa.

Diatomites
As found in the U.S.

Seismic Stimulation™ works best in mature oilfields with:

  • Gas-Oil Ratio less than 2,000 scf/bbl
  • API Gravity higher than 13 Degrees
  • A high degree of heterogeneity and bypassed oil

EGYPT Belayim Field Multiple Formations

Single Standard Tool for 7” casing

The tool was installed in a well with perforations open in one set of perforations and offset wells, singly completed into other formations were monitored to study Seismic StimulationTM performance across vertical horizons.

Seismic StimulationTM effectively stimulated multiple horizons by passing high energy waves vertically through varied lithology as shown in the table below:

UNCONSOLIDATED SANDSTONE California Elk Hills Field

Single Standard Tool for 7” casing covers 6 Monitored Horizontal Production Wells

The operator selected to install a Seismic StimulationTM Tool in a watered-out area of the field. In this field the water drive moves from Northeast to Southwest and follows fault lines. The reasoning behind the installation was to study the efficacy of Seismic Stimulation to revitalize a completely watered out area of the field. The study monitored 6 dewatering wells whose purpose is to abate influx of the water drive and thus to slow down watering out of other areas of the field. Secondarily, to study the efficacy of Seismic Stimulation to cross fault blocks.

A map of the area is shown below:

  • 40 Bbls/D Results of the stimulation are remarkable:
  • 240 Bbls/D (400 %) Average historical oil production
  • 1% Average historical oilcut
  • 7% Peak average Seismic StimulationTM oilcut
