Brief summary
Introduction
As we know, failure to replace hydrocarbon reserves may negatively affect the petroleum business and world economics. Fortunately, new exiting possibilities in hydrocarbon reserves discoveries can prevent it.
One of them is BSE technology which initiates echo from oil/gas deposits and directly indicates hidden hydrocarbon reserves. This technology is completely different from seismics, as it produces data on absolutely different physical base and with better results . Seismic prospects are just reservoir images. BSE technology doesn't offer images, but gives data about presence and depth of the reserves as well as hydrocarbon field outline and also allows to find productive reserves in anticline structures as well as in stratigraphic, lithologic, tectonic and any other traps. Hidden hydrocarbon reserves in any traps is disclosed during passing a line profile under the traps. As a result, BSE technology significantly increases number of discoveries for the same area (because seismics usually doesn't define reserves in monocline blocks with sufficient reliability). It can mitigate shortage in hydrocarbon reserves in the future and greatly decrease exploration expense . The technology was successfully tested on 3000 km observation lines.
Physics
This Technology was patented in the USA in 2005 . Technology is based on new phenomenon in hydrocarbon deposits ( A. Berg. Method of Seismo-Electromagnetic Detecting of Hydrocarbon Deposit, US Patent № 7,330,790. October, 2005):
if electromagnetic and seismic pulses penetrates the deposits simultaneously (fig.3, .pdf file, below) we can record electromagnetic response from the deposits on the surface. An example of the response is shown in figs.6 and 7, the same file. This phenomenon is called Binary Seismo-Electromagnetic (BSE).
Technoogy
BSE technology has two modification – marine and on-land. Short electromagnetic and seismic pulses have about 100 kJ energy each. Electromagnetic source is long grounded cable, seismic source is special Sparker. Electromagnetic response from hydrocarbon deposits is detected by high-speed electrodes (marine modification of the technology is shown in fig.8, the same file ).
Specification(for any type of trap)
- Wildcatting success rates about 75%.
- Depth of investigation is up to 6 km.
- Resolution in thickness of commercial hydrocarbon deposit <0.005 H, where H is depth of the deposits.
- Error in determination of water-petroleum boundary position is < 50 m x (1+H/2).
- Error in determination of hydrocarbon deposit depth is < 150 m x (1+H/2).
- Productivity is >7 km per hour for marine surveys or > 10 km per day for on-land surveys.
- Power consumption is <50 kW.
Main tasks
- Commercial hydrocarbon reserves prognoses in traps of any type with high-probability.
- Detection of hydrocarbon deposit presence on the observation line over structure wings, monocline rocks and other geological objects.
- Outlining of the hydrocarbon deposits.
- Estimation of hydrocarbon deposits depth.
- Estimation of hydrocarbon reserves volume.
- Recommendation for drilling.
Expected main result
The technology can help to discover hydrocarbon fields in less time and money on old and new provinces (offshore and onshore). It is may be expected to hold recent oil/gas production for many years.
BSE technology can be demonstrated any time on well-known fields and new blocks world-wide.
