  • High-resolution seismic acquisition device
    Patent number: 6366536
    Abstract: The invention relates to a seismic acquisition device in a marine environment. The device comprises a Janus Helmholtz (12) transducer which is able to operate at a large depth of immersion and to sound waves in a wide frequency band, a calculator (13) to program at will the frequency band and the form of the sound waves emitted by the transducer, a power amplifier (14) that can control the transducer in order to provide the emitted sound waves with predetermined power levels, an impedance adapter (16) placed between the transducer (12) and the amplifier to enable wide band and power adaptation, and a receiver (18) to capture the seismic waves reflected by the different layers of the sea bed.

  • Method for charting drillable zones in an oilfield avoiding anomaly zones
    Patent number: 6101446
    Abstract: The charting method consists in realising a recordings acquisition, constituting on the basis of the recorded seismic traces, a 3D seismic block (X, Y, T) sampled in elementary cells (C.sub.ijk), such that each elementary cell contains a sample (k) of a central seismic trace (TR.sub.ij), calculating for each elementary cell (C.sub.ijk) of the seismic block, the energy thereof, and fixing an energy threshold beyond which the presence Tk of anomaly zones is considered probable, selecting cells of the block which have energy equal or superior to the said threshold, coding the selected cells, such that all the cells belonging to a same contiguously selected cell set have the same code and the selected cells belonging to distinct contiguously selected cell sets have different codes, and effecting an XY projection of the coded cell block.

  • Hydrocarbon extractor
    Patent number: 5259958
    Abstract: A hydrocarbon extractor, intended to be disposed above a tank (10) containing a mixture of a liquid and a liquid hydrocarbon, comprises a belt (16) made of an oleophilic material which is adapted to be immersed in the mixture and two oleophilic rollers (26, 28), disposed one on each side of the belt, for recovering the liquid hydrocarbon from the belt. The rollers are rotated in an opposite direction to that of the movement of the belt and at a higher speed than the belt to enhance the recovery process.
