Title: Channel estimation device and method, demodulation device and method, and fading frequency decision device and method
Inventor: USUDA MASAFUMI
IPC: H04B1/707
Filed: 2000-03-31
Abstract: In this invention, a channel estimation value of data symbols of a data channel is calculated by weighting and averaging pilot symbols in a parallel time multiplexing method. Also, a channel estimation value of data symbols during each data symbol interval is calculated by dividing data symbols in a slot into a plurality of data symbol intervals, selecting pilot symbols suitable for calculation of a channel estimation value of data symbols during each data symbol interval and weighting and averaging that pilot symbols. Also, a fading frequency is detected based on an inner product value of pilot symbols.      Weighting factors are changed based on the detected fading frequency. Also, a channel estimation value is calculated by weighting and averaging pilot signals using a plurality of weighting sequences. The calculated channel estimation value is used to demodulate received data. The output data with the highest quality is selected by judging reliability of these plurality of demodulated data. It is also possible to select some weighting sequences based on the result of the reliability judgment of the demodulated data for predetermined period of time. In this case, after the selection, demodulation is performed by using these selected weighting sequences only.

Title: Method of modelling the production of hydrocarbons by a subsurface deposit which are subject to depletion
Inventor: LENORMAND ROLAND
IPC: E21B49/00
Filed: 2003-03-17
Abstract: The invention relates to a method of modelling the production of hydrocarbons comprising, for example, relatively-high-viscosity oils. According to the invention, measurements are taken in the laboratory of the respective volumes of oil and gas produced by rock samples from the deposit and the relative permeabilities (Kr) of the rock samples with regard to hydrocarbons. A gas fraction formation and flow model is used to determine a volume transfer coefficient (hv) by means of an empirical function which represents the distribution of nuclei that can be activated at a pressure P (function N(P)) which is set with reference to the preceding measurements. Assuming that the distribution of nuclei N(P) in the rocks of the deposit is the same as the distribution measured in the laboratory, the gas fraction formation and flow model is used to determine the numerical transfer coefficient which corresponds to same inside the deposit at selected depletion rates. In this way, the relative permeabilities can be predicted.

Abstract: Seismic traces of 3D surveys are interpolated using polynomials in 4D space from a less densely sampled real data set of source paints S(x,y) and receiver points R(x,y). Input seismic traces should be pre-processed by normal move out (NMO) and static corrections. Input traces contributing to each single interpolated trace are chosen from a selected number of traces closest to each interpolated trace in 4D space. The methodology in accordance with the invention is designed to minimize computational load. The amplitude of an interpolated trace is modeled with a two-term Amplitude vs. Offset (AVO) formulation.
