摘要： Determining parameters associated with a hydrocarbon bearing formation beneath a sea bed. At least some of the illustrative embodiments are methods including: obtaining data gathered regarding a plurality of distinct readings by sensors, the readings responsive to a source of electrical energy towed in water above the hydrocarbon bearing formation, the sensors sense an electrical parameter associated with the source; combining a first datum associated with a first path of travel of the source with a second datum associated with a second path of travel of the source, the second path of travel distinct from the first path of travel, and the combining creates a first combined datum; and determining the parameter associated with the hydrocarbon bearing formation by evaluating the first combined datum.

摘要： A system for detecting a location of a subsurface water channel includes an anchor electrode for disposal in a first body of water and a mobile electrode for disposal in a second body of water. An electric current source can be coupled to at least one of the mobile electrode and the anchor electrode to generate an electric current between the mobile electrode to the anchor electrode. A lead line can be coupled to the mobile electrode to enable the mobile electrode to move a distance in the second body of water. An ammeter can be coupled to the anchor electrode to measure the electric current from the mobile electrode. A processor can compare the current with the length of the lead line to determine the location of the subsurface water channel.

摘要： Resistivity measurements are made at a plurality of frequencies. An asymptotic high-frequency limit is determined and the electrical efficiency is estimated as a ratio of the high frequency resistivity limit to the low frequency resistivity. From the electrical efficiency, petrophysical parameters of a rock such as porosity and water saturation can be estimated.

摘要： A method for determining the variations of the resistivity index (RI) of a family of rock samples of complex pore structure with at least two pore networks, as a function of the water saturation (Sw), and in the presence of a non-oil conducting fluid. The volume fraction (f1, f2, f3) occupied by each pore network and the distribution of the pore throats in the various pore networks are determined for each sample of the family. The values of coefficients relating the variation of its electrical resistivity as a function of its water saturation (Sw) are experimentally determined on a sample of the family used as a reference sample. The resistivity index (RI) of all the samples of the family is then determined on the basis of the variation of parameters describing the layout of the pore network, and using the values of the coefficients measured on the reference sample. The method allows measurement of a continuous resistivity index curve which is not obtained, as in conventional techniques, from only a limited number of points at capillary equilibrium.

摘要： A method and apparatus for obtaining a resistivity measurement of an earth formation surrounding a borehole in an MWD device uses an electrode for injecting current into the earth formation and an electrode for obtaining a responsive signal from the borehole. The electrodes are located on the drill bit arm or blade. Measured resistivity values are obtained at the location of the drill bit. Measurements can be taken in both oil-based mud and water-based mud environments. Maximum or minimum resistivity can be used to best represent the resistivity of the surrounding formation.
