摘要： A control device (10) (or "bird") for controlling the position of a marine seismic streamer is provided with an elongate, partly flexible, body (12) which is designed to be connected electrically and mechanically in series with the streamer (14). In its preferred form, the bird has two opposed wings (24), which are independently controllable in order to control the streamers lateral position, as well as its depth.

摘要： In the exploration for underground hydrocarbon deposits it is helpful to obtain a measure of the elastic parameters of earth strata, for they are directly related to, and useful for characterizing, rock strength, porosity, lithology, and pore fluids. The elastic moduli of earth strata are also directly related to the acoustic propagation characteristics of the earth, and along with density constitute primary parameters of earth strata in seismology. One model for drawing useful information from seismic data involves the Christoffel relation, and so far there has been no known way of directly solving this relation exactly without use of approximations or weak anisotropy assumptions. The invention proposes a method of determining the elastic moduli of anisotropic earth strata using acoustic and density data without making simplifying approximations of the Christoffel relation or the assumption of weak anisotropy. To this end, it suggests that the relation be converted algebraically into a linear system and solved analytically to generate a solution for estimating elastic moduli. In a preferred embodiment of the invention, a set of qP phase points obtained from walkaway VSP data, with multiple vertical angles, plus at least one vertical Sv point, are used to derive the elastic moduli A11, A13, A33, A55. In the case of FTIV or other orthothrombic media, the present invention may also be applied to obtain additional elastic moduli.

摘要： A device for securing two or more seismic energy sources (7) at fixed relative positions during firing of the sources (7) consists of a rigid framework (6, 7) comprising end frames (6) and intermediate longitudinal bars (7). In order to provide an extremely light but at the same time completely rigid framework, the seismic energy sources (7) are used as longitudinal bars between the end elements (6).
