<p>A method of determining the absolute orientation and attitude of seabed nodes used in electromagnetic sensing of hydrocarbon reservoirs, or seabed logging. The data from a series of acoustic, rotational rate, acceleration, and pressure sensors is integrated using a Kalman filter based software. The method allows for the determination of the depth of the seabed node, the attitude of the seabed node, and the orientation of an imaginary straight line drawn between the ends of the legs of the seabed node.</p> |
