摘要： Measurements made with a multicomponent logging instrument when used in a substantially horizontal borehole in earth formations are diagnostic of the direction of beds relative to the position of the borehole. When the logging instrument is conveyed on a drilling assembly, the drilling trajectory may be maintained to follow a predetermined trajectory or to maintain a desired distance from a boundary such as an oil-water contact.

摘要： Data are acquired using multi-array logging tool in a borehole having an angle of inclination to a normal to the bedding plane of earth formations. The multi-array measurements are filtered using angle dependent filters to give a filtered curve corresponding to a target one of the multi-array measurements using angle dependent filters. Correlation coefficients are determined for a set of possible dip angles and a relative dip angle is estimated from the correlation coefficients. This dip angle estimate together with bed boundaries obtained from the multi-array measurements are used for inverting multi-component measurements alone or jointly with multi-array measurements to refine the relative dip angle interpretation and give horizontal and vertical formation resistivity.

摘要： Measurements made by a cross-dipole acoustic logging tool in a borehole are processed to determine the principal directions of azimuthal anisotropy of a subsurface formation. Measurements indicative of azimuthal resistivity variations are also made with a multicomponent induction logging tool. These electrical measurements are processed using the principal direction determined from acoustic measurements to give an estimate of azimuthal resistivity variations. Based on modeling results, azimuthal resistivity variations are interpreted to estimate a fracture depth in the rock for known fluids therein.

摘要： A fast, efficient and accurate pseudo 2-D inversion scheme for resistivity determination of an anisotropic formation uses data from a tool (3DEX) comprising three transmitters and three corresponding receivers sampling the formation in a plurality of spatial directions. An initial model of the formation including invasion zones is obtained using a conventional multifrequency and/or multispacing logging tool. A pseudo 2-D inversion scheme combines an accurate full 2-D forward solution of the synthetic responses of the earth model with a 1-D approximation of the sensitivity matrix of the horizontally layered anisotropic background model. The timesaving compared to a regular 2-D inversion scheme can be tremendous. The applicability of this scheme is important in cases when borehole and near-zone effects do not allow an interpretation based on 1-D inversion. A comparison of the pseudo 2-D inversion scheme versus a full 2-D inversion using a realistic synthetic example shows that the pseudo 2-D inversion scheme performs as well as the full 2-D inversion, but in a much shorter time.
摘要翻译：用于各向异性形成的电阻率确定的快速，有效和准确的伪2-D反演方案使用来自包括三个发射器和三个对应的接收器的工具（3DEX）的数据，该三个发射器和三个对应的接收器在多个空间方向上对地层进行采样。使用常规的多频和/或多分段测井工具获得包括入侵区的地层的初始模型。伪2-D反演方案将地球模型的合成响应的准确的全2-D向前解与水平分层各向异性背景模型的灵敏度矩阵的1-D近似相结合。与普通2-D反演方案相比，时间可以是巨大的。当井眼和近区效应不允许基于1-D反演的解释时，该方案的适用性是重要的。使用实际的合成实例，伪2-D反演方案与全2-D反转的比较表明，伪2-D反演方案与完整的2-D反转相同，但是在更短的时间内。
