Sensitivity study and inversion of the fully-triaxial induction logging in cross-bedded anisotropic formation
نویسندگان
چکیده
We developed a three-dimensional finite-difference codes which can simulate the fully triaxial induction tool in a stratified, cross-bedded anisotropic formation. The sensitivity of the fully triaxial induction measurements in cross-bedded anisotropic formation is studied for the first time. The results show that the tensor measurements are sensitive to the formation resistivity anisotropy, formation structural dip as well as formation stratigraphic dip. A nonlinear least square minimization algorithm has been developed to determine the formation parameters in such a situation.

1-d Inversion of Triaxial Induction Logging in Layered Anisotropic Formation
In this paper, we present a one-dimensional (1-D) inversion algorithm for triaxial induction logging tools in multi-layered transverse isotropic (TI) formation. A non-linear least-square model based on Gauss-Newton algorithm is used in the inversion. Cholesky factorization is implemented to improve the stability and the reliability of the inversion. Zero-D inversion is conducted at the center o...
متن کاملimulation of full responses of a triaxial induction tool n a homogeneous biaxial anisotropic formation
Triaxial induction tools are used to evaluate fractured and lowresistivity reservoirs composed of thinly laminated sand-shale sequences. Thinly laminated and fractured reservoirs demonstrate transversely isotropic or fully anisotropic biaxial anisotropic electrical properties. Compared to the number of studies on transverse isotropy, relatively little work covers biaxial anisotropy because of t...

Middle to Upper Triassic (Upper Ladinian to Lower Carnian) deep-sea sedimentary rocks crop out across a large area west of Nakhlak village, Central Iran and have been named Ashin Formation. The up to 304m thick, turbiditic, siliciclastic Ashin Formation consists of alternating turbiditic, thin- and medium-bedded calcareous sandstones, purple, fine-grained volcaniclastic sandstones, and mostly g...
متن کاملInductive Source Design for Inductive Fracture Detection
Traditional inductive logging uses sources whose focussing input waveform does not change with borehole position. While this arrangement facilitates hardware design, the resolution which it provides varies from formation to formation, and is only accidentally optimal for any given sound position. Optimization theory provides a method for designing a distributed inductive borehole source array ,...
