    摘要: An optical analyzer (14) for performing spectral analysis on an optical beam (18) includes an optical filter (28), a mover (30), an optical launcher (36), and an optical receiver (38). The optical filter (28) includes a filter area (46) that is a narrow band pass type filter having multiple alternative center bandwidths that are distributed along the filter area (46). The mover (30) moves the optical filter (28). The first optical launcher (36) directs the optical beam (18) at the filter area (46) so that the optical beam (18) is near normal incidence to the filter area (46). The optical analyzer (14) can be used to simultaneously monitor multiple optical signals. Additionally, the optical analyzer (14) can include a beam redirector (40) that causes the optical beam (18) to make two passes through the optical filter (28).

    摘要: Method for determining best and worst cases for values of model parameters such as porosity and shale volume fraction generated by non-unique matrix inversion of physical data such as seismic reflection amplitudes. The matrix is diagonalized, and then orthonormal basis vectors associated with insignificant diagonal elements are used to generate upper and lower bounds on the solution. Best and worst case solutions are determined as linear combinations of the null basis vectors, where the expansion coefficients are determined by making a best fit to the upper and lower bounds.

    摘要: To support interleaving of optical channels and to provide sufficient isolation between such interleaved channels, a circulator (60-62) receives, on an optical fiber (16-18), a broadband signal containing a plurality of adjacent channels. The circulator selectively routes the broadband signal through a filter (64, 66) to isolate, on an individual basis, at least one desired channel. A filtered signal, corresponding to the at least one desired channel, is then output from the filter (64-66) and reflected back into the filter by a mirror (68-70) such that the at least one desired channel is subjected to a second filtering process that further improves isolation of the at least one desired channel. Following this second filtering process, the at least one desired channel is applied to the circulator (60-62) for re-inserting into the optical fiber (16-18), as illustrated in FIG. 6. To mitigate the effects of four-wave mixing in each bidirectional optical fiber, a channel assignment plan ensures that pairs of adjacent channels are assigned on a mutually exclusive basis to at least one of an up-link and a down-link direction.

    摘要: Method for constructing an integrated rock physics model that simulates both shale anisotropy and stress-induced anisotropy of clastic rocks. In the model, the total pore volume is divided into three parts according to the estimated shale volume and effective stress: (1) clay-related pores, (2) sand-related pores, and (3) microcracks (mainly in the sand component). The pore space is then partitioned into the clay-related and sand-related pores using a scheme first disclosed by Xu and White in 1995. The model simulates shale anisotropy via the preferred orientation of clay-related pores and stress-induced anisotropy via the preferred orientation of microcracks, which is controlled by the differential stresses. Laboratory measurements or well logs are needed to establish a relationship between crack density and the effective stress.
