摘要： A system has been invented for producing a final earth model of part of an earth formation having N (one or more) layers, the method including, in one aspect, generating an initial earth model based on raw data produced by a wellbore logging tool at a location in a borehole through the earth, performing 2-D forward modeling on the initial earth model to produce an interim earth model that includes a set of synthetic tool responses data for the wellbore logging tool, comparing the synthetic tool response data to the raw data to determine whether there is misfit between them; if misfit between the synthetic tool response data and the raw data is acceptable, saving and storing the interim earth model as the final earth model; if misfit between the synthetic tool response data and the raw data is unacceptable, performing 1-D forward modeling N times on the interim earth model, producing a secondary earth model; performing 1-D inversion on the secondary earth model; and either saving the secondary earth model as the final earth model or re-subjecting the secondary earth model to 2-D forward modeling and subsequent misfit comparison. In one aspect the data is overcorrected following the N times 1-D forward modeling step. In one aspect the N times 1-D forward modeling step is accomplished by using a look-up table of stored values for synthetic tool responses. In one aspect the N time 1-D inversion step is accomplished by using such a look-up table.

摘要： A method for determining formation resistivity anisotropy in a wellbore environment. The method of the present invention effectively extends the dynamic range of the existing well logging service of the multi-component induction tool, allowing the use of this service in wells drilled with conductive WBM systems. A sequential inversion processing of galvanic array lateral log HDLL/MLL data or DLL/MLL and also multi-component induction log (3DEXSM) data is used. The formation resistivity structure of the near wellbore environment is determined using the galvanic measurements of the array lateral log tool. The formation resistivity anisotropy of the undisturbed zone is determined using the result of the inversion of the galvanic array data and inversion of measurements of the multi-component induction tool

摘要： Different subsets of multiarray resistivity measurements are inverted using a corresponding resistivity model. The models are selected based at least in part on the resolution of the measurements. Results of the inversion are combined to give a single model consistent with the resolution and depth of penetration of each subset of the multiarray data.

摘要： A method is disclosed for real-time (well-site) resistivity anisotropy determination using array lateral logs or any other unfocused, lateral-type measurements, and array induction logs or any other focused, induction-type measurements. Near-vertical wells with a deviation angle of less than 30 degrees are considered. Since with a lateral log, at each logging depth the injected current has both horizontal and vertical components, the data contains information related to both horizontal (Rh) and vertical (Rv) resistivities. With array induction tool, the induced current in near-vertical wells has only a horizontal component, and the induction data contain information related to Rh only. Having those two data sets acquired in the same well, it is possible to instantly estimate the formation resistivity anisotropy using square of a ratio between borehole and invasion corrected lateral and induction focused logs.
