Latest Patents

Qiwei Zhan holds a patent titled "Method for determining properties of a thinly laminated formation by inversion of multisensor wellbore logging data." This patent describes a method for determining properties of a laminated formation traversed by a well or wellbore. The method employs measured sonic data, resistivity data, and density data for an interval of interest within the well or wellbore. A formation model is derived from these measured data, representing the laminated formation as first and second zones of different rock types. The model is used to derive simulated data, which, along with the measured data, refines the formation model and determines properties such as porosity and saturation profiles.
