摘要： A method of determining changes in the boundary interface in a sub-surface oil reservoir between the to-be-recovered oil and a driveout fluid, such as steam, uses time-displaced gravity gradient measurements to provide an indication of the changes in the gravity gradient over time. The measured data are subject to a simulated annealing optimization to find the global minimum that best represents the observed values within the solution space. The optimization process includes establishing an appropriately constrained model of the oil reservoir and a quantized set of mathematically related parameters that define the model. Successive models are perturbed and evaluated from a figure of merit standpoint until a global minimum that best describes the measured time-lapse data is found.

摘要： Airborne gravity measurements may be added to the collection of airborne LiDAR so that it may be used to produce a digital elevation model (DEM), which may be used along with gravity data to produce an improved geoid, which may be used to produce an improved DEM based on the improved orthometric heights. A computing device may be configured to receive airborne navigation, gravity and LiDAR data, generate position information based on the navigation data, generate gravity field information based on the gravity data and the position information, generate orthometric height information based on the LiDAR data and the position information, and generate a geoid based on the gravity field and orthometric height information. The computing device may also generate a geoid model based on the gravity field and an existing DEM, and generate the orthometric height information based on the LiDAR data, position information, and geoid model.

摘要： A method of interpolation between a plurality of field gradient tensors including the steps of: accessing a plurality of field gradient data; formatting said plurality of field gradient data into 3-dimensional tensors of rank 2; determining a rotational matrix and a structural matrix for each tensor; interpolating said structural matrices; detecting errors in the raw data only apparent using the rotational component. interpolating said rotational matrices as quaternions on the surface of a unit 4-sphere; reconstructing said structural matrices and said rotational matrices to yield field gradient tensors at the interpolation points, wherein the interpolation is between two said field gradient tensors, the field gradient tensors being expressed as 3 x 3 matrices of values, each resolved into a rotational matrix and a structural matrix with three diagonal components.
