摘要： Methods, systems, and devices for characterizing a water-flooded zone in an earth formation resulting from injection of water to the formation through an injector well borehole intersecting the formation. The method includes estimating horizontal elongation of the water-flooded zone using a gravity field change in the injector well borehole. Estimating horizontal elongation may include predicting a gravity field change for each of a plurality of model water-flooded zones for the borehole, wherein each model water-flooded zone is an elliptical cylinder having finite height and semi-axes; and fitting the gravity field change to one of the predicted gravity field changes corresponding to one of the plurality of elliptical cylinder model water-flooded zones. The gravity field change may comprise a difference between a first estimated gravity field in the injector well borehole before injection and a second estimated gravity field in the injector well borehole after injection.

摘要： A method for performing a gravity gradiometer survey of a surveyed region of terrain comprises providing an aircraft (e.g. jet) with a gravity gradiometer; flying said aircraft over said terrain at a speed of at least 100m/s and at an average height above said terrain of above said terrain of at least 300m; and collecting gravity gradient data for said surveyed region of terrain from said gravity gradiometer, said gravity gradient data comprising data for at least one component of the gravity gradient tensor. The spacing between flight lines in the survey flight pattern may be at least 300m. The aircraft may also carry a gravimeter, and the data from the gradiometer and the gravimeter may be combined. A model of the surveyed region is generated by fitting a prediction of a model to the gravity and gravity gradient data, wherein said fitting models a bandwidth or noise of one or both of the gravity and gravity gradient data. The gradiometer may be a superconducting gravity gradiometer.

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 estimating one or both of compaction or subsidence of a subterranean formation with gravity measurements. The free air gradient at surface is measured and compared with gravity measured in a borehole that intersects the formation. At a later point in time, values for gravity are re-measured, differences between the measured values at the initial point in time, and the later point in time are estimated. The differences are used to estimate the compaction or subsidence. A gravimeter can be used for measuring gravity, markers in the formation can be used in conjunction with the gravimeter.

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.
