摘要： Systems and methods of predicting reservoir quality can include measuring properties of a subsurface reservoir. Based on the measured properties of the subsurface reservoir; a modeling grid and domain representing a sediment textural framework of a subsurface reservoir are initialized. Deposition of sediments during the time period is predicted using a depositional model. The modeling grid and domain are updated based on the predicted deposition. The modeling grid and domain is transferred from the depositional model to a diagenetic model. The sediment textural framework of the area's subsurface is updated using the diagenetic model to simulate physical and chemical changes to deposited sediments during the time period. The modeling grid and domain is stored and a test well can be drilled based on the modeling grid and domain.

摘要： A global objective function is initialized to an initial value. A particular model simulation process is executed using prepared input data. A mismatch value is computed by using a local function to compare an output of the particular model simulation process to corresponding input data for the particular model simulation process. Model objects associated with the particular model simulation process are sent to another model simulation process. An optimization process is executed to predict new values for input data to reduce the computed mismatch value.

摘要： An elemental analysis of rock samples from outcrop sections or wells is performed. Data quality checks, data analysis, and filtering are performed on the rock samples, including de-spiking of elemental profiles and elemental ratios. First and second derivatives for the elemental profiles and the elemental ratios are calculated. Samples and depths that exceed thresholds are determined. The process is repeated for the elemental profiles and the elemental ratios that are related with boundary determination and carbonate or siliciclastic sediments. Additional filters are applied to at least a subset of the elemental profiles and elemental ratios that are related with boundary determination and carbonate or siliciclastic sediments to enhance the boundary identification. Possible boundaries in depths of the outcrop sections or wells are determined by summarizing the additionally filtered elemental profiles and the additionally filtered elemental ratios.

摘要： A method related to generating a facies-cement model of a subsurface region. The method includes obtaining depositional data regarding the subsurface region, wherein the depositional data incudes wave impact data. The method further includes generating, by a computer processor, a geological model for the subsurface region using a forward-depositional modeling process and the depositional data, wherein the geological model comprises wave energy data. The method further includes determining, by the computer processor, carbonate cementation data for the subsurface region using a diagenetic modeling process and the wave energy data, wherein the carbonate cementation data describes cementation in one or more depositional processes, and generating, by the computer processor, a facies-cement model of the subsurface region.

摘要： A method of enhancing a gross depositional environment (GDE) map of a subsurface formation. The method includes obtaining the GDE map of the subsurface formation, including a lithology map of a plurality of lithotypes and obtaining a paleo-bathymetric map of the subsurface formation. The method further includes assigning an inverse mobility for each of the lithotypes and determining, using a computer processor, an enhanced GDE map based, at least in part, on the GDE map, the paleo-bathymetric map, and the inverse mobility for each of the lithotypes.
