摘要： There is provided a method for modeling a hydrocarbon reservoir that includes generating a reservoir model that has a plurality of coarse grid cells. A plurality of fine grid models is generated, wherein each fine grid model corresponds to one of the plurality of coarse grid cells that surround a flux interface. The method also includes simulating the plurality of fine grid models using a training simulation to obtain a set of training parameters, including a potential at each coarse grid cell surrounding the flux interface and a flux across the flux interface. A machine learning algorithm is used to generate a constitutive relationship that provides a solution to fluid flow through the flux interface. The method also includes simulating the hydrocarbon reservoir using the constitutive relationship and generating a data representation of a physical hydrocarbon reservoir in a non-transitory, computer-readable medium based on the results of the simulation.

摘要： The invention is a method for extrapolating missing near-offset seismic data (101) so that the data may be used, for example, in SRME or another multiple-reflection elimination method. The invention uses the reciprocity principle (102) to relate two seismic states (acoustic or elastic) that can occur in a time-invariant, bounded domain in space. One of these states represents the physical experiment for the acquisition of the actual seismic data where near-offset traces are missing, and the other state represents a synthetic experiment with no missing near offset traces, computer-generated on a much simpler earth model. The reciprocity relationship used to relate these two states is iteratively inverted for the missing near-offset traces (103), preferably using only part of the synthetic data (102) so as to reduce inversion artifacts. The reference model acts as a constraint on the near-offset extrapolation.

摘要： Method for quantitatively assessing connectivity for well pairs at varying frequencies. A time series of measurements (12) is chosen for each of the two wells such that the particular measurements will be sensitive to subsurface connectivity if it exists (11). The two time series may then be pre-processed by resampling to time intervals commensurate with response time between the two wells (13), detrending the measurements (14), and detecting and eliminating spiking noises (15). Then the time series are transformed to the frequency domain where coherence and phase between the two series are compared for varying frequencies (16). This comparison is used to make a determination of connectivity.

摘要： There is provided a method for modeling a hydrocarbon reservoir that includes deriving a computational mesh on a fine unstructured mesh using a multilevel mixed multiscale finite volume (MMMFV) method. Deriving the computational mesh includes computing a first algebraic multilevel basis function for a pressure, constructing an interaction region, and generating a primary mesh. A second algebraic multiscale basis function for a velocity approximation is computed and the primary mesh is discretized. The hydrocarbon reservoir is simulated using the computational mesh. A data representation of a physical hydrocarbon reservoir is generated in a non-transitory, computer-readable, medium based at least in part on the results of the simulation.

摘要： A method of separating petroleum samples containing a hydrocarbon-soluble elemental species of interest to facilitate analysis of an elemental and/or isotopic signature. A petroleum sample is mixed with a demulsifier and separated, for example by centrifuging, into one or more intermediate organic fractions. The intermediate organic fraction(s) are mixed with a solvent such as water and a second demulsifier, then separated into one or more prepared organic fractions and one or more solvent-based fractions. Some or all of the resulting fractions are then stored for possible further processing. Optionally, the petroleum sample may be spiked with one or more of an organic standard and an inorganic standard, and the solvent may likewise be spiked with an inorganic internal standard, to facilitate later analysis.

摘要： A method for performing a simulation of a subsurface hydrocarbon reservoir is disclosed. Each cell in a reservoir model has an equation set representing a reservoir property. A stability limit is determined for each cell. Each cell is assigned to an explicit or implicit formulation. A solution to the system of equations is solved for using an initial guess and an explicit or implicit formulation. A stability limit is calculated for the converged cells. When the number of unconverged cells is greater than a predetermined amount, a reduced nonlinear system is constructed with a list of unconverged cells. The reduced nonlinear system is solved with the implicit formulation, and other cells are solved with the explicit formulation. Parts of the method are repeated until all equation sets satisfy a convergence criterion and a stability criterion, and the solved solution is output.

摘要： Method for reservoir surveillance using a three-dimensional Earth Model (101) to improve and expedite the surveillance at all scales of investigation (field, reservoir, fault compartment, and individual well) and at all time steps (minutes, hours, days, months, years). The new method allows users to rapidly identify anomalous field and well performance (109) and provides capability to investigate root causes of the performance deviation from predicted (110). Animated co-rendered displays (107) of the earth model and actual (104) and simulated (105) production data enable the user to interactively determine model adjustments back at the basic level of the Earth Model, which are then propagated to a geologic model (102) and then to the reservoir simulator (103) to update it (111) in a physically constrained way.

摘要： Method for efficient computation of wave equation migration angle gathers by using multiple imaging conditions. Common reflection angle or common azimuth gathers or gathers including both common reflection angles and common azimuth angles are produced as the data are migrated. In the course of either wave equation migration or reverse time migration, the pressures and particle motion velocities that need to be computed are sufficient to also compute the Poynting vector pointing in the direction of source-side (35) or receiver-side (37) wavefield propagation. From that, the reflection and azimuth angles can be computed (38). The seismic images can then be stored in the appropriate angle bins, from which common reflection angle or azimuth data volumes can be assembled (39).

摘要： The invention is a method for inferring the saturation and pressure change of a reservoir by combining the information from 4D (time-lapse) seismic and time lag data volumes (7) derived from the 4D seismic, well logs (4), and reservoir simulation results (when simulator results are available) and featuring one or more 4D well ties (1) for a quantitative 4D interpretation. The inventive method uses model-based inversion incorporating rock physics (2) at well locations (5), and is statistical-based (6) away from wells. The method thus allows integration (8) of rock physics model and reservoir simulation and honors 4D seismic change.
