    Abstract: Apparatus and associated methods relate to computerized system for predicting the quantity of oil and/or gas production at an oil site, where a prediction curve for oil and/or gas data transitions from a first fitted curve (e.g., a hyperbolic decline curve) to a second fitted curve (e.g., an exponential decline curve) at a transition point, the transition point being determined by progressively/iteratively identifying curvature changes in the first fitted curve over an initial time period by comparing a running list of terminal decline rates (Dmin) with a predetermined curvature threshold, and setting the occurrence of the transition point at the point where the rate of change of the terminal decline rate is less than the predetermined curvature threshold. In an illustrative example, the second fitted curve may use the value of Dmin that minimizes the deviation between successive forecasts.

  • Patent number: 10428631
    Abstract: A method is for use with subterranean formations, such as oil and/or gas reservoirs. In some examples (e.g., production examples), the method improves the production from that formation. Some of the examples of the method describe selecting both an exertive force (e.g., a pressure) to apply at a wellbore, but together with a drawdown pressure at the wellbore to modify operations (e.g., improve production) at that subterranean formation. The selection of one or both of the exertive force and drawdown pressure may be based on the downhole environment at that wellbore, which can include the porosity and/or permeability of a near-wellbore formation radially surrounding a wellbore. The exertive force and drawdown pressure may be specifically selected to modify the porosity and/or permeability of the near-wellbore formation.

Such methods may be particularly useful when interpreting large sets of data, such as DAS VSP data collected during hydrocarbon recovery operations. The methods generally involve identifying data channels affected by noise from a DAS data set, and then interpolating from the surrounding data. This may improve the quality of the resulting downsampled data, with respect to the signal to noise ratio, compared to what would have occurred by merely decimating unwanted data channels. In addition, a priori information about channel fading, the desired downsampling rate, and the slowest expected elastic waves may be used to filter the DAS data.

  • Patent number: 10012056
    Abstract: Apparatus and associated methods relate to a decline curve analysis method for predicting oil and gas production from an oil well, where a prediction curve for oil and/or gas data transitions from a first characteristic function to a second characteristic function at the bubble point. In an illustrative example, the first and second characteristic functions may be of the monotonically decreasing type. A distinction between the two characteristic functions may be that the absolute value of the decline for the second characteristic function is greater than or equal to the absolute value of the decline of the first characteristic function for each value of time and/or cumulative oil/gas past the bubble point. In various embodiments, the method may give more accurate predictions for oil and/or gas production once the stimulated reservoir volume reaches the bubble point.

  • Patent number: 10012761
    Abstract: A computer accepts dead-oil properties of a reservoir fluid sampled from a well. The dead-oil properties are the measured composition of the reservoir fluid after volatile components of the reservoir have substantially vaporized. The computer analyzes the dead-oil properties and a constraint to produce estimated live-oil properties of the reservoir fluid. The live-oil properties are the composition of the reservoir before the volatile components have substantially vaporized. The computer uses the estimated live-oil properties to make a decision regarding the well.

  • Patent number: 9915965
    Abstract: Systems and techniques are disclosed for flexible, secure energy management that enable control of individual devices in a customer site's energy infrastructure, which can allow optimization (e.g., by minimizing energy cost or usage) across the infrastructure. A system management component may centralize optimization and control capabilities across the energy infrastructure by determining an energy model and directing consumption, storage, and energy draw activities for the totality of the energy infrastructure devices. Systems may include modular, secure terminal devices that can be attached to or paired with the devices in an energy infrastructure in order to provide input data such as power load metrics, as well as to control the operation of the devices. A dynamic, adaptive prediction of system parameters, such as future demand, cost, generation capacity, and other metrics, may be provided. Dynamic, adaptive prediction may be performed without detailed historical usage data.

  • Patent number: 9835012
    Abstract: System and methods of simulating fluid production in a multi-reservoir system with a common surface network are presented. An equation of state (EOS) characterization of fluids is matched with a delumped EOS model representing different components of the fluids for each reservoir within the multi-reservoir system. Fluid production in the multi-reservoir system is simulated for at least one simulation point in the common surface network, based in part on the delumped EOS model for each reservoir. If the fluids produced during the simulation at the simulation point are mixed fluids from different reservoirs, one or more interpolation tables representing the mixed fluids are generated and properties of the mixed fluids are calculated based on the generated interpolation tables. Otherwise, the properties of the fluids are calculated using the delumped EOS model corresponding to the reservoir from which the fluids are produced.

  • Patent number: 9835763
    Abstract: The method of monitoring carbon dioxide leakage in carbon capture and storage reservoirs estimates porosity and water saturation in a porous medium, such as brine-saturated shale, as is common in carbon capture and storage reservoirs, based upon measured electrical conductivity and seismic P-wave velocity. The estimated porosity and water saturation may be used for monitoring carbon dioxide leakage from a carbon dioxide reservoir to the overlying cap rock of the region. Measured electrical conductivity and seismic P-wave velocity data are used by the present method to estimate the porosity and water saturation in the cap rock. If a decrease in water saturation in the cap rock is found, this indicates that carbon dioxide may be leaking up from the carbon dioxide reservoir. An alert signal is then generated to indicate that there may be a carbon dioxide leak.

  • Patent number: 9747393
    Abstract: There is provided a method for modelling a hydrocarbon reservoir that includes generating a reservoir model that has a plurality of sub regions. A solution surrogate is obtained for a sub region by searching a database of existing solution surrogates to obtain an approximate solution surrogate based on a comparison of physical, geometrical, or numerical parameters of the sub region with physical, geometrical, or numerical parameters associated with the existing surrogate solutions in the database. If an approximate solution surrogate does not exist in the database, the sub region is simulated using a training simulation to obtain a set of training parameters comprising state variables and boundary conditions of the sub region. A machine learning algorithm is used to obtain a new solution surrogate based on the set of training parameters. The hydrocarbon reservoir can be simulated using the solution surrogate obtained for the at least one sub region.

A mesh of a discrete fracture network generated by defining a set of cells for each fracture and then a mesh of the matrix medium is generated by dividing each cell by an octree technique, wherein a cell is divided into eight cells. The transmissivities between the cells of the fracture mesh, transmissivities between the cells of the matrix medium mesh and transmissivities between cells of the fracture mesh and cells of the matrix medium mesh are then determined. Finally, the cells and the transmissivities are used for generating an image of the fluid reservoir from which the development of the fluid reservoir is optimized.
