  • Patent number: 11187825
    Abstract: Disclosed herein is a formation evaluation method including estimating a total porosity of an earth formation as a function of bulk density and total nuclear magnetic resonance (NMR) porosity of the earth formation. The total porosity of the earth formation as estimated underrepresents bitumen content. A gas filled porosity of the earth formation is estimated as a function of the bulk density and the total NMR porosity. A kerogen volume of the earth formation is estimated as a function of the gas filled porosity and a total organic carbon content of the earth formation. A bitumen filled total porosity is determined as a function of the estimated kerogen volume and the estimated total porosity of the earth formation. A corrected kerogen volume of the earth formation is determined as a function of the estimated kerogen volume and the estimated total porosity of the earth 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.

  • Patent number: 10309219
    Abstract: In order to determine characteristics of a gas-oil transition zone in a gas capped oil reservoir, samples of a reservoir fluid from a gas and an oil part of the reservoir are taken. To configure an equation of state of hydrocarbon mixtures, reservoir temperature and pressure are measured in places where the samples of the reservoir fluid are taken and densities and compositions of the samples are determined. Porosity, water saturation and total hydrogen content of a saturated rock are measured along the wellbore and a volume and a hydrogen content of hydrocarbon phases are determined. Using the equation of state, density and composition of the hydrocarbon phases are computed and a specific hydrogen content in gas and oil along the wellbore is determined. Gas and oil saturation distribution along the wellbore is determined from the determined specific hydrogen content, determined hydrogen content of the hydrocarbon phases and the measured porosity.

  • Patent number: 10209402
    Abstract: A method, apparatus, and program product utilize a generalized grid cell pinchout operation to remove small cells from a reservoir simulation grid, e.g., prior to running a reservoir simulation. The generalized grid cell pinchout operation may utilize a connectivity matrix representing transmissibilities of one or more “pinch” cells to be removed as well as that of “background” cells that neighbor the pinch cells. Removal of the pinch cells includes determining a Schur complement of the connectivity matrix to generate a reduced connectivity matrix from the connectivity matrix.

  • Patent number: 10180515
    Abstract: In accordance with embodiments of the present disclosure, systems and methods for downsampling DAS data in a way that enables accurate interpretation of acoustic events occurring in the data are provided. 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. This may achieve a higher signal-to-noise ratio in the downsampled data.

The elements include a first element having a boundary defined by the finite element mesh, and at least a portion of the boundary of the first element represents a discontinuity in the subterranean region. A boundary element mesh is generated over the boundary of the first element, and the subterranean region is simulated using the finite element mesh and the boundary element mesh.

  • 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: 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.
