Abstract: A method, apparatus, and program product perform microstructure analysis of a digital image of rock using a trained convolutional neural network model to generate a plurality of rock features. The rock features can represent a pore space in the microstructure of the rock including pores and throats. In many implementations, a statistical process can be applied to the rock features to generate characteristics of the pore space which can be used in classifying the rock.

Abstract: An apparatus for performing a well test operation includes a tubular member having a surge chamber and a valve that can control fluid flow from a well into the surge chamber during the well test operation. The apparatus can also include a flow control device, in addition to the valve, for further controlling fluid flow into the surge chamber from the well. Flow rate and pressure data can be measured during the well test operation and used to estimate reservoir properties. Various other systems, devices, and methods are also disclosed.

Abstract: Methods and apparatus for investigating and predicting slug flow in complex pipes are disclosed. More particularly, the techniques provide a model of multiphase flow in a complex pipeline and its solution acquired using the Jacobian-Free Newton-Krylov (JFNK) method by way of non-limiting example. The fully implicit formulation framework described in this work enables to efficiently solve governing fluid flow equations. The framework can reduce the multiphase flow model in zones or cells of the pipe that exhibit phase disappearance based on the phase state distributions over the cells. The model of multiphase flow can include a model for single-phase cells that is different from a model for multiphase cells, and the proper model can be selected (or switched) as the phase characteristics of the multiphase flow of the cells change over time. A transient two-fluid model can be used to verify and validate the proposed algorithm for conditions of terrain-induced slug flow regime.

Abstract: In an approach for creating a test plan, a computer identifies one or more interactive inputs associated with a system under test. The computer identifies one or more tests associated with the one or more identified interactive inputs. The computer calculates a test inventory based on the identified one or more tests associated with the one or more identified interactive inputs. The computer creates a test plan that includes the identified one or more interactive inputs associated with the system under test, the identified one or more tests associated with the one or more identified interactive inputs, and the calculated test inventory.

Abstract: The invention allows determining a local change of an admixture concentration in a fluid flow at an entrance to a measurement cell. The change of the admixture concentration in time inside the measurement cell is first determined for a fluid containing the admixture, the change of concentration of which in time at the entrance to the measurement cell is known. Then, an impulse response of the cell is found applying the deconvolution method. The change of the admixture concentration inside the measurement cell is then determined for a fluid being studied with an unknown concentration of the admixture at the entrance. The unknown concentration is determined using the impulse response of the measurement cell and the change of the admixture concentration inside the cell.

Abstract: To improve the accuracy of multiphase mixture flow rate measurements, properties of a multiphase mixture are determined under conditions expected inside a pipeline and flow regimes are determined for the expected flow rates. Slug reducing parameters of the pipeline are provided at a pipeline section and a flowmeter is installed at the end of that pipeline section.
