...) method to generate hundreds of RML samples in parallel for uncertainty quantification. We modified the training-data data set updating algorithm using the iteration index for each thread to implement the asynchronous running mode. The sensitivity matrix at the best solution of each optimization thread...

... with anhydrite. Hence, exploration potential exists in some of the graben areas, and this has encouraged recent exploration activities to reveal the true potential of this reservoir. Abstract Matrix acidizing can effectively stimulate carbonate reservoirs, often resulting in skin factors on the order of –3...

...Core samples Cylindrical Indiana Limestone cores with 1-inch in diameter size were used in all experiments. To investigate the permeability effect, three permeability ranges of Indiana Limestone rocks were used to represent carbonate matrix, and the rock properties were listed in Table 2...

... for a production stimulation feasibility study. The reservoir and well information were reviewed, and a reservoir model was built in an advanced matrix stimulation simulator. Core flow tests with 3D wormhole geometry visualization were used to calibrate the simulator's fluid-rock interaction parameters. Various...

... gradient can be directly calculated. It can also be explicitly expressed in the form of Fick's law, called the generalized Fick's law ( Hoteit and Firoozabadi 2009 ; Moortgat and Firoozabadi 2013 ). The MS diffusion formulation ( Tian et al. 2021 ) with a whole matrix of composition-dependent diffusion...

.... The injected fluid is likely to flow through those high permeability channels and bypass the oil in oil-wet matrix. The high negative capillary pressure prevents the injected fluid from invading into the oil-bearing matrix and expelling oil into the high permeability channels. Heterogeneity and oil-wetness...

... Then, by applying Gassmann's fluid substitution equations (model 3, Eq. 3 and 4 ) to the MLHS curves, the effect on velocities of varying fluid saturations (e.g gas versus brine) can be estimated using the matrix and fluid properties: (3) K S a t K s − K S a t...

... plug testing is not possible because of their friability. In this study, nanoindentation was used to measure the mechanical properties (Young's modulus, creep, and anisotropy) in Eagle Ford ash beds, and to determine the contrast with the formation matrix properties. Two separate ash beds of high clay...

... tension also influences oil recovery in tight oil reservoirs ( Jarrel et al., 2002 ; Alfarge et al. 2017 ; Zhang 2016 ). The low permeability in tight oil reservoirs causes the injected gas to preferentially flow through natural and hydraulic fractures, but not through the non-fractured matrix. Residual...

... to identify fracture location in fractured reservoir models using dynamic data. In DPDK models, the matrix-fracture interactions are typically described by non-neighbor connections (NNCs) which make streamline tracing non-trivial. We use a boundary layer method to reconstruct the fluxes and avoid flux...

... Abstract Flowback rate transient analysis (RTA) is a practical tool for characterizing hydraulic fracture (HF) properties. However, the accuracy of the interpreted results from flowback RTA is challenged by the complexity in two-phase flow in the hydraulic fracture and matrix system...
