摘要： Reservoir data obtained from a plurality of fluid reservoirs and comprising dependencies of a composition of a fluid produced from a reservoir on time or on a reservoir pressure or both and at least one parameter characterizing a pore space of the reservoir formation are stored in a training database in a memory storage. An analysis of said reservoir data is performed by a cognitive system, wherein said analysis produces relationships between said dependencies of a composition of a fluid produced from a reservoir on time or on a reservoir pressure or both and said parameters characterizing a pore space of the reservoir formation. Then, new dependencies of a composition of a fluid produced from a new reservoir on time or on a reservoir pressure or both are inputted into the cognitive system and at least one parameter characterizing a pore space of the new reservoir formation based on the produced relationships is predicted. The method also includes planning at least one strategy of production or recovery optimization using the predicted parameters characterizing the pore space, and implementing the planned strategies using appropriate well completions, surface and subsurface equipment for fluid production monitoring and control.

摘要： A method for performing a simulation of a field having a subterranean formation is described. The method includes obtaining phase behavior data of subterranean fluids of the field, generating an equation of state (EOS) model of the fluids based on the phase behavior data, generating a Helmholtz free energy model that reproduces predictions of the EOS model over a pre-determined pressure and temperature range, and performing the simulation of the field using the Helmholtz free energy model. The method may further include reducing the EOS model to a reduced EOS model having a reduced number of components to represent the EOS model over a pre-determined pressure and temperature range, generating the Helmholtz free energy model based on the reduced EOS model, and obtaining and using phase behavior data of injection fluids used. A computer system for implementing the method is also described.

摘要： Estimating petrophysical properties of a hydrocarbon reservoir traversed by at least one wellbore comprises obtaining at least one core sample from the wellbore and obtaining a three-dimensional (3D) porous solid image of the core sample. A 3D pore scale model is generated from the 3D porous solid image. A distribution of reservoir fluids in pores of the reservoir is simulated by a microhydrodynamic simulation using the 3D pore scale models of the core samples and at least one petrophysical property of the reservoir by a microscale modeling using the simulated distribution of the reservoir fluids is simulated by fitting the at least one simulated petrophysical property to well logging data at a depth corresponding to a depth of taking the core sample using free parameters. Governing parameters of the 3D pore scale models are extrapolated along a logged part of the wellbore and the at least one other petrophysical property is estimated by simulation.

摘要： A method of saturated formation permeability determination is intended to determine permeability of producing fluid-saturated formations. The method provides location of a logging instrument in the well, the logging instrument consists of an acoustic emitter, at least two acoustic sensors, at least two electric emitters and at least two electric transducers with each acoustic sensor located between an electric sensor and electric emitter. An acoustic pulse is generated for the formation excitation after that using acoustic sensors acoustic response amplitude is measured and using electric transducers the amplitude of the current initiated by the acoustic impact is measured. Then voltage pulse is generated with the same instrument position and using acoustic sensors the amplitude of the acoustic response initiated by the voltage applied is measured. With the same instrument position the formation acoustic excitation with subsequent measurements of the acoustic response amplitude and current amplitude as well as voltage pulse generation with subsequent acoustic response amplitude measurement are repeated at least once again; note that during each repetition acoustic pulse and voltage pulse are generated with increased amplitudes. Permeability of each formation sub-layer located opposite the instrument acoustic sensors at the particular position of the instrument in the well is calculated, hereby the sub-layer thickness is equal to the distance between adjacent acoustic sensors. The instrument is moved down or up the borehole at the distance equal to the distance between adjacent acoustic sensors and the sequence of all the steps above is repeated for each formation sub-layer. Based on the data obtained the formation permeability is determined.
