  • Publication number: 20180218098
    Abstract: Systems, methods, and computer-readable media for forecasting a time to complete a simulation of a reservoir simulation model. A processor can run a simulation of a reservoir simulation model for a first predetermined period of time associated with a first computation step of the simulation. The processor can measure a performance result of the simulation for the first predetermined period of time. The performance result can include an elapsed wall clock time and a timespan simulated. The processor can then forecast a remaining time to complete the simulation of the reservoir simulation model based on the performance result.

  • Patent number: 9898560
    Abstract: Simulation system and method for a reservoir represented by a model having a plurality of matrix nodes, a plurality of fracture nodes, a fracture zone and a fracture-free zone are described. One embodiment includes computer-implemented steps of, for each of a plurality of matrix nodes in interconnected zones, characterizing the matrix nodes as dual matrix nodes or non-dual matrix nodes. Dual matrix nodes may be treated as a block and eliminated, after which the coefficient matrix and RHS vector for the model are updated. In-fill patterns between and among fracture nodes and non-dual matrix nodes resulting from the elimination are determined. For non-dual matrix nodes, the nodes are merged to a fracture grid, after which the coefficient matrix and RHS vector for the model are updated accordingly. The resultant linear system is linearly solved, and backsolving is performed for any eliminated dual matrix nodes.

  • Publication number: 20150134314
    Abstract: In some embodiments, systems, methods, and articles may operate to compute, in parallel, to determine values of unknowns in network equations associated with a network of sub-surface wells and at least one surface facility, for intra-well subdivisions of the network, and then for inter-well subdivisions of the network, wherein the computing is based on default values of the unknowns, or prior determined values of the unknowns. Additional activities may include constructing a distributed Jacobian matrix having portions comprising coefficients of the unknowns distributed among a number of processors, wherein each of the portions is distributed to a particular one of the processors previously assigned to corresponding ones of the subdivisions. The Jacobian matrix may be factored to provide factors and eliminate some of the unknowns. Back-solving is used to determine remaining unsolved ones of the unknowns, using the factors. Additional apparatus, systems, and methods are described.

  • Patent number: 8461978
    Abstract: A wireless ultrasound probe has a probe case enclosing a transducer array, an acquisition circuit, a transceiver and a battery. The probe also includes a loudspeaker which produces audible sounds as a function of the range between the wireless probe and a host system. When the probe is within a near field range of the host system, the loudspeaker is silent. But if the probe is moved to an intermediate or a far field range from the host system, the loudspeaker sounds an alert. This audible alert can be used to locate the probe by transmitting a paging signal which, upon reception by the probe, causes the probe to sound its alert. If the probe is moved to an unauthorized location where it is within range of a transmitter or receiver, the reception of a signal by the probe, the transmitter, or receiver will sound an alert signaling the unauthorized presence of the wireless probe.
