Paper presented at the SPE Reservoir Simulation Conference, February 20–22, 2017
Paper Number: SPE-182713-MS
... propose to control the Newton step length by limiting the estimated local discretization error. The control strategy is conservative far from the solution, and can be shown to result in the standard Newton method otherwise. Computational results are presented for a series of simulation problems...

Paper presented at the SPE Reservoir Simulation Conference, February 20–22, 2017
Paper Number: SPE-182601-MS
... Abstract In this paper, we formulate an adaptive time-stepping strategy in a control system framework for efficient reservoir simulation. Current simulators achieve a trade-off between stability and computational effort by means of heuristically-based time-stepping strategies during...

Paper Number: SPE-163594-MS
... to create a steam trap control effect. It was reported that the use of these restrictive liners allowed the toe-landed tubing strings to be pulled out so that production only occurred from the heel-landed string, and yet production uniformity was preserved. Additionally, a low subcool was achieved over most...

Paper presented at the SPE Reservoir Simulation Symposium, February 2–4, 2009
Paper Number: SPE-118969-MS
... The generic nature of the controller allows a flexible system with which the list of observables ( y ) and controllables ( u ) above may be combined in order to evaluate many different control scenarios. There are two main practical use cases for the ability to set up such control scenarios...

Paper presented at the SPE Reservoir Simulation Symposium, February 2–4, 2009
Paper Number: SPE-118850-MS
.... The proposed solution enables the combination of models with different fluid descriptions (black oil and/or compositional); the conversion into one set of components (the super-set of components) is performed by the delumping capabilities of the controller ( Ghorayeb et al. , 2003 ). This paper...

... and network coupling controller having all the above features. The controller communicates with a selection of reservoir simulators and surface network simulators via an open message-passing interface. It manages the balancing of the reservoirs and surface networks, and synchronizes their advancement through...
