    摘要: The method for the active or automated control of the reservoir uses a reservoir model with available data such as seismic, log, and core data as inputs, and uses the reservoir model in conjunction with a reservoir simulation tool in order to determine a production strategy which will maximize certain criteria, e.g., profits. The production strategy may include fixed elements which are not easily altered once the wells go into production, and variable elements which can be adjusted without serious effort during production. The production strategy is implemented by drilling wells, etc., and fluids are then controllably produced from the reservoir according to the variable production strategy; i.e., fluid flow rates are monitored by sensors, and, by adjusting control valves, are kept to desired values (which may change over time) set according to the variable production strategy. According to another aspect of the invention, information gleaned as a result of the adjustments to the control means is used to update the reservoir model. As a result, the variable and fixed production strategies can be updated and implemented.

    摘要: A method, apparatus and program product utilize an analytical reservoir simulator to perform inflow simulation for a node during nodal analysis in a multi-well petroleum production system. By doing so, time-lapse nodal analysis may be performed of a transient production system in a multi-well context, often taking into account production history and the transient behavior of a reservoir system. Moreover, in some instances, an interference effect from different wells in a multi-well production system may be considered, and in some instances nodal analysis may be performed simultaneously for multiple wells. Multi-layer nodal analysis may also be performed in some instances to account for the pressure loss in a wellbore between multiple layers.

    摘要: A method is disclosed for building a predictive or forward model adapted for predicting the future evolution of a reservoir, comprising: integrating together a plurality of measurements thereby generating an integrated set of deep reading measurements, the integrated set of deep reading measurements being sufficiently deep to be able to probe the reservoir and being self-sufficient in order to enable the building of a reservoir model and its associated parameters; generating a reservoir model and associated parameters in response to the set of deep reading measurements; and receiving, by a reservoir simulator, the reservoir model and, responsive thereto, generating, by the reservoir simulator, the predictive or forward model.
