  • Patent number: 8260573
    Abstract: To monitor performance of wells, allocation factors are dynamically calculated for a particular producer well with respect to plural respective well patterns each including at least one corresponding injector well. The allocation factors represent a production characteristic of the particular producer well in the respective well patterns.

  • Patent number: 8255816
    Abstract: An example method of modifying a model of a field includes presenting a representation of field data in a first window and receiving a selection of a portion of the representation of the field data. The method further includes presenting the portion of the representation in a second window, creating a magnified portion, where the representation and the magnified portion are presented concurrently. The method further includes receiving a request to modify the field data presented in the magnified portion, modifying the field data based on the request, and based on the modified field data, updating the magnified portion and the representation to obtain a modified magnified portion and a modified representation, respectively. The method further includes concurrently presenting the modified magnified portion in the second window and the modified representation in the first window.

  • Patent number: 8244471
    Abstract: A system for analyzing an oilfield having at least one wellsite, each at least one wellsite having a wellbore penetrating a subterranean formation for extracting fluid from an underground reservoir therein, that includes a data collection means for obtaining source data having a plurality of data elements of heterogeneous data types, memory for storing the source data, a functional method configured to perform a function on a dataset of a dataset type to obtain a processed dataset, and a client code configured to process the dataset. The client code includes an object instantiation code configured to use a dataset wrapper class to create the dataset with the dataset type from the source data, and a functional method invocation code configured to call the functional method with the dataset.

  • Patent number: 8180578
    Abstract: A method of analyzing phase transitions of fluid in an oilfield operation of an oilfield. The method includes determining phase boundaries of a multi-component multi-phase system based on geophysical parameters associated with the oilfield, predicting an amount of at least one fluid component in a liquid fluid phase of the multi-component multi-phase system by solving a set of flash equations based on phase boundaries, and performing the oilfield operation based on the predicted amount.
