  • Publication number: 20250252383
    Abstract: In some implementations, a system may obtain a first set of data quality rules for an incoming dataset and a second set of data quality rules for an outgoing dataset. The system may perform a first data quality validation check for the incoming dataset based on a comparison of data quality metrics associated with the incoming dataset and the first set of data quality rules, and may process the incoming dataset to generate an outgoing dataset based on the incoming dataset passing the first data quality validation check. The system may perform a second data quality validation check for an outgoing dataset based on a comparison of data quality metrics associated with the outgoing dataset and the second set of data quality rules, and may publish the outgoing dataset to a downstream data sink based on the outgoing dataset passing the second data quality validation check.

  • Patent number: 10866340
    Abstract: A method, apparatus, and program product model an oilfield asset by selecting, for each of multiple sectors of the oilfield asset, a sector model from among a collection of sector models, building a multi-resolution integrated asset model of the oilfield asset using the selected sector model for each of the sectors, and performing a computer simulation using the multi-resolution integrated asset model. The collection of sector models for each sector includes multiple sector models modeled at varying resolutions. In addition, the multi-resolution integrated asset model includes a surface network model that couples the selected sector models to one another. As such, different sectors of an oilfield asset may be modeled at varying resolutions to balance accuracy and turnaround time when performing integrated oilfield asset modeling.

  • Publication number: 20080213483
    Abstract: The invention includes an article for use in preparing a visual presentation having a paper or paper display item with ruled lines pre-printed thereon, and a reducing fluid source. The user can apply the reducing fluid from the reducing fluid source to the ruled lines to chemically reduce the ruled lines on at least a portion of the paper or paper display item to thereby render that portion free of visual ruled lines. Also included is a method of preparing a visual presentation comprising providing a paper or paper display item having ruled lines pre-printed thereon, writing on the paper or paper display using the pre-printed lines for guidance, and applying a reducing fluid to the lines to render the ruled lines substantially invisible without rendering invisible the writing disposed on the paper or paper display.

  • Patent number: 6203248
    Abstract: A bottom-founded offshore structure in relatively shallow waters is protected against sliding. It uses at least one pile and a suction pump inside the pile. The pile has a length-to-diameter ratio such as to achieve sufficient pile imbedment with the selected suction pump. A dedicated pile lowering and lifting device lowers and lifts the pile as needed. Guides allow the pile's vertical motion and limit its rotational motion during imbedment and extraction. A stop device limits the vertical motion of the pile's top rim during pile extraction. The pile is reusable, light weight, easy to install and to extract, self-contained, and economical in relationship to its high holding power when imbedded.
