Abstract: Well log data is assigned depositional labels by a soft computing method. A model is trained on an expert-interpreted well log by segmenting, assigning fuzzy symbols to the segments, and calculating attribute values for units labeled by the expert. From these values, classifiers are trained for each of a number of depositional types. Finally, a model is developed for translating fuzzy symbols into depositional labels. Once trained, the model is applied to well log data.

Abstract: The present invention incorporates the use of geophysical, geological and formation evaluation data to develop synthetic stratigraphic columns based on depositional rules and sedimentary stacking patterns. The present invention utilizes dynamic assignment and matching whereby the synthetic columns can be easily conformed throughout the reservation characterization process as geological data becomes available.

Abstract: A method utilizing genetic programming to construct history matching and forecasting proxies for reservoir simulators. Acting as surrogates for computer simulators, the genetic programming proxies evaluate a large number of reservoir models and predict future production forecasts for petroleum reservoirs.

Abstract: An adjustable frame member has one end of a first linking member pivotally connected to the adjustable frame member. A first abutting member is pivotally connected to another end of the first linking member and a first side frame member is attached to the first abutting member. A suspension member pivotally connects to the first side frame member and a second side frame member pivotally connects to the suspension member. A second abutting member attaches to the second side frame member and one end of a second linking member pivotally connects to the second abutting member. Another end of the second linking member pivotally connects to the adjustable frame member. A hanger adjustably connects to the adjustable frame member and there is a first adjustment device on the hanger. There is a second and a third adjustment device on the hanger.
