Patent number: 9519865Abstract: Various embodiments include apparatus and methods to provide pipe analysis, annulus analysis, or one or more combinations of pipe analysis and annulus analysis with respect to one or more pipes in a wellbore. The analysis can include application of clustering and classification methods with respect to the status and the environment of the one or more pipes in the wellbore. In various embodiments, the clustering and classification can be used in characterizing borehole annular material including cement bond quality evaluation. Additional apparatus, systems, and methods are disclosed.Type: GrantFiled: June 24, 2011Date of Patent: December 13, 2016Assignee: Halliburton Energy Services, Inc.Inventors: John Quirein, Philip Edmund Fox, Jerome Allen Truax, Dingding Chen

Patent number: 8660796Abstract: Processing gamma count rate decay curves using neural networks. At least some of the illustrative embodiments are methods comprising obtaining a gamma count rate decay curve one each for a plurality of gamma detectors of a nuclear logging tool (the gamma count rate decay curves recorded at a particular borehole depth), applying the gamma count rate decay curves to input nodes of a neural network, predicting by the neural network a geophysical parameter of the formation surrounding the borehole, repeating the obtaining, applying and predicting for a plurality of borehole depths, and producing a plot of the geophysical parameter of the formation as a function of borehole depth.Type: GrantFiled: August 26, 2008Date of Patent: February 25, 2014Assignee: Halliburton Energy Services, Inc.Inventors: Larry A. Jacobson, Dingding Chen, John A. Quirein

Patent number: 8374974Abstract: A system and method for selecting a training data set from a set of multidimensional geophysical input data samples for training a model to predict target data. The input data may be data sets produced by a pulsed neutron logging tool at multiple depth points in a cases well. Target data may be responses of an open hole logging tool. The input data is divided into clusters. Actual target data from the training well is linked to the clusters. The linked clusters are analyzed for variance, etc. and fuzzy inference is used to select a portion of each cluster to include in a training set. The reduced set is used to train a model, such as an artificial neural network. The trained model may then be used to produce synthetic open hole logs in response to inputs of cased hole log data.Type: GrantFiled: March 21, 2003Date of Patent: February 12, 2013Assignee: Halliburton Energy Services, Inc.Inventors: Dingding Chen, John A. Quirein, Jacky M. Wiener, Jeffery L. Grable, Syed Hamid, Harry D. Smith, Jr.

Patent number: 7613665Abstract: Methods of creating and using robust neural network ensembles are disclosed. Some embodiments take the form of computer-based methods that comprise receiving a set of available inputs; receiving training data; training at least one neural network for each of at least two different subsets of the set of available inputs; and providing at least two trained neural networks having different subsets of the available inputs as components of a neural network ensemble configured to transform the available inputs into at least one output. The neural network ensemble may be applied as a log synthesis method that comprises: receiving a set of downhole logs; applying a first subset of downhole logs to a first neural network to obtain an estimated log; applying a second, different subset of the downhole logs to a second neural network to obtain an estimated log; and combining the estimated logs to obtain a synthetic log.Type: GrantFiled: June 24, 2005Date of Patent: November 3, 2009Assignee: Halliburton Energy Services, Inc.Inventors: Dingding Chen, John A. Quirein, Harry D. Smith, Jr., Syed Hamid, Jeffery L. Grable
