SUBJECT: “Machine Learning for Engineers: Case Histories in Finding Hydrocarbons“
Multi-attribute machine learning using SOM (which is an unsupervised learning process) can be shown to reveal details in the data not previously identified and which can be interpreted to be lithologic in nature. The detail comes with the statistical analysis of the data based on information from each sample at each trace in the data. The result of this sample-based statistical analysis is that one can interpret thin-bed resolution well below conventional wavelet tuning. This in turn, helps with highly accurate reservoir prediction when one ties the information to existing production or in the estimation of new reserves in exploration plays.
This presentation will have examples showing how to accurately calculate known reserves from a reservoir and estimated reserves in an exploratory project. There will also be an example of visualizing depletion as well as case histories in finding hydrocarbons in both carbonates and clastic deposition. Areas covered will be unconventional reserves in the Meramec of central Oklahoma, Upper Wilcox in Duval County, Texas, Austin Chalk, Gonzalez County, Texas, Edwards Reef, Central Texas, Frio in Brazoria County and Penn Reef, Dawson County, Texas.
