Disclaimer for Provisional Database: The data you have secured from the U.S. Geological Survey (USGS) National Produced Waters Geochemical Database v2.2 are provisional and subject to revision. The data are released on the condition that neither the USGS nor the United States Government may be held liable for any damages resulting from their authorized or unauthorized use. Distribution Liability: Although the data have been processed on computer systems at the USGS, U.S. Department of the Interior, no warranty, expressed or implied, is made by the U.S. Geological Survey regarding the utility of the data on any other system, nor shall the act of distribution constitute any such warranty. No responsibility is assumed by the USGS in the use of these data. Additional Limitations: The information in the USGS National Produced Waters Geochemical Database v2.2 should be used with careful consideration of its limitations. The database is considered sufficiently accurate to provide an indication of tendencies in water composition from geographically and geologically defined areas. It is not appropriate for depiction of modern produced water compositions or examination of trends on small scales. The USGS makes no warranty regarding the accuracy or completeness of information presented in this database. Specific limitations of the database should be considered. Much of the information in the database cannot be independently verified. Methods of collection, sample preservation, analysis, assignment of geologic units and record keeping were not rigorous or standardized. Because of these uncertainties, users are advised to check data for inconsistencies, outliers, and obviously flawed information. Methods of well construction, sample collection and chemical analysis have changed over time. Samples in the database may not be spatially representative and do not necessarily reflect the distribution and relative amount of water produced within a province and among geologic units. No sampling was planned to accurately depict the aggregate water composition of any area whether it be province, state, county or field. The geologic unit nomenclature developed for petroleum production may have changed over time. Water data collected 30 years ago from a province may not resemble water samples from current production. The composition of produced water within a province, field, or even well may change over time as a result of water flooding, recompletion in other intervals, and workovers. Water samples are commonly collected when a well has production problems or during the initial development of a well. Although criteria were applied to remove the obviously contaminated samples, the culling of unrepresentative data is considered incomplete. Most of the obvious redundant entries were removed from this database. Many of the remaining records represent multiple samples of the same well. Therefore aggregate statistics may be weighted by relatively few wells. |
