Geochemical Data from Produced Water Contamination Investigations: Osage-Skiatook Petroleum Environmental Research (OSPER) Sites, Osage County, Oklahoma

The USGS reports chemical and isotopic analyses of 345 water samples collected
from the Osage-Skiatook Petroleum Environmental Research (OSPER) project. Water
samples were collected as part of an ongoing multi-year USGS investigation to
study the transport, fate, natural attenuation, and ecosystem impacts of
inorganic salts and organic compounds present in produced water releases at two
oil and gas production sites from an aging petroleum field located in Osage
County, in northeast Oklahoma. The water samples were collected primarily from
monitoring wells and surface waters at the two research sites, OSPER A (legacy
site) and OSPER B (active site), during the period March, 2001 to February,
2005. The data include produced water samples taken from seven active oil
wells, one coal-bed methane well and two domestic groundwater wells in the
vicinity of the OSPER sites.

美国地质调查局（United States Geological Survey, USGS）发布了从奥塞奇-斯基图克石油环境研究（Osage-Skiatook Petroleum Environmental Research, OSPER）项目中采集的345份水样的化学与同位素分析数据。本次水样采集是美国地质调查局多年持续调查工作的组成部分，旨在研究位于俄克拉荷马州东北部奥塞奇县的一处老化油田内两个油气生产站点的采出水排放物中所含无机盐与有机化合物的运移、归趋、自然衰减及生态系统影响。2001年3月至2005年2月期间，研究人员主要从两个研究站点——OSPER A（遗留站点）与OSPER B（活跃站点）的监测井及地表水体中采集水样。本次数据集涵盖的样本还包括OSPER站点周边7口活跃油井、1口煤层气井以及2口民用地下水井的采出水样本。[由美国地质调查局提供摘要]
