Highly accurate survey-grade Global Positioning System (GPS) technology was used at the two Osage-Skiatook petroleum environmental research sites to document the locations of observation wells, geoprobe holes, and other sampling sites of 15 research scientists. Real-time kinematic (RTK) GPS was the method used, because it is stable, fast, and accurate. Initially three survey monuments...

We are involved in a multidisciplinary investigation to study the transport, fate, and natural attenuation of inorganic salts, trace metals, radionuclides and organic compounds present in produced water, and their impacts on soil, surface and ground water and the local ecosystem at the Osage-Skiatook Petroleum Environmental Research (OSPER) A and B sites, located in Osage County, OK...

As a part of a multidisciplinary study of the impact of oil wells and oil production on the environment, we are investigating the hydrology of the OSPER B site, which is located at Skiatook Lake in Osage County, Oklahoma. Salt and crude oil from oil well brine pits and accidental releases from oil tank batteries have contaminated soil, ground water, and surface water at this site...

An active oil production site (Osage-Skiatook petroleum environmental research Site B) in Osage County, Oklahoma is under study to determine the impacts on soils and rock of brine and hydrocarbon spills. The goals of the soil and rock characterization are to 1) document and identify the type, degree, and areal extent of brine and hydrocarbon releases, 2) understand controls on the...

A site characterization study was conducted at an old oil production area where highest activity occurred during the 1930's. Two site locations referred to as OSPER are along the shoreline of Skiatook Lake northwest of Tulsa, Oklahoma. Crude oil and brine water releases have impacted soils, surface and ground water, and the Oak cross-timber ecosystem. Local effects include soil...

Ground electromagnetic and dc resistivity geophysical surveys were used to interpret the subsurface distribution of salinized soil, water, and bedrock at two sites (A and B) and to characterize the larger scale hydrologic setting. Measurements were made on grids of about 1000 square meters using a very shallow penetrating (less than 10 m) electromagnetic (EM) geophysical system (EM31)...

Soils at an active oil production site with a history of surface releases of produced water were investigated to determine the chemical signature of salt contamination and the spatial distribution of soil salinity in relation to areas of obvious salt scarring. Grab samples of shallow soil (0-15 cm) and selected soil profiles to depths of 0.6 to 1.7 m were collected onsite and offsite...

About 15 scientists from the U. S. Geological Survey, other Federal agencies and academia are involved in a multidisciplinary investigation to study the transport, fate, and natural attenuation of inorganic salts, trace metals, radionuclides and organic compounds present in produced water, and their impacts on soil, surface and ground water and the local ecosystem at the Osage-Skiatook...

In February 2001, the USGS started studies of the impacts of produced water and hydrocarbon releases at 2 research sites adjacent to Skiatook Lake in southeastern Osage County near Tulsa, Oklahoma. Both sites are in a dissected area of modest relief underlain by interbedded shale, siltstone, and sandstone. Thicker resistant sandstone units typically form the hill crests. Hillslopes are...
