Environmental conditions affecting the efficiency and efficacy of piscicides for use in nonnative fish eradication
Peter James Brown
2010, Thesis
Conservation of native fish is a pressing issue for fisheries managers. Conservation efforts often require eliminating threats posed by nonnative fish by eradicating them with piscicides. The piscicides rotenone and antimycin are used for eradication but their application is often inefficient or ineffective. My goal was to increase the efficiency...

Predicting S-wave velocities for unconsolidated sediments at low effective pressure
Myung W. Lee
2010, Scientific Investigations Report 2010-5138
Accurate S-wave velocities for shallow sediments are important in performing a reliable elastic inversion for gas hydrate-bearing sediments and in evaluating velocity models for predicting S-wave velocities, but few S-wave velocities are measured at low effective pressure. Predicting S-wave velocities by using conventional methods based on the Biot-Gassmann theory appears...

Reserve growth during financial volatility in a technologically challenging world
Timothy R. Klett, Donald L. Gautier
2010, Open-File Report 2010-1145
Reserve growth (growth-to-known) is the addition of oil and gas quantities to reported proved or proved-plus-probable reserves in discovered fields. The amount of reserve growth fluctuates through time with prevailing economic and technological conditions. Most reserve additions are the result of investment in field operations and in development technology. These...
Applying probabilistic well-performance parameters to assessments of shale-gas resources
Ronald R. Charpentier, Troy Cook
2010, Open-File Report 2010-1151
In assessing continuous oil and gas resources, such as shale gas, it is important to describe not only the ultimately producible volumes, but also the expected well performance. This description is critical to any cost analysis or production scheduling. A probabilistic approach facilitates (1) the inclusion of variability in well...
