A 363 foot wide x 19 foot deep x 0.25 inch aperture spillway barrier net fabricated of Dynema was installed in Highline Lake in August 1999 to control escapement of juvenile and adult nonnative fish. The net’s placement met the screening requirement in the Procedures for Stocking Nonnative Fish Species in the Upper Colorado River Basin and allowed the stocking of bluegill and largemouth bass in...

one of the mostly used enhanced oil recovery methods is the injection of water or gas under pressure to maintain or reverse the declining pressure in a reservoir. several parameters should be optimized in a fluid injection process. the usual optimizing methods evaluate several scenarios to find the best solution. since it is required to run the reservoir simulator hundreds of times, the process...

detection of oil-water contacts (owcs) is one of the primary tasks before evaluation of reservoir’s hydrocarbon in place, determining net pay zones and suitable depths for perforation operation. this paper introduces bayesian decision making tool as an effective technique in owc detecting using wire line logs. to compare strengths of the suggested method in detecting owc with conventional one, ...

Graham, J.L., J.R. Jones, S.B. Jones and T.E. Clevenger. 2006. Spatial and temporal dynamics of microcystin in a Missouri reservoir. Lake and Reserv. Manage. 22(1):59-68. Environmental factors associated with spatiotemporal variation of microcystin (MC) in Mozingo Lake, a Missouri reservoir, were studied during summer 2001, and annual MC trends were characterized from May 2001-May 2002. MC incr...

Production strategy from a hydrocarbon reservoir plays an important role in optimal field development in the sense of maximizing oil recovery and economic profits. To this end, self-adapting optimization algorithms are necessary due to the great number of variables and the excessive time required for exhaustive simulation runs. Thus, this paper utilizes genetic algorithm (GA), and the objective...

Estimation of net-to-gross (N/G) on a field wide scale was accomplished by integrating rock property trends and high quality 3D seismic data. Edited and anisotropy-corrected sonic logs from deepwater Gulf of Mexico (GoM) were used in combination with core velocity measurements and Biot-Gassmann modeling to determine shale and oil sand trends in low-frequency Vp-Vs space. These trends equally ap...

Quantum states can be stabilized in the presence of intrinsic and environmental losses by either applying an active feedback condition on an ancillary system or through reservoir engineering. Reservoir engineering maintains a desired quantum state through a combination of drives and designed entropy evacuation. We propose and implement a quantum-reservoir engineering protocol that stabilizes Fo...

Reduction of suspended sediment (SS), total phosphorus (TP), and total nitrogen is an important focus for Chesapeake Bay watershed management. The Susquehanna River, the bay's largest tributary, has drawn attention because SS loads from behind Conowingo Dam (near the river's mouth) have been rising dramatically. To better understand these changes, we evaluated histories of concentration and loa...

We consider a system model of a general finite–state machine (ratchet) that simultaneously interacts with three kinds of reservoirs: a heat reservoir, a work reservoir, and an information reservoir, the latter being taken to be a running digital tape whose symbols interact sequentially with the machine. As has been shown in earlier work, this finite–state machine can act as a demon (with memory...
