Identifying potential geothermal resources from co-produced fluids using existing data from drilling logs : Williston, North Dakota
… temperatures (BHT), latitude, longitude, total depth of hole (TD) in meters, the identification number, and the amount of water produced in gallons, can be mined from well logs that exist in various data systems. </p><p> Utilizing this data together with a Geographical Information System …

The Bilayer Polymer Light-Emitting Electrochemical Cells
… CP layer allowed the ions to penetrate the total depth of the CP layer and commence uniform doping propagation. Meanwhile, in the thicker CP layer, the ions do not fully penetrate the CP layer which leads to a broadened light-emitting junction formation. The bilayer LECs have faster turn-on …

Non-perennial streamflow & geomorphic patterns in a semi-arid rangeland slated for development
… monitoring, one precipitation event with a total depth of 92-mm and maximum 60-minute intensity of 50-mm per hour triggered streamflow. Additionally, a hydrodynamic model was built in SRH-2D to compare the impacts of predicted flows through a reach of interest. Topographic pre-development …

Quaternary incision history of the Black Canyon of the Gunnison, Colorado
… Gunnison, suggesting 350-400 m of incision 700m total depth in the last 640ka. Assuming steady average rates this indicates that Black Canyon has been carved in the last 1.4 Ma. Ten strath terraces ascend from the North Fork-Gunnison River to 670 m above the modern river. A cosmogenic burial date …

Order Behavior In High Frequency Markets
… impact that fleeting orders have on spread and depth measures of market quality, and how fleeting orders differ from static orders. Attention is also given to the extent that total depth can be decomposed into the two components of fleeting and static depth. The results suggest that static …

Effect of sodium catchments on soluble soil salts, leaf ion concentration, and the yield of fruit in a water harvesting system.
… samples were collected at 20 cm intervals to a total depth of 160 cm. Twelve sites were selected in the CWW, three sites were selected in the STCA and one site chosen Outside Water Harvesting System (OWS). Also, 12 soil samples were collected from the three sites at different depths in CWW. Soil …

Measurement of Dissolved Gas Concentrations in Natural Waters Utilizing an In-Situ, Membrane Inlet, Linear Quadrupole Mass Spectrometer
… monitored on both downcast and upcast over a total depth range of 200 meters. Spectrometer data were acquired at a rate of 4.2 seconds/sample for the duration of the deployment. Mass spectrometer signals diagnostic of reduced species (CH4, H2S,) in the anoxic waters of the inlet below a depth …

Performance of Deep Geothermal Energy Systems
… such as thermal diffusivity of the rock, depth of the main well, number and length of lateral channels. The sustainable lifetime of the system for a target output power of 2 MW has been calculated for deep geothermal systems with drilling depths of 8000 and 10000 meters, and a financial …

The cytology of adrenocortical regeneration in the rat and the effects of x-irradiation
… cent alcohol. The tissues were analyzed for cell depth, cell type and per cent take (Wyman et al, 1954). b. X-irradiation of the adrenal gland in vitro. One hundred and ten animals were adrenalectomized and the left adrenal gland of each was placed in mammalian Ringer's and either held there for …

Extending the reach of drilling: better wellbore trajectory and torque & drag models
… of borehole positions [true vertical depth, northing and easting], [2] calculating truer measures of wellbore tortuosity and geometric torsion that define the shape and the undulation of the borehole, and [3] predicting accurate measurements of drillstring to borehole friction forces …
