THE U.S. HAS AN ESTIMATED 327 BILLION BARRELS OF OIL IN EXISTING PRODUCTION FIELDS WHICH REMAINS IN PLACE EVEN AFTERPRIMARY AND SECONDARY RECOVERY TECHNIQUES HAVE BEEN EMPLOYED. HIGH RESOLUTION BOREHOLE-TO-BOREHOLE SEISMIC TOMOGRAPHY CAN PROVIDE THE INFORMATION NEEDED TO LOCATE THESE UNPRODUCED REGIONS THROUGH THE IDENTIFICATION OF SUBTLE GEOLOGIC ANOMALIES AND CAN BE USED TO ASSESS THE PROGRESS O ...

180 Ultra-Lightweight Carbon-Carbon Cooling Structure For Pixel and Silicon Strip Detectors-HYTEC, Inc., 110 Eastgate Dr., Suite 100, Los Alamos, NM 87544-3304; (505) 662-0080 Mr. William O. Miller, Principal Investigator Mr. William O. Miller, Business Official DOE Grant No. DE-FG03-97ER82397 Amount: $75,000 Removal of heat from the next generation of particle detection systems used in high ...

IMPROVED ELECTRONICS IN THE PREAMPLIFIER CIRCUIT OF CALORIMETER DETECTORS IS DESIRED TO IMPROVE THE ABILITY TO COLLECT DATA FROM HIGH ENERGY ACCELERATORS FOR PHYSICS EXPERIMENTS. EXTREMELY LOW NOISE AMPLIFICATION IS REQUIRED TO AVOID POOR SIGNAL TO NOISE RATIOS SINCE ANALOG SUMS OF ALL THE DETECTOR SIGNALS ARE PERFORMED FOR TRIGGER PURPOSES. FAST SIGNAL PROCESSING SPEED IMPOSED BY THE EVENT RATES ...

A MAJOR PROBLEM ASSOCIATED WITH THE USE OF ULTRA-HIGH-RESOLUTION GAS CHROMATOGRAPHY FOR EFFLUENT MONITORING IS THE RELATIVELY LOW SPEED OF ANALYSIS. WE PROPOSE TO DEVELOP AN ULTRA-HIGH-SPEED CAPILLARY GAS CHROMATOGRAPH WHICH WOULD BE SUITABLE FOR THE ANALYSIS OF EFFLUENT SAMPLES IN JUST A FEW SECONDS. THE HEART OF THE NEW INSTRUMENT WOULD BE A MICROBORE COLUMN WITH AN INTERNAL DIAMETER OF 50 MUM O ...

40900 November 18, 1996 JP Accelerator Works, Inc. Linear collider accelerator systems, proposed to extend the frontiers of high energy physics research, require thousands of megawatts of peak rf power at microwave frequencies. Existing rf power devices such as klystrons are limited in rf peak power to levels that would require thousands of devices to po ...

IMPROVED MANAGEMENT OF HYDROCARBON RESERVOIRS MAY BE THE MOST IMPORTANT KEY TO MAINTAINING OR EXPANDING THE PETROLEUM/NATURAL GAS PRODUCTION CAPABILITY OF THE U.S. IN THE WORLD MARKET. NEW INTERWELL SEISMIC IMAGING OF THE DISTRIBUTION OF RESERVOIR DESCRIPTION, SIMULATION, AND MANAGEMENT. THIS TECHNOLOGY OFFERS ONE OF THE FEW MEANS AVIALABLE TODAY FOR EVALUATING THE STATE OF THE RESERVOIR BETWEEN S ...

THIS RESEARCH PROJECT WILL DIRECTLY ADDRESS THE PROBLEM OF SWEEP IMPROVEMENT FOR ENHANCED OIL RECOVERY (EOR) PROCESSES. ONE OF THE MAJOR PROBLEMS IN CONDUCTING AN EFFICIENT EOR PROCESS IS THE CONTROL OF THE INJECTED FLUIDS. IN MOST FIELD APPLICATIONS OF MISCIBLE OR IMMISCIBLE SOLVENT DRIVES, SUCH AS CARBON DIOXIDE OR LIGHT HYDROCARBON FLOODS, THE PRESENCE OF RESERVOIR HETEROGENEITIES LEADS TO EARL ...

MOTOR OPERATED GATE VALVE OPERABILITY PROBLEMS AND FAILURES AT NUCLEAR POWER PLANTS ARE A MAJOR SAFETY CONCERN AS STATEDIN NRC IE BULLETIN 85-03 AND GENERIC LETTER 89-10. THIS PROPOSAL IS AIMED AT IMPROVING GATE VALVE PERFORMANCE BY (1) DEVELOPING COMPREHENSIVE PERFORMANCE PREDICTION MODELS FOR USE OVER A RANGE OF OPERATING CONDITIONS, (2) DEFINING LIMITS, BASED ON SPECIFIC DESIGNS, BEYOND WHICH E ...
