HIGH RESOLUTION BOREHOLE-TO-BOREHOLE SEISMIC TOMOGRAPHY CAN PROVIDE MUCH OF THE INFORMATION NEEDED TO IDENTIFY SUBTLE OIL RESERVOIR HETEROGENEITIES. TO DATE, MUCH OF THE HIGH RESOLUTION CROSS-WELL RESEARCH HAS INVOLVED THE USE OF FLUID-COUPLED PIEZOELECTRIC SEISMIC SOURCES. HOWEVER, IN PRACTICAL COMMERCIAL APPLICATIONS OF FLUID-COUPLED SOURCES, SOME CONSIDERATION MUST BE GIVEN TO DEPLOYING THE SOU ...

HIGH RESOLUTION BOREHOLE-TO-BOREHOLE SEISMIC TOMOGRAPHY CAN PROVIDE MUCH OF THE INFORMATION NEEDED TO IDENTIFY SUBTLE RESERVOIR HETEROGENEITIES THUS ALLOWING STRATEGIES PLACEMENTOF PRODUCTION WELLS. HIGH RESOLUTION SEISMIC TECHNIQUES ARE IDEALLY SUITED TO HARD ROCK APPLICATIONS WHERE FORMATIONVELOCITIES EXCEED 10,000 FEET PER SECOND. HOWEVER, TO DATE,THE ACQUISITION OF HIGH FREQUENCY TOMOGRAPHIC D ...

A FEASIBILITY STUDY WILL BE CONDUCTED OF A SEISMIC SCRAM-PROCESSING SYSTEM IN WHICH P WAVES FROM LARGE EARTHQUAKES ARE DETECTED AND ANALYZED IN TIME TO INITIATE A NUCLEAR POWER PLANT CORE SHUTDOWN BEFORE THE ARRIVAL OF LARGE, DAMAGING SHEAR WAVE PHASES. A PROTOTYPE SEISMIC SCRAM-MONITORING SYSTEM WILL BE DESIGNED AND IMPLEMENTED ON A SUN 3/160 ENGINEERING WORKSTATION. IN THE PROPOSED SYSTEM, SEISM ...

PRESSURE MEASUREMENTS DEEP IN GEOTHERMAL WELLBORES PROVIDE SOME OF THE MOST VALUABLE DATA FOR MEASURING THE PRODUCTIVITY OF GEOTHERMAL WELLS AND FOR ASSESSING RESERVOIRCHARACTERISTICS. WELLBORES HAVE VERY HIGH PRESSURE AND VERY LOW PH, BUT, MOST SIGNIFICANTLY, THEY HAVE VERY HIGH TEMPERATURES (UP TO 350 DEGREES CENTIGRADE) THAT PRECLUDE PRESENT PRESSURE MEASURING INSTRUMENTATION FROM OPERATING ADE ...

THE AIM OF THIS PROJECT IS TO DETERMINE THE FEASIBILITY OF AN INSTRUMENT FOR IN-SITU MONITORING OF WATER IN LIQUID NONAQUEOUS SYSTEMS. THE METHOD WILL USE ADVANCED SURFACE MODIFICATION TECHNIQUES, FIBER OPTIC PROBES AND MICROCOMPUTING TOOLS. THE METHOD WILL ADD CHEMICAL SPECIFICITY TO A PHYSICAL MEASUREMENT WHILE STILL PROVIDING FOR CONTINUOUS MONITORING AND CONTROL. FIBER OPTIC METHODS OFFER AN E ...

THE CONTRACTOR SHALL DEVELOP A FUZZY SET METHODOLOGY FOR UNCERTAINTY ANALYSIS IN PROBABILISTIC SEISMIC SAFETY ASSESSMENT OF NUCLEAR POWER PLANTS. FUZZY SET LOGIC WILL BEUSED FOR COLLECTING, QUANTIFYING AND PROPAGATING SUBJECTIVE,ENGINEERING JUDGEMENT USED IN THE UNCERTAINTY ANALYSIS. IN PHASE I, FEASIBILITY OF THE PROPOSED APPROACH WILL BE DEMONSTRATED BY APPLYING IT TO SELECTED PARTS OF A PROBABI ...
