B -- LOGGING SUPPORT AND BOREHOLE INSTRUMENTATION SERVICES SOL F3794 DUE 063098 POC Della Martinez, Subcontract Specialist, MS P22, Los Alamos, NM 87545, TEL: (505) 667-8538; FAX: (505) 667-8593, e-mail: martinez_della@lanl.gov. CATEGORY A. Design, fabrication, and evaluation of special logging tools, downhole drilling instrumentation, and borehole instrumentation packages for rock mass characterization that are not commercially available. Included are data acquisition, processing, and interpretation of telemetry from various instrumentation packages. Of particular importance are all aspects of borehole seismic technology, including logging tools and instrumentation packages used in passive monitoring of reservoir and hydraulic fracture microseismicity, vertical seismic profiling, formation velocity determinations, and 4-D seismic and crosswell seismic applications. Design of lookahead measurement-while-drilling (MWD) packages and instrumentation to support advanced drilling concept research may also be required. Knowledge is required of the state-of-the-art of seismic sensors, including geophones, accelerometers, and hydrophones; analogue-to-digital conversion relevant to wireline telemetry; high temperature electronics; and commercially available data acquisition systems. CATEGORY B. Assistance with the field deployment of Los Alamos logging and instrumentation packages for (i) the purpose of evaluating their performance in applications importance to the petroleum and geothermal industries, and for (ii) support of the research objectives of field experiments involving Los Alamos technologies. Monitoring of the performance and telemetry of instrumentation packages may extend from weeks to months in reservoir production studies. Included is the insertion of logging tools and instrumentation packages into deep high pressure, high temperature wells. CATEGORY C. Provision for diagnostic logs run to determine well and formation conditions at the FHWTF and at remote sites around the United States. Included are well completion logs and logs useful for characterization of fractured reservoirs. (0152)
