A finite-volume (FV) technique is introduced to model directional resistivity logging sensors that employ tilted-coil antennas in 3-D anisotropic earth formations. The algorithm is based on a coupled scalar-vector potential formulation on a 3-D cylindrical staggered grid. The choice of discretization enforces the correct continuity equations across material boundaries, avoids spurious modes, and leads to a better conditioned system matrix. ...

  • Present and Future Needs in High Temperature Electronics for the Well Logging Industry

  • A Summary of HighTemperature Electronics Research and Development

    Current and future needs in automotive, aircraft, space, military, and well logging industries require operation of electronicsat higher temperaturesthan today's accepted limit of 395 K. Without the availability of high-temperature electronics, many systems must operate under derated conditions or must accept severe mass penalties required by coolant systems to maintain electronic temperatures below critical levels. This paper presents ongoing research and development in the electronics community to bring high-temperature electronics to commercial realization. Much of this work was recently reviewed at the FIRST International High-Temperature Electronics Conference held 16-20 June 1991 in Albuquerque, New Mexico.

  • An Overview of HighTemperature Electronic Device Technologies and Potential Applications

    High-temperature electronics applications are found in combustion systems, well logging, industrial processes, air stagnation points in supersonic aircraft, vehicle brakes, nuclear reactors, and dense electronic packages. We summarize physical effects and materials issues important for reliable operation of semiconductor device technologies at high temperatures (>125¿¿C). We review the high-temperature potential of Si, GaAs, other III-V compounds, and SiC. For completeness, we also comment on nitrides, diamond, and vacuum microelectronics. We conclude that Si on insulator (SOI) technology can be developd readily for small signal operation up to about 300¿¿C. There is some ongoing work in this area. GaAs offers little advantage over Si because of poor device isolation and the lack of reliable contacts above 250¿¿C. Other III-V compounds could be developed for operation to ?>600¿¿C, using processes similar to those used for optoelectronics. There may be a market niche for III-V power devices above 200¿¿C. There is considerable activity in semiconducting SiC, and device functionality has been demonstrated above 600¿¿C. SiC is promising for operation above 300¿¿C, and for power devices at frequencies from de to ?>10 GHz, but it faces numerous challenges to achieve manufacturable status. We attempt to match technologies with application areas.

  • Hybrid Microcircuitry for 300 Operation

    Microelectronic instrumentation for geothermal well logging must operate in ambient temperatures up to 300¿¿C for several hundred hours. This study involved an extensive survey of 25 to 300¿¿C operation of resistors, capacitors, conductors, interconnections, and active devices. Three major selection criteria were: 1) part lifetime of at least 1000 h at 300¿¿C; 2) minimum change in electrical parameters from 25 to 300¿¿C; 3) availability to the common circuit builder (no one of a kind). Certain thick film resistors, capacitors, and conductors were found compatible with such high-temperature operation. In addition, reconstituted mica and aluminum solid electrolytic capacitors were found useful up to 300¿¿C. Simple circuits for a geothermal temperature logging tool have been fabricated using these hybrid materials, components, and Si MOS and JFET devices. Oven tests show satisfactory stability from 25 to 300¿¿C and at least 100-h circuit operation at 300¿¿C.

  • Scaling CMOS Design Rules for HighTemperature Latchup Immunity

    Existing and emerging needs in the automotive, aircraft, space, and well- logging industries call for operation of electronics at higher temperatures than the traditional 125¿¿C. Temperature requirements for many of these applications, however, do not exceed 250¿¿C. Extending the operation of low- cost junction-isolated CMOS to this temperature is feasible through straightforward changes in process technology, circuit styles, and layout design rules. The greatest challenge in using bulk CMOS at high temperature is latchup, which can be triggered by junction leakage. This article presents an empirical model for the holding voltage of CMOS latchup, which can be used to scale the design rules in a way that maintains latchup robustness at higher temperatures.

  • A 55C to +200C 12bit AnalogtoDigital Converter

    This paper describes the design of a 12-bit successive-approximation hybrid analog-to-digital (A/D) converter that is specified to operate over a temperature range of - 55¿¿C to +200¿¿C. This is an important development, especially for the oil well logging industry, since it is now possible to digitize the signal output from a transducer while it is downhole and thereby make the transmitted digital signal less susceptible to noise and interference. Details of the design and construction of the device as well as 1000-h life test data are presented.

  • Service Company Needs

    This presentation considers the high temperature electronics and instrumentation needs of a logging service company. The following topics are addressed: 1) The Well-Logging Function 2) Evolution of the Techniques 3) Problems Due to Market Size 4) Identification of the Key Technologies 5) CMOS and Dielectric Isolation - A Review 6) Passive Components 7) Future Requirements

  • A ZeroInsertionForce Hybrid Circuit Connector for Severe Environments

    A new packaging technology has been developed for complex electronic circuits used in the high-temperature high-vibration environment of oil-well logging instrumentation. Specifically, the design and testing of a 72-pin connector that operates with large area ceramic substrates carryiDg leadless chip- carrier (LCC) devices and other thick film components is considered. The emphasis is on achieving high mechanical and electrical integrity during exposure to severe stress, while allowing easy field replacement of defective hybrid circuits without the need for any special tools to opente the release mechanism. A combination of mechanical shock (100 g levels) aDd vibration (10 g) with an extreme operating temperature range ( - 55 to +200¿¿ C) requires care in the choice of materials and the solution of some special design problems.

  • Fabrication of Passive Components for HighTemperature Instrumentation

    Thin-film resistors and capacitors have been fabricated for use in geothermal well-logging tools. The resistors can operate from 25¿¿C-500¿¿C with a temperature coefficient below 100 ppm/¿¿C; capacitors can operate from 25¿¿C-350¿¿C with a similar temperature coefficient. Chemical vapor deposition (CVD) is used to fabricate both resistors and capacitors. The processing is compatible with most microcircuit processes; and resistors, capacitors, interconnecting metallization, and passivation are all produced by CVD and can be integrated on a single substrate. Resistor material is tungsten-silicon, capacitor electrodes and metallization are tungsten, and dielectric material is silicon nitride. Photolithography is used to delineate component geometry.

  • Hybrid A/D Converter for 200C Operation

    This paper describes the design and development of a high performance hybrid 12 bit analog to digital converter, which will operate reliably at 200¿¿C. A product of this type was found to be necessary in areas such as geothermal probing, oil-well logging, jet engine and nuclear reactor monitoring, and other appl ications where the environments may reach temperatures of up to 200¿¿C. This product represents an advancement in electronics as it proved the operation of integrated circuits at high temperature, as well as providing information about both the electrical and mechanical re1 iabil ity of hybrid circuits at 200¿¿C. Because the circuit design of the A/D converter involved both digital and linear circuitry, this produced an opportunity to evaluate the performance of both technologies at 200¿¿C. Initial mechanical failure modes led to researching more reliable methods of wire bonding and die attachment. The result of this work was a 12 bit A/D converter which will operate at 200¿¿C with .05% linearity, 1% accuracy, 350 ?>Sec conversion time, and only 455mW power consumption. This product also necessitated the development oof a unique three metal system in which aluminum wire bonding is done utilizing aluminum bonding pads, gold wire bonding to all gold areas, and employment of a nickel interface between gold and aluminum connections. This sytem totally eliminates the formation of intermetallics at the bonding interface which can lead to bond failure.
