Abstract Geothermal logging tools are difficult to develop due to sustained high temperature operation. Recent commercial component offerings are significantly altering the high temperature geothermal tool problem. This paper implements a new baseline geothermal tool circuit working with five 225C, SOI components. An example tool including up to four spinners (fluid flow measurement), four analog inputs (for pressure, temperature or other sensors), EEPROM storage (program and data), FSK logic (wireline data transmission), and a high-speed UART (tool communication). Field updates of code and calibration constants are supported. Further, this paper demonstrates how the tool electronics can be expanded for more complex applications such as a geothermal well logging camera.

High Temperature Operation

Owing to the high temperature inside a sulfur recovery unit (SRU) thermal reactor, detailed experimental measurements are difficult. In the author’s previous studies, several methods have been assessed to resolve the abnormality of the SRU thermal reactor under high temperature operation. This paper presents a new easier and more economical method. The effects of inlet air quantity and inlet O2 mole fraction on the combustion and fluid flow in a SRU thermal reactor are investigated numerically. The flow field temperature, S2 recovery, H2S mole fraction, and SO2 emissions are analyzed. This paper provides a guideline for adjusting the inlet air quantity and the inlet O2 mole fraction to reduce the high temperature inside a thermal reactor and to ensure an acceptable sulfur recovery.
