Thermal neutron capture logs obtained during a log-inject-log operation and utilized in the determination of the water saturation condition of a formation traversed by a borehole are corrected for neutron diffusion and borehole effects by a normalization factor relating the apparent and measured macroscopic absorption cross sections of the rock matrix in the formation.

A system for extending the operational life of the reinjection system of a geothermal power plant energized by high temperature, high silica content geothermal brine from a source such as the Salton Sea geothermal field or the Brawley geothermal field. The stream of geothermal brine which flows through the plant is passed slowly through a zone of particulate material having a large cumulative surface area in contact with the brine to seed the precipitation of dissolved silica from the brine onto the particles so as to reduce the amount of dissolved silica available for precipitation in the reinjection system. The zone of particulate material may be established as a floating silica sludge blanket in a reactor clarifier which also has a reaction zone in which silica precipitation is initiated. The vessel such as a reactor clarifier in which the zone of particulate material is established is maintained devoid of atmospheric oxygen to minimize other chemical reactions in said zone that would be injurious to the reinjection system.
4429221 METHOD FOR DETERMINING FLUID SATURATION CHARACTERISTICS OF SUBSURFACE FORMATIONS Linus S Allen assigned to Mobil Oil Corporation
A system for reducing silica scaling i_n a geothermal power plant energized by high temperature, high silica content geothermal brine from a source such as the Salton Sea geothermal field or the Brawley geothermal field. Particulate material capable of seeding silica precipitation thereon is injected into one or more zones in heat extraction equipment such as steam separators where substantial temperature drops occur, so as to seed the precipitation of dissolved silica from the brine in suspended, particulate form rather than as scaling in the heat extraction equipment. The silica precipitation seeding may be accomplished in flash crystallizer type steam separators, and the particulate seed material may be silica particles recovered from a reactor clarifier downstream of the heat extraction equipment.
