SOEKNING AV UNDER YTAN BEFINTLIGA KOLVAETEN MED HJAELP AV HAVSBOTTNENS TEMPERATURGRADIENTER, LAEMPLIGEN GENOM ANVAENDNING AV ETT MULTIPEL TERMISTORMAETHUVUD.

摘要

Disclosed are a method and a system for measuring the sea floor temperature gradient several meters into the formation at each of an array of measurement sites, and using these gradients to explore for and characterize hydrocarbon deposits. The measurements can be taken with a special lance driven into the otherwise undisturbed sea floor.
