In Situ Steam Fracture Experiments.

Abstract

A downhole steam-generation system has been developed in order to obtain in situ steam fracture propagation data for use in validating the predictive capability of the Los Alamos National Laboratory KRAK code. This system can produce up to 60 moles/second of steam at temperatures (1000 deg C) and pressures (10 MPa) representative of post-shot cavity conditions. Steam flow tests have been performed at S-CUBED in a 3-meter long by 20-centimeter diameter sand column. In addition, steam fracture experiments have been conducted at the Nevada Test Site in both a low-permeability (E.G., microdarcy range) tunnel bed and high-permeability (e.g., darcy range) paintbrush-type tuff. This paper describes the steam-generation system, the steam-flow and steam-fracture test designs, and all test results.
