Conference Paper: A Case History of Injection Through 1991 at Dixie Valley, Nevada

Abstract
The Dixie Valley injection system has been operational for 3 1/4 years and disperses injectate into the reservoir through three distinct geological environments. Short term step-rate injection tests underestimated the long term injectivity of some of the injectors requiring additional injectors to be drilled. Liberal use of surface discharge over three years allowed orderly development of an eight-well injection system that provides pressure support for nine production wells but has not yet resulted in any cooling problems. Tracer testing identified a single flow path while long term chloride data have demonstrated injection returns to all production wells within one year. Present percentages of injectate recovered from production wells vary from as low as 18 to 100%. Calculated velocities of injectate through various portions of the reservoir and from minimums of 0.67' to 16.5' per hour.
