UNDERSTANDING THE PERFORMANCE OF A LOW-PERMEABILITY GAS-RESERVOIR - HYDE FIELD, SOUTHERN NORTH-SEA

Hyde is a small, low-permeability gas field in the U.K. southern North Sea, which has been developed using horizontal wells. Shortly after p roduction startup in Sept. 1993, the field performance began to give c ause for concern. Both wells were producing formation water, and the g as deliverabilities were lower than predicted. This paper described ho w field data were collected, analyzed, and used in a full-field simula tion model to diagnose the cause of the poor performance and to plan t he future development of the field.
