The interference test program was planned and conducted from 16 May to 27 June, 1984. The main purpose of the test was to establish whether there is reservoir communication between the Pouri-Pukemai-Tuhua hydrocarbon accumulations. Since this information is essential for production/reservoir engineering studies and field development planning, multiple well test programs of pulse and interference were simulated and designed to achieve the objective. The recorded test data are studied, analyzed and presented in this report. It is hoped that these interpretations will be of use in formulating the best development program for the oil field.
