Abstract

The paper presents a summary of pressure transient test results for Beryozovskaya suite of NK Rosneft’s oil, gas and condensate field. Based on pressure transient test results for Upper-Beryozovskaya subsuite, it contains terrigenous sediments. Lower-Beryozovskaya subsuite contains an opokamorphic reservoir which demonstrates relationship between fracturing and well deliverability and the nature of pressure buildup curves. The obtained pressure buildup curves have been classified and the reasons for such responses have been analyzed. The paper presents the procedure of well testing scheme selection for Beryozovskaya suite based on well potential productivity.

Key words:

low-permeability reservoirs, silica clay, Beryozovskaya suite, pressure transient test, fracturing
