Development planning and reservoir management in the Duri steam flood
The overall objective of reservoir management and development planning for the Duri field is to maximize project value. Key elements of Duri`s reservoir management practices include: injecting steam in new patterns at rates up to about 1.2 BCWEPD/NAF or the maximum rates achievable below fracture pressure; distributing the steam into reservoir layers in proportion to their h{phi}S{sub o}; maintaining these rates until steam breakthrough occurs in multiple wells in a pattern; then performing injector wellwork to shift steam out of the breakthrough layers while continuing initial rates into the non-breakthrough layers. The area-wide rate reduction schedule caused by these shifts resembles a heat balance (Vogel) rate reduction schedule. The steam that is shifted out of an old steamflood development area becomes the supply of steam for the start up of a new area. Key elements of Duri`s development planning practices include: obtaining sufficient reservoir information to be able to predict performance of all areas in the field; dividing the undeveloped parts of the field into steamflood areas that are logical and will fit the steam availability and construction scheduling constraints of the project; ranking the new projects by their profitability; and installing them at a schedule that matches the steam shifts out of the old areas with the ramp up of the new area so that steam plant capacity is fully utilized. This paper discusses the interrelationships between reservoir management practices, development planning, and the maximization of overall DSF project value.
