Abstract

A continuous search for new technologies to produce the remaining oil from low-productive reservoirs is under way in the Samotlorskoye oil, gas and condensate field. Advances in multi-stage fracturing technology allow producing from the low-productivity zone of BV8(0) horizon which was in commingled production with the underlying highly productive BV8(1-3) horizon 10 years ago. Infill horizontal drilling has been started in BV8(0) horizon which in fact means production with an individual well pattern. The inherent water injection system designed for a good-quality BV8(1-3) reservoir requires some optimization to produce from BV8(0).

Ariadne Software has been developed by OOO Tyumen Oil Research Center to make on-line decisions when optimizing the water injection system. The software execution is based on a group of CRMP (Capacitance resistance) models. To test the Ariadne software for the Samotlorskoye field conditions, a pilot test area has been selected and model calculations have been made.

The authors analyze the results of work based on well performance monitoring and identify errors and limitations.

Key words:

Samotlorskoye field, mature fields, water injection optimization, water flooding, CRM model, interference factors, incremental oil production, infrastructural limitations of water injection system
