MONITORING OF STEAM CHAMBER GROWTH

摘要

A methodology and system promote hydrocarbon production from a reservoir using steam assisted gravity drainage. The technique comprises deploying sensors in a subsurface environment containing the reservoir. The sensors are used to obtain data on properties related to a steam assisted gravity drainage region of the reservoir. Based on the data collected from the sensors, the amount of steam injected into areas of the reservoir may be adjusted to facilitate, e.g., optimize, production of hydrocarbons.

1. A method for monitoring steam chamber growth, comprising:
deploying sensors subsurface in a steam assisted gravity drainage region of a reservoir from which hydrocarbons are produced; employing the sensors to measure data on the electrical and elastic properties of the steam assisted gravity drainage region; processing the data to predict a distribution of in situ bitumen, swept bitumen, and transition zone; and tracking growth of a steam chamber by measuring and processing the data over time.
