New Oil Recovery Technique Proved to be Effective

A research group headed by Dr. Wu Feipeng of the Technical Institute of Physics and Chemistry, CAS has developed a novel enhanced oil recovery technique based on the specific study of the geological features, characteristics of oil reserves and extraction course of the oil fields in China.

The principle of the technique is to modulate the water penetrability of the oil fields by using the mechanical elasticity of a series of well controlled micro- and nano-gel of cross-liked polymer gel. The results of both the lab evaluation and filed work proved to be excellent.

This technique has provided more economic and powerful means for the water flooding recovery of oil with high reliability, high efficiency. It is a new way to redesign the oil recovery measures of the old filed in China. It has attracted great attention from quite a few oil field managers and should be extended to a larger application scale within the next few years.


China Accepted as 4 th Member of CHAOS Project

Recently, the Russian, South Korean and Japanese Chief Scientists of the Carbon Hydrade Accumulation of Okhotsk Sea Project (CHAOS) held a workshop in Seoul, South Korea. At the Workshop, China was accepted as the 4 th member of the project. At the invitation of Dr. Kin Young Kmun, South Korean chief scientist of the project, Luan Xiwu, research professor of the Institute of Oceanology, CAS, attended the symposium.

The CHAOS project was started by scientists from Russia, South Korea and Japan, which was a long-term scientific research project sponsored by governments of the three countries. Its main purpose is to conduct survey on natural gas hydrate in the Okhotsk Sea. So far, two cruises, which lasted more than 60 days, have been made in the sea. In the second cruise, sample of thick-layered and continuous natural gas hydrate in the sea deposit has been obtained. This is the first sample of the continuous natural gas hydrate discovered in the sea deposit.
