Nowadays, the marine resources especially the development and utilization of offshore oil and gas resources are more and more attention around the world. Currently, offshore oil and gas has become a major source of the world’s oil and gas p...

Liquefied petroleum gas (LPG) anhydrous fracturing technique, with mixture of propane replacing water in fracturing, compresses propane to a gel state, which was then pressed into rock crevices together with the proppant. This technology ha...

Early cellulose fracturing fluid had problems such as hard matching liquid, poor temperature resistance, incomplete gelout, big formation damage. Instant cellulose fracturing fluid consists of 0.4% hydroxyethyl carboxymethyl cellulose(HECM...

Currently, a number of professional data companies, some universities and related oil & gas companies are carrying on research on "big data" application for various fields in petroleum industry, so as to promote the industry overall efficie...

Now a new technology has been employed to reduce drilling cost and overcome well leakage. Put a high solid content and high water loss thick slurry( HWL-HS) into the well leakage, a solid plug is precipitated by dehydration. People would ra...

In the process of development of oil fields, when the reservoir pressure reduces a lot, then you can use water to maintain reservoir pressure. However, the injected water causes not only damage to the environment, but also a serious drain o...

Recently, Baker Hughes presented its ClearStar fracturing fluid system. This product is capable of complete fracturing construction more efficiently either in conventional or unconventional formations. Compared to conventional guargum, its ...

In recent years, with the constantly increased drilling number and deepening of the drilling depth, although the use of new technologies in rotary drilling method greatly improved drilling speed and quality, some of the problems that exist ...

In 1980s and 1990s, even restrained by petroleum engineering technology, some oil companies like Micelle Energy Company still tried to explore in fine-particle formations. At first, oil companies used horizontal wells to explore shale gas a...

At present, the global market scale of EOR technology is about 3 million barrels per day, and the ratio of three main technologies is 4:2:1. SAGD & CSS are still dominating in thermal EOR. Solar Energy EOR has its limits. China has put CO2 ...
