Oil and gas exploration is the key technology for the oil and gas industry, . in In the development of the oil industry, oil and gas exploration technology is constantly improvingbeing improved. Oil and gas exploration technologies include ...

Steam-assisted gravity drainage (SAGD) is a successful commercial recovery method to produce heavy oil and bitumen. In this method, a pair of horizontal wells is used as injection well and production well, by using the gravity as the drivin...

From the perspective of oil field development, with the oilfield development in high maturity stage, the water and oil distribution in the underground has tremendous change, the main object of exploitation turns to high dispersed and local ...

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 ...
