Artificial lift is artificially adding the energy to the bottom of the oil well to maintain a low production pressure, so that the oil can be obtained by the reservoir fluid from the formation. For the late period of the flowing wells or no...

Oilfield wastewater treatment is an important part of oil production process. This article describes the characteristics of oilfield wastewater, and introduced details about the current oilfield wastewater treatment technology and its advan...

When producing the oil and gas from the deep wells, low permeability rock by using high pressure fracturing treatment could split formations. Oil and gas collecting into the crack formation of the channel, it requires fluid injection rocks ...

Oilfield waste water treatment is the key procedure in the oil production process. This article introduce the characteristics of oilfield waste water, detailed describe the current waster water treatment technology and its advantages and di...

Liquefied petroleum gas (LPG) fracturing technology is a new dry fracturing technology developed by the Canadian Gasfrac EnergyServices, first established in 2011 to obtain the annual ‘World Shale Gas Award’ at the World Shale Gas Conferenc...

This paper discusses the cause of emulsifying crude oil, the harm of transporting crude oil emulsion are reviewed in this paper. In order to get the better results before the emulsified crude oil transport, demulsification mechanism was pro...

This article discusses the causes of emulsified crude oil produced, at the same time jeopardize review crude emulsion transfer process, emulsified oil gathering for former better breaking, breaking mechanism is proposed.

In the process of oilfield development, the common method is to inject water into the underground reservoirs, that result in the problems of high water content and low oil production capacity during the oil extraction, thereby affecting the...

With the increase of low-permeability oil and gas reservoir development efforts, fracturing as main production and injection increasing of low-permeability oil and gas reservoir, has aroused more and more concern.

Due to the damage of drilling & completion process to oil and gas layer, oil exploration is confronted with decreased production. In recent years, some progress on reservoir protection has been made in the drilling & completion of oil and g...
