  • Progress and Practice of Key Cementing Technologies for Deep and Ultra Deep Wells -- Part I
    Deep and ultra deep layers are important replacement areas for increasing oil and gas storage and production. After continuous technological breakthroughs, significant progress has been made in deep and ultra deep well cementing technology,...
  •  Hydraulic Fracturing
    In unconventional fields, hydraulic fracturing is a requirement, not an option. Whether the water used in fracking is recycled produced water or freshwater, it must be treated to remove bacteria to minimize equipment damage. One 100-barrel-...
  • The World Market of Oil
    For most of the Age of Oil, groups of producers have tried to control its price. From the 1920s, that strategy was co-ordinated by the Railroad Commission of Texas, supported by other US states and federal authorities. Then from the 1970s i...
  • Infinite level fracturing technology
    Based on the new type of oil and gas reservoir, a new type of continuous differential casing sliding sleeve is used to determine the sliding sleeve and casing, and then implement conventional cementing, and then implement a series of hydrau...
  • Oil and Gas Exploration and Development Process
    The main process of oil exploration and development is as follows: Geological Survey - Geophysical Exploration - Drilling - logging - Logging - Completion - Cementing - Perforation – oil extraction - workover - increased mining - transporta...
  • Instant non-residue cellulose fracturing fluid
    The traditional cellulose fracturing fluid is very difficult to blend,with poor temperature resistance performance,gel breaking is not completely,serious damage to the stratum,and has many other problems.Instant non-residue cellulose fractu...
  • Overview of Artificial Lift Methods
    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...
  • The Status and Developing Trend of Oilfield Wastewater Treatment Technology
    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...
  • What is petroleum proppant
    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 ...
  • The treatment technology status and development trend of oilfield waste water
    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...
