What is Directional Drilling?
Most wells drilled for water, oil, natural gas, information or other subsurface objectives are vertical wells - drilled straight down into the earth. However, drilling at an angle other than vertical can obtain information, hit targets, and...>
The rheological property of VES self-diverting acid system
VES self-diverting acid diversion acidizing technology is the new way which was developed for large well section and multiple series of strata in the past few years.VES self-diverting acid system is the key to make this technology come true...>
How are synthetic drilling fluids defined?
There are two on-going debates in the Exploration and Production community about synthetic drilling fluids
Reflections on the Development of Oil Fracturing Technology in China (1
There is no uniform standard for classification and nomenclature of fracturing fluids and named according to the type of thickener. It can be divided into plant gum fracturing fluid type, synthetic polymer fracturing fluid, surfactant s fra...>
Ideas on the Fracturing Fluid Technology Development
The development trend of fracturing fluid technology in the future is still in the direction of low damage, low cost, high efficiency and environmental protection. We still need to strengthen the research about the combination of fracturing...>
Mechanism and present situation of CO2 oil displacement
Greenhouse gas CO2 makes the global warming and constitutes a serious threat survival to mankind as well as the development of social and economic.
L.E.A.D- Performance of ultra-low molecular slickwater system
As for the unconventional oil and gas reservoirs with low permeability, high strength rock, low closure stress and natural fracture formation, slickwater fracturing fluid system has better network crack performance than guar gum system and ...>
