The latest development of foreign low-damage fracturing fluids systems

At present, the water base fracturing fluids with guar and its derivatives such as gelling agents have the problem of damaging formation, so the development and application of lower damage fracturing fluids are necessary. This paper reviews the current general situation of low-damage fracturing fluids systems of four foreign oilfield service corporations: Schlumberger company, Halliburton service company, Baker Hughes company and BJ services company. Their excellent properties of foreign low-damage fracturing fluid such as temperature resistant, low potential damage, varieties available, reservoir adaptability are unique. During which four kinds of fracturing fluids such as clean fracturing fluids, FiberFRAC^* fracturing fluids techonolgy, hydrophobic associating polymer/viscoelastic surfactant complex fracturing fluids and low-molecular weight fracturing fluids are emphasized, and it will be of guiding significance for the stimulation of domestic reservoir with low pressure, and low permeability offshore oil/gas field. From now on, the development trend of domestic fracturing fluids is to exploit the ones with properities of low or zero formation damage, high-temperature resistance, good reservoir adaptability, and environment friendly.
