READ: Shale gas has a complex composition of minerals. Water easily smells clay minerals. This can hinder normal drilling, result in complicated down hole problems like collapsing wall as well as pollute drilling fluids and impact capacity in later production. Mostly due to this, oil-based mud is required. Shale gas has a complex composition of minerals, extending to such common ones as kaolinites, montmorillonites, illites, as well as quartzs, feldspars, mica calcites, dolomites, iron pyrites, apatites, etc. Water easily smells clay minerals. This can hinder normal drilling, result in complicated down hole problems like collapsing wall as well as pollute drilling fluids and impact capacity in later production.

Oil-based Mud Plays Significant Role in Shale Gas Exploration

发表评论 / Industry Update /

READ: Many unsolved problems in shale gas exploration are mostly attributed to drilling fluids. However, shales proneness to hydration swelling, which leads to a string of complex downhole problems like a collapsing wall, has determined oil-based mud to be applied in shale gas exploration. Many unsolved problems in shale gas exploration are mostly attributed to drilling fluids, so proper match between mud properties and engineering parameters gives birth to safe well drilling. Shale gas is produced by fracking since it mainly exists among cracks. However, shales proneness to hydration swelling, which leads to a string of complex downhole problems like a collapsing wall, has determined oil-based mud to be applied in shale gas exploration. Foreign companies apply a special drilling fluids ca

READ: Oil-based drilling fluids is mainly composed of oil as the continuous phase. KOSUN produces complete set of solids control equipment and drilling fluids solids control system as well as such major products as drilling mud shale shaker, high-efficiency mud cleaner, degasser, decanter centrifuge. Oil-based drilling fluids is mainly composed of oil as the continuous phase. It has found wide application in various drilling platforms with its resistance against elevated temperature and calcium salt corrosion, strong sidewall stabilization, good lubricating effects and little damage of oil gas formation. Water, as an unuseful composition, does not account for more than 10% in oil-based drilling fluids. However, it normally takes up 10%~60% in water-in-oil drilling fluids, as an essential p
