For shale gas, shale hydration expansion is easy to collapse. Therefore, horizontal wells are generally used. Because horizontal wells are mostly in the direction of minimum principal stress.

Water-based mud is generally used in shale operations, because shale itself is a brittle mineral that expands when exposed to water, which can easily cause wellbore collapse and affect drilling quality. Although oil-based mud can support shale, it is difficult for oil molecules to enter into the organic and inorganic pores of shale due to the small pores, which are blocked by capillary pressure.

GREEN company specializes in dealing with all kinds of drilling waste, especially Shale gas drilling mud treatment, we have rich experience and advanced technology. In June of this year, our company signed an order with a company in Indonesia, mainly to process the local shale gas drilling fluid. Our professional team provided on-site guidance and successfully completed the compliance. According to the feedback from the relevant person in charge, our equipment is very efficient in use, and its reliability and safety are very good.
