Method and aqueous fluid using hydrophobically modified guar guns as fluid loss reducers |
摘要 |
A process involving the drilling, conditioning (completion) and intervention (work-over) of a drilling rig, in which the permeability, i.e. filtration losses, through the walls of the well into the geological formation, is controlled by addn. of an amt. of hydrophobically-modified guar gum in an aq. fluid, which is dispersed in the well during operation. Also claimed is the aq. fluid compsn. used in the process.
