ORGANIC WATER SCAVENGING ADDITIVES FOR USE IN DRILLING FLUIDS

摘要

Methods and compositions for scavenging water in drilling operations involving oil-based or invert emulsion-based drilling muds are provided. In one embodiment, the methods comprise: providing an oil-based or invert emulsion drilling fluid comprising an organic water scavenging additive; using the drilling fluid to drill at least a portion of a well bore penetrating at least a portion of a subterranean formation; and allowing at least a portion of the organic water scavenging additive to interact with water in at least a portion of the well bore to consume at least a portion of the water.
