Project Description
Since water intrusion into a formation can decrease borehole stability, the affinity for water of a shale on a drilling fluid is a major concern. The Hygrometer, or Activity Meter, as it is sometimes called, provides a measurement of relative humidity in a closed space above an emulsified fluid and relates the humidity to the activity of the water. Activity is defined as the chemical potential or the reaction availability of water. Water loss to the formation from an oil-based fluid may be lowered by dissolving salt in the emulsified water, thereby lowering its activity.
