摘要： The invention relates particularly to methods for characterizing water-in-oil or invert emulsion fluids for use in drilling well bores in hydro-carbon bearing subterranean formations. A fluid stability measurement method is described. The method includes placing a sample of an emulsion in a gap between electrodes, disturbing the sample, measuring the electrical stability of the sample, and establishing a relationship between electrical stability and time since the sample was disturbed.

摘要： A method of determining the electrical stability of a fluid comprises:
placing the fluid in a gap between a reference electrode (205) having a first potential and a second electrode (210) having a second potential;
coupling the reference electrode (205) and the second electrode (210) with an insulating material (220);
intercepting a path on the insulating material (220) between the reference electrode (205) and the second electrode (210) with a guard electrode (230);
increasing a potential difference between the reference electrode (205) and the second electrode (210); and
measuring the amount of current flow between the reference electrode (205) and the second electrode (210).
The fluid may be a water-in-oil or invert emulsion fluid for use in drilling well bores in hydrocarbon bearing subterranean formations

摘要： Methods and systems for characterizing drilling fluids laden with LCM (Lost Circulation Material) and other solid materials are disclosed. A test cell for analyzing a fluid is provided with a first conical inner portion and an axial positioning device positioned along an axis of the test cell. A first conical plug is coupled to the axial positioning device and is movable in and out of the first conical inner portion along the axis of the test cell. A fluid inlet is positioned at a first location on the test cell and a fluid outlet at a second location.

摘要： Treatment fluids that include magnetic surfactants may be useful in various subterranean operations, e.g., particulate placement operations and drilling operations. For example, some methods may include introducing a treatment fluid into a wellbore penetrating a subterranean formation, the treatment fluid including at least a base fluid and a magnetic surfactant, the magnetic surfactant being a cationic surfactant having a magnetically susceptible counterion.
