Abstract: Disclosed is a method and apparatus for determining the erosional characteristics of a mudcake on a wellbore wall. According to various embodiments of the invention, the method includes preparing a mudcake, forming a mudcake assemblage (122) comprising the prepared mudcake, a screen (124), and a filter paper, and submerging and securing the mudcake assemblage (122) in a container (110) filled with a fluid. The fluid includes one of a native fluid, such as fresh water or seawater, and a foreign fluid, such as a cleaning or wahing fluid or a spacer fluid, to the mudcake. The method further includes agitating the fluid for a plurality of time intervals, removing the mudcake assemblage (122) from the container (110) after expiration of each time interval, and drying the mudcake assemblage (122). Further, the method includes weighing the mudcake assemblage (122) to determine an interval weight for each time interval, and determining the erosional characteristics of the mudcake on the wellbore wall by graphically correlating the determined interval weights of the remaining mudcake in the mudcake assemblage (122) as a function of time. An erosion rate of the mudcake is defined by a slope of a tangent of an initial portion of the graphical correlation between the determine interval weights and cumulative time.

Abstract: A classification scheme for classifying sized bridging materials (107), as used in drilling and/or completion fluids, is disclosed. The scheme identifies a durability metric for the sized bridging materials (107). The durability metric is determined by submitting the sized bridging materials to simulated downhole conditions and measuring variations in the particle size distribution of the sized bridging materials. The scheme then identifies a value range having a higher relative strength and a lower relative strength. The sized bridging materials 107 may then be tested according to the durability metric and associated with a relative strength based on the durability metric determined during the test.

Abstract: A method for quality control and quality assurance of sized bridging materials rotates a control sample having a fluid portion and a solids portion of sized bridging materials in a tubular container for a predetermined period of time. The control sample is then analyzed in a laser particle size analyzer to determine a particle size distribution for the control sample. A wet grinding sample having a fluid portion and a solids portion of the sized bridging materials is then rotated in the tubular container with a loose cylinder rod for a predetermined time to simulate borehole conditions. The tubular container and loose cylinder can take the form of a temperature controlled bar miller. The wet grinding sample is then analyzed in the laser particle size analyzer to determine a particle size distribution for the wet grinding sample. The two particle size distributions are used to define a shift factor that represents the relative strength of the sized bridging materials.
