METHODS AND COMPOSITIONS FOR TREATING SUBTERRANEAN FORMATIONS WITH INTERLOCKING LOST CIRCULATION MATERIALS

摘要

The present invention provides for methods of treating a fluid loss zone in a wellbore in a subterranean formation including providing interlocking notched particulates having an outer face comprising at least one notch therethrough; wherein the at least one notch has a shape and an inner perimeter value; providing interlocking protruding particulates having an outer perimeter portion that protrudes in an approximate equivalent to the shape and value of the inner perimeter of the at least one notch; introducing the interlocking protruding particulates and the interlocking notched particulates into the wellbore in the subterranean formation; interlocking the interlocking protruding particulates and the interlocking notched particulates through the at least one notch to form an interlocking network of at least one interlocking protruding particulate and at least one interlocking notched particulate; sealing at least a portion of the fluid loss zone.

1. A method of treating a fluid loss zone in a wellbore in a subterranean formation comprising:
providing interlocking notched particulates having an outer face comprising at least one notch therethrough;
wherein the at least one notch has a shape and an inner perimeter value; providing interlocking protruding particulates having an outer perimeter portion that protrudes in an approximate equivalent to the shape and value of the inner perimeter of the at least one notch; introducing the interlocking protruding particulates and the interlocking notched particulates into the wellbore in the subterranean formation; interlocking the interlocking protruding particulates and the interlocking notched particulates through the at least one notch to form an interlocking network of at least one interlocking protruding particulate and at least one interlocking notched particulate; sealing at least a portion of the fluid loss zone.
