Abstract: A fracture insert is disclosed including a first cylindrical portion and a second cylindrical portion disposed opposite the first cylindrical portion defining a radial gap therebetween to form an axial flow channel. The axial flow channel provides a flow path for a drilling fluid from a top of the cylindrical portions to a bottom of the cylindrical portions and the radial gap provides a flow path for the drilling fluid from the axial flow channel to a radial terminus of the first cylindrical portion and the second cylindrical portion.

Abstract: Fluid compositions including a base fluid and at least one granular hemicellulose material. The base fluid may be an oleaginous fluid or a non-oleaginous fluid. The granular hemicellulose material may have a cumulative particle size distribution D90 of about 4 mm or less and D10 of about 1 mm or greater, or D90 of 2.5 mm or less and D10 of about 1.5 mm or greater, or even D90 of about 3.8 mm or less, and D10 of about 2.4 mm or greater. The granular hemicellulose materials useful may have an average aspect ratio equal to or less than about 5:1, an average aspect ratio equal to or less than about 2:1, or even an average aspect ratio is about 1:1. The granular hemicellulose materials have hemicellulose in an amount from about 10% to about 50% by weight, cellulose in an amount from about 30% to about 50% by weight, and lignin in an amount from about 5% to about 35% by weight. The granular hemicellulose materials may be added to the base fluid in an amount from about 1 ppb to about 50 ppb, or even from about 4 ppb to about 40 ppb. The fluid compositions may be useful for sealing fractures in a subterranean formation, and reducing fluid loss in a subterranean formation.
