    Abstract: High solids content slurry, systems and methods. The slurry comprises a carrier fluid and a solids mixture of first, second, third and fourth particle size distribution (PSD) modes wherein the first PSD mode is at least three times larger than the second PSD mode, which is larger than the third PSD mode, which is larger than the fourth PSD mode, and wherein at least one of the second and third PSD modes is less than 3 times larger than the respective third or fourth PSD mode. The method comprises forming the slurry, positioning a screen in a wellbore and circulating the slurry through the wellbore such that the solids mixture is deposited between the screen and the wellbore. The system comprises a pump to circulate the slurry, a workstring to position the screen and means for converting the slurry to a gravel pack.

    Abstract: Wellbore fluid compositions may include an oleaginous base fluid; and a polymeric rheology modifier incorporating a polar comonomer at a percent by weight (wt %) in the range of 1 wt % to 20 wt %; wherein the low shear rate viscosity (LSRV) of the wellbore fluid measured by FANN 35 rheometer at 3 rpm and 150° F. is in the range of 8 to 12. Methods may include emplacing a wellbore fluid in a wellbore, wherein the wellbore fluid comprises an oleaginous base fluid and a polymeric rheology modifier incorporating a polar comonomer at a percent by weight (wt %) in the range of 1 wt % to 50 wt %; wherein the low shear rate viscosity (LSRV) of the wellbore fluid is in the range of 8 to 12.

    Abstract: A system includes a first fluid comprising a viscosified fluid composed to generate an initial fracture geometry, a first spacer fluid, a second fluid being a high solids content fluid (HSCF) having a fine particle formulation, a third fluid being an HSCF having a coarse particle formulation, a second spacer fluid, a conventional proppant slurry fluid, and a flush fluid. The system includes a positive displacement pump fluidly coupled to a wellbore, the wellbore intersecting a formation of interest, and a controller that executes functions to perform complex fracture generation in the formation of interest. The controller provides pump commands to deliver a number of stage groupings to the formation of interest, each stage grouping including the first fluid, the first spacer fluid, the second fluid, the third fluid, and the second spacer fluid.
