Wellbore fluids including fluid loss materials comprising a polymer and a bridging material and related methods

A wellbore fluid, comprising:

• an aqueous base fluid;
• a fluid loss material formulated and configured to form a filtercake on surfaces of an earth formation responsive to exposure to a wellbore pressure, the fluid loss material comprising:
• at least one polymer;
• and
• a bridging material comprising a fatty acid salt of at least one of lithium, sodium, potassium, rubidium, cesium, beryllium, magnesium, calcium, strontium, barium, radium, ammonium, quaternary ammonium, boron, aluminum, gallium, indium, carbon, silicon, germanium, tin, lead, nitrogen, phosphorus, arsenic, antimony, bismuth, copper, silver, gold, zinc, cadmium, manganese, technetium, or rhenium, the bridging material comprising an oil-soluble material formulated and configured to dissolve out of the filtercake to form channels in the filtercake, wherein the bridging material is present in the wellbore fluid at a concentration within a range of from about 14.3 kg/m3 to about 200.0 kg/m3, and wherein a particle size of the bridging material is within a range of from about 2 micrometers to about 100 micrometers;
• and
• an additional bridging material comprising hydrophobically-coated particles of at least one of calcium carbonate, zinc carbonate, barium carbonate, a metal oxide, dolomite, colemanite, ulexite, analcite, apatite, bauxite, brucite, gibbsite, hydrotalcite, galena, hematite, magnetite, iron oxides, siderite, or celestite.
