    摘要: Fluid compositions comprising water, at least one water soluble polymer, degradable particles or nondegradable particles or both, and degradable fibers have utility as temporary lost circulation prevention systems. The compositions may be placed in a borehole such that they contact perforations, formation cracks, fissures, vugs or combinations thereof. The compositions form a plug or filtercake that minimizes flow between the wellbore and the formation. After completion of the well operation, the fibers degrade and the plug or filtercake weakens and may be washed away, thereby reestablishing fluid flow between the wellbore and the formation.

    摘要: A method is given for inducing heterogeneous proppant placement in a hydraulic fracture in a subterranean formation by causing proppant aggregation through a gel phase transition or chemical transformation in the proppant carrier fluid. Proppant aggregation may be induced by causing or allowing syneresis of the polymer gel that viscosifies the fluid; formation of a polyelectrolyte complex from cationic and anionic polymers included in or created in, the fluid; and by increasing the temperature of the fluid above the critical solution temperature of a polymer in the fluid. The proppant carrier fluid may be formulated such that these transformations occur naturally during or after proppant injection, and the transformations may be chemically triggered or delayed.

    摘要: A method for producing minerals and, more specifically, for producing hydrocarbons, by hydraulic fracturing of the rock, can be used for the optimization of formation fracturing crack processing conditions. The method includes splitting a main stream of a propping agent suspension in a fluid at a mixer output into at least two flows having different volume delivery rates, and comingling the at least two flows before delivering to the hydraulic fracturing zone.
