Abstract:
1. An intervention method of treating a subterranean formation penetrated by a wellbore, the method comprising: providing a carrier fluid stream; providing at least one additive fluid stream; providing at least one solid material stream; preparing a single treatment fluid at a surface location based upon an initial model of fluid properties for the single treatment fluid, the single treatment fluid comprising the carrier fluid stream, the additive fluid stream and the solid material stream; introducing the single treatment fluid by a single treatment fluid stream into the wellbore in a substantially continuous process during a duration of a well intervention operation; monitoring a fluid property of at least one of the carrier fluid stream, the additive fluid stream, the solid material stream and the single treatment fluid stream, while forming the single treatment fluid, wherein the fluid property is monitored before the treatment fluid reaches the subterranean formation; providing at least one monitored fluid property of the carrier fluid stream, the additive fluid stream, the solid material stream and the single treatment fluid stream; updating the model based upon the at least one monitored fluid property during the substantially continuous process; and adjusting at least one of the carrier fluid stream, the additive fluid stream, the solid material stream and the single treatment fluid stream, based upon the updated model to form an adjusted treatment fluid stream, contacting the adjusted treatment fluid stream with the subterranean formation; wherein the monitored fluid property comprises at least one property selected from the group consisting of pH, temperature, simple shear viscosity, complex viscosity, loss modulus, complex modulus, elastic modulus, loss tangent, tan δ, fluid density, chemical composition, addition rate, additive concentration, degree of crosslinking, additive molecular weight, onset temperature for crosslinking, fluid thermal thinning, proppant settling velocity, pressure, UV, IR, NIR, and Raman spectroscopic measurements, and wherein the single treatment fluid is selected from the group consisting of a hydraulic fracturing fluid, an acid fracturing fluid, an acid diverting fluid, a matrix acidizing fluid, a sandstone acidizing fluid, a sand control treatment fluid, a wellbore consolidation treatment fluid, a cementing treatment fluid, a water control treatment fluid, a remediation treatment fluid, a polymer fracturing fluid, a crosslinked polymer fracturing fluid, a foamed fracturing fluids, an emulsion fracturing fluid, a slick water fracturing fluid, a bull heading acid formulation, an organic clay acid treatment fluid, a sand consolidation treatment fluid, and a diversion treatment fluid.
