A method of maintaining a hydrostatic pressure exerted on a wall of a wellbore in at least a first interval and a second interval of the wellbore, comprising the steps of: creating at least the first interval and second interval of the wellbore by setting at least a top packer, a first isolation packer, and a second isolation packer in the wellbore, and wherein the first interval is located between the top packer and the first isolation packer and the second interval is located between the first and second isolation packers; running and locating a first sand control assembly in the first interval and a second sand control assembly in the second interval; wherein the first sand control assembly comprises a screen, a blank pipe, a first pressure regulator, said first pressure regulator comprising a backflow device that prevents fluid from entering an inner diameter of the screen or of the blank pipe via the first pressure regulator from an outer diameter of the screen or of the blank pipe; wherein the second sand control assembly comprises another screen, another blank pipe, a second pressure regulator, said second pressure regulator comprising a backflow device that prevents fluid from entering an inner diameter of said another screen or of said another blank pipe via the second pressure regulator from an outer diameter of said another screen or of said another blank pipe; wherein the first pressure regulator is attached to the outside of the screen, blank pipe, or a combination thereof of the first sand control assembly; wherein the second pressure regulator is attached to the outside of said another screen, said another blank pipe, or a combination thereof, of the second sand control assembly; pumping a liquid from a wellhead down a workstring through the blank pipes and through the screens of the first and second sand screen assemblies and simultaneously flowing said liquid through the first pressure regulator and through the second pressure regulator; whereby each of the first and second pressure regulators regulates an amount of pressure exerted by the liquid on the wall of the wellbore; and maintaining the amount of pressure for a specific period of time by maintaining liquid communication between the first pressure regulator and the wall of the wellbore and between the second pressure regulator and the wall of the wellbore. creating at least the first interval and second interval of the wellbore by setting at least a top packer, a first isolation packer, and a second isolation packer in the wellbore, and wherein the first interval is located between the top packer and the first isolation packer and the second interval is located between the first and second isolation packers; running and locating a first sand control assembly in the first interval and a second sand control assembly in the second interval; wherein the first sand control assembly comprises a screen, a blank pipe, a first pressure regulator, said first pressure regulator comprising a backflow device that prevents fluid from entering an inner diameter of the screen or of the blank pipe via the first pressure regulator from an outer diameter of the screen or of the blank pipe; wherein the second sand control assembly comprises another screen, another blank pipe, a second pressure regulator, said second pressure regulator comprising a backflow device that prevents fluid from entering an inner diameter of said another screen or of said another blank pipe via the second pressure regulator from an outer diameter of said another screen or of said another blank pipe; wherein the first pressure regulator is attached to the outside of the screen, blank pipe, or a combination thereof of the first sand control assembly; wherein the second pressure regulator is attached to the outside of said another screen, said another blank pipe, or a combination thereof, of the second sand control assembly; pumping a liquid from a wellhead down a workstring through the blank pipes and through the screens of the first and second sand screen assemblies and simultaneously flowing said liquid through the first pressure regulator and through the second pressure regulator; whereby each of the first and second pressure regulators regulates an amount of pressure exerted by the liquid on the wall of the wellbore; and maintaining the amount of pressure for a specific period of time by maintaining liquid communication between the first pressure regulator and the wall of the wellbore and between the second pressure regulator and the wall of the wellbore.
