Abstract: The disclosure is related to methods of drilling two wells, wherein the two wells are drilled such that the toe of the lateral portion of one well is in proximity to the heel of the lateral portion of the other well. Production from the wells can be improved by a process wherein the formation about the wells is first fractured at the toe of each lateral portion, then fractured along the middle section of each lateral portion, and, lastly, at the heel section of each lateral portion of the wells.

Abstract: Disclosed are compositions and methods for the pressure protection of existing wells during infill drilling operations. The methods can include injecting an aqueous pressure protection composition into an unconventional subterranean formation via an existing wellbore in fluid communication with a rock matrix of the unconventional subterranean formation prior to and/or during injection of a fracturing fluid into the unconventional subterranean formation via a new wellbore in fluid communication with the rock matrix of the unconventional subterranean formation; and producing a hydrocarbon from the existing wellbore during and/or after the injection of the fracturing fluid into the unconventional subterranean formation via the new wellbore.

Abstract: Disclosed are compositions and methods for the pressure protection of existing wells during infill drilling operations. The methods can include injecting a foamed pressure protection composition into the existing wellbore in fluid communication with an unconventional subterranean formation prior to and/or during fracturing of the new wellbore in fluid communication with the unconventional subterranean formation.
