摘要： Various methods for redirecting a well treatment fluid to targeted zones of a subterranean formation within a reservoir and diverting the fluid away from high permeability or undamaged zones of the formation by temporarily blocking the high permeability zones are provided. A well treatment fluid can be diverted from a high permeability or undamaged zone of a formation within a reservoir having a high bottomhole temperature by introducing into the reservoir a biodegradable polymer that has excellent heat resistance.

摘要： A method of recovering or increasing the recovery of oil and/or gas from an underground formation involving injecting into the formation, preferably in the form of an aqueous solution, at least one mono alkyl ether of polyethylene glycol in which the alkyl group has 3-5 carbons and the polyethylene glycol contains 3-6 ethylene oxy units e.g. butyl ether of triethylene glycol. Especially preferred are mixtures comprising that and at least one mono alkyl ether of mono or di ethylene glycol e.g. a mixture of butyl triglycol ether, butyl tetraglycol ether, butyl pentaglycol ether and butyl diglycol ether. The method of the invention may be applied to well stimulation treatments such as water blocking, sand consolidation, sandstone acidising and methods of increasing the recovery of oil such as tertiary oil recovery.

摘要： The invention relates to the modification of a curable phenolic resin system by the incorporation of alkylphenol, alkoxyphenol, arylphenol or aryloxyphenol. The resulting resin has reduced water soluble leachates which, in turn, improves the break time when the resin is used to coat proppants for treating subterranean formations.

摘要： The flow of well treatment fluids may be diverted from a high permeability zone to a low permeability zone within a fracture network within a subterranean formation by use of a divert system comprising dissolvable diverter particulates and proppant. At least a portion of the high permeability zone is propped open with the proppant of the divert system and at least a portion of the high permeability zone is blocked with the diverter particulates. A fluid is pumped into the formation and into a lower permeability zone farther from the wellbore. The diverter particulates in the high permeability zones may then be dissolved at in-situ reservoir conditions and hydrocarbons produced from the high permeability propped zones of the fracture network. The divert system has particular applicability in the enhancement of production of hydrocarbons from high permeability zones in a fracture network located far field from the wellbore.
