Abstract:
Disclosed are systems and methods for producing oil and gas while removing hydrogen sulfide from fluids produced from oil and gas reservoirs and injecting a sour gas stream containing the hydrogen sulfide into an underground formation. Hydrogen sulfide-selective membranes are used to debottleneck known systems and methods by removing hydrogen sulfide from bottlenecked plant process steps including sour gas compression, hydrogen sulfide removal and sour gas injection. Pressure ratio across the membranes can also be manipulated to provide further debottlenecking. Gas-gas eductors are also disclosed for use in leveraging relatively high-pressure streams to boost the pressure of low pressure streams. Oil production is thus increased.

Claim (Index 8):
A method for increasing oil and/or gas production in an integrated oil and gas production plant including hydrogen sulfide removal and sour-gas injection, comprising:\n a. separating a feed stream of produced fluid from a subterranean reservoir into an associated gas stream containing 1-50% hydrogen sulfide by volume, a water stream and an oil stream; b. compressing a first portion of the associated gas stream in an associated gas compressor to form a first compressed associated gas stream; c. passing the first compressed associated gas stream over a hydrogen sulfide-selective membrane to remove hydrogen sulfide from the first portion of the associated gas stream and form a permeate stream enriched in hydrogen sulfide and a retentate stream depleted in hydrogen sulfide and enriched in hydrocarbon gases; wherein the hydrogen sulfide-selective membrane is upstream or downstream of the associated gas compressor; d. feeding a feed gas stream comprising the retentate stream and a gas stream separated from the oil stream to a first gas processing plant; wherein the feed gas stream passes through an amine unit for removing hydrogen sulfide from the feed gas stream thereby producing a hydrogen sulfide stream and a hydrocarbon enriched stream; and wherein the hydrogen sulfide stream passes through a Claus unit for removing sulfur from the hydrogen sulfide stream removed thereby producing elemental sulfur; e. feeding a second portion of the associated gas stream to a second gas processing plant comprising one or more gas compressors wherein the second portion of the associated gas stream is compressed to form a second compressed associated gas stream; f. increasing a permeate stream pressure of the permeate stream in a permeate compressor or an eductor to form a compressed permeate stream; g. receiving and compressing the second compressed associated gas stream and the compressed permeate stream in a sour gas compressor to form a sour gas injection stream; and h. injecting the sour gas injection stream into a subterranean formation.
