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 1):
A system 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. a separator for separating 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. an associated gas compressor for compressing a first portion of the associated gas stream to form a first compressed associated gas stream; c. 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. a first gas processing plant for receiving a feed gas stream comprising the retentate stream and a portion of the oil stream from the separator, wherein the first gas processing plant includes an amine unit for removing hydrogen sulfide from the feed gas stream and producing a hydrogen sulfide-enriched stream and a hydrocarbon-enriched stream; and a Claus unit for producing elemental sulfur from the hydrogen sulfide-enriched stream; e. a second gas processing plant for receiving and compressing a second portion of the associated gas stream and a portion of the oil stream from the separator to form a second compressed associated gas stream, wherein the second gas processing plant includes one or more gas compressors; f. a permeate compressor or an eductor for increasing a permeate stream pressure of the permeate stream to form a compressed permeate stream; and g. a sour gas compressor for receiving and compressing the second compressed associated gas stream and the compressed permeate stream to form a sour gas injection stream for injecting into a subterranean formation.
