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 14):
A method of retrofitting an integrated oil and gas production plant including 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, a compressor for boosting pressure of the associated gas stream, a hydrogen sulfide removal unit comprising an amine unit and/or a Claus unit for removing hydrogen sulfide from the associated gas stream and a sour-gas injection unit for injecting a sour gas injection stream into a subterranean formation, comprising:\n adding a hydrogen sulfide-selective membrane downstream of the compressor to remove hydrogen sulfide from 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; such that less hydrogen sulfide is sent to the compressor and hydrogen sulfide removal unit than in the integrated oil and gas production plant without the hydrogen sulfide-selective membrane and the integrated oil and gas production plant has an increased oil and/or gas production rate as compared with the integrated oil and gas production plant without the hydrogen sulfide-selective membrane.
