Intermittent Gas Lift Used in Hydrate Mitigation and Flare Reduction in Algeria
Hassi Messaoud is a mature oil field with more than 1,100 production wells. Approximately half of the wells are natural flow and the other half use continuous gas lift (CGL) with concentric (CCE) strings.
Novel Approach to Sour-Gas Treatment Lowers Cost and Limits Safety Hazards
This paper investigates novel approaches to sour-gas treatment for use in the Middle East that are outside the common oil and gas market and compares them with traditional techniques.
Multireservoir, Multinetwork Production Optimization of an Omani Reservoir
In the complete paper, a new, fully coupled implicit tool was used to model an onshore Omani asset with multiple reservoirs, each featuring different fluids and multiple networks.
Hybrid Solvent Helps Ease Bottlenecking in Natural-Gas Plant
Processing sour natural gas is a challenge. If mercaptans are present in the sour gas, the limited mercaptan-absorption capacity of the well-known alkanolamine solvents can be a problem.
Foamer Developed To Help Corrosion, Scale Inhibition
A look at the challenges in creating a foamer with corrosion and scale inhibition properties for application in wet-gas production.
Determination of H2S Partial Pressures and Fugacities in Flowing Streams
An Excel-based tool was developed that uses cubic-equation-of-state (EOS) and thermodynamic electrolyte-chemistry modeling to assess sour-production streams.
Production-Logging Tools Facilitate Well Testing in Challenging Environments
The Pugang gas field, one of the biggest inland gas discoveries of the last decade in China, has hydrogen sulfide (H2S) concentrations as high as 10%, making surface- and downhole-facilities design and execution challenging.
Corrosion and Scale Formation in High-Temperature Sour-Gas Wells
Sour gas is being produced from a number of carbon-steel-completed wells in the US, Canada, France, and Saudi Arabia.
Effective Well-Integrity Management in a Mature Sour-Oil Field
A large mature onshore Saudi Arabian oil field is producing sour crude oil that multiplies well-integrity challenges.
Wireless H2S Sensor Uses Nanotechnology To Improve Safety In Oil and Gas Facilities
This paper demonstrates a small, low-cost, low-power, highly sensitive nanomaterial-based gas sensor specifically targeted for the detection of hydrogen sulfide (H2S).
New Casing Valve in a Deep-Well Sour Environment
This paper describes the first application of the 10¾-in. CV in a deep-well sour environment.
Controlled-Freeze Technology for Processing Sour-Gas Resources
A single-step cryogenic-distillation process that removes carbon dioxide (CO2), hydrogen sulfide (H2S), and other impurities from natural gas has been developed by ExxonMobil.
