H2S/sour gas

A partnership between Saudi Aramco and Baker Hughes will build a plant where they will work to expand the uses of nonmetallic oilfield hardware, beginning with high-performance reinforced plastic pipe.

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.

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.

The laboratory will be used primarily to test the sulfide stress cracking resistance of carbon steel alloys for oil wells and offshore drilling applications.

The paper discusses the main factors affecting CO2 corrosion, provides an assessment of what to look for in major equipment, and details recommended material of construction and corrosion mitigation/control methods.

Although improvements to drilling rigs have allowed drilling to depths greater than 20,000 ft, experience has shown that, the deeper the well, the higher the bottomhole pressure and more hydrogen sulfide gases the lease workers will experience.

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.

Three firms that bought crude oil last year from US emergency stockpiles raised concerns about dangerous levels of a poisonous chemical in the cargoes, according to internal Energy Department emails and shipping documents reviewed by Reuters.

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.

A corrosive gas that is fatal to humans in high concentrations should not be a toxic substance under Canadian environmental law, say federal researchers in a new proposal.
