Panelists of the recent World Oil Webcast "CCUS: Best Practices for Well Construction and Design" answer questions covering the unique technical and regulatory challenges surrounding CCUS well design as these projects continue to gain momentum in the energy industry.
In the selection of materials for Carbon Capture and Storage (CCS), there is a tendency to rely upon existing knowledge and experience from oil & gas production. However, CCS presents a unique set of conditions and challenges in identifying suitable and cost-effective materials.
Corrosion Resistant Alloys has developed CRA 2550E Grade 140, which satisfies the quality requirements of API 5CRA/ISO 13680 and NACE MR0175/ISO 15156 for sour service. Assuring compliance to these specifications requires a very restrictive range of mechanical properties.
Historically, acid gas injection well completions have typically consisted of low alloy steels internally plastic coated or fiberglass lined. However, costly workovers and environmental have caused operators and engineering companies to reevaluate these well completions. CRA often supports engineering companies in these evaluations, helping determine the ideal metallurgy based on the operator's goals and expectations. […]
There are several methods by which seamless pipe may be produced. The two major categories, hot working and cold working, are differentiated by whether they are performed above or below the material’s recrystallization temperature. Deformation below the recrystallization temperature results in cold hardening and the resulting increase in strength is retained.
Reducing environmental impact is now an essential part of the future strategy for major energy companies worldwide. Increased resources and investment are being injected into the energy transition as companies turn to more renewable forms of energy. However, it's widely acknowledged this energy transition will take time. With the world still very much reliant on conventional […]
The microstructure of cold hardened nickel alloys plays an important role in toughness, corrosion resistance, and environmental cracking resistance. The microstructure plays a much lesser role in strength and ductility, which are more directly related to the cold work imparted. The manufacturing of cold hardened tubulars begins with an as-cast ingot of the required chemical […]
