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.
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.
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 […]
Corrosion resistant alloys are metals engineered to resist degradation by oxidation or other chemical reactions. The most common cra’s, used for mild to moderate corrosion resistance, are stainless steels. Stainless steels are iron-based alloys containing a minimum of 10.5% chromium, which is sufficient to prevent rust under typical room temperature atmospheric conditions. Stainless steels simply […]
Regular API 5CT carbon Steel OCTG is fitted with a Glass Reinforced Epoxy (GRE) inner tube for an economical OCTG purchase option for corrosive, aggressive, and normal environments in both production and injection wells. GRE pipe technology is well used throughout the industry and is a Discontinuous Filament Winding process using high-strength fiberglass and amine […]
