Nickel alloy UNS N07718 (Alloy 718) is extensively used in the oil and gas industry. However, it is limited by NACE MR0175/ISO15156 which only permits use at a maximum of 200 psi (1.38 MPa) H2S partial pressure at 400°F (204°C). To expand the Stress Corrosion Cracking (SCC) safe use limit of Alloy 718, NACE TM0198 Slow Strain Rate (SSR) testing was performed first to identify an upper H2S limit (i.e., 650 psi [4.48 MPa]). NACE TM0177 C-ring testing subsequently qualified Alloy 718 at this high limit in modified NACE Level VII conditions, and also under 910 psi (6.27 MPa) H2S partial pressure in a simulated field environment (total 15 ksi [103 MPa]) based on equivalent dissolved H2S concentration. This is the highest service H2S limit reported for Alloy 718 and also evidence that validates the effectiveness of dissolved H2S concentration as new sour severity metric for Ni alloy SCC qualification.

Route to optimize temporary seal for downhole dissolvable magnesium plug application in HT: Failure analysis and learnings

Product Number: 51323-18889-SG
$20.00

Over the past two decades of the Shale Revolution that completely transformed the global energy market, Fast-dissolving magnesium (DM) alloy technology has advanced significantly in both performance improvement and cost reduction through continuous optimization, which significantly reduced operational costs of hydraulic fracturing. Thousands of tons of DM are manufactured yearly worldwide to make the so-called “multi-stage dissolvable frac plugs”.

The Performance Study of High-Temperature, High-Pressure (HTHP) Corrosion Inhibitors at Sour Conditions

Product Number: MECC23-20051-SG

The oil and gas industry is currently operating numerous fields that contain high concentrations of CO2 and H2S at elevated temperatures. Under such conditions, internal corrosion control has emerged as a significant challenge, leading to severe material failures in production wells and posing a substantial threat to oil and gas infrastructure.


Internal corrosion of pipelines represents a critical risk during the initial stages of production, with a reported occurrence of above 9,000 failures between 1990 and 2012.
