Corrosion Will Occur, Whether You Like It or Not
Just like Houston’s summer heat, corrosion of metal surfaces will occur—whether you like it or not. To help you better understand corrosion, these papers describe using water surveys in a production/injection plant, testing the effectiveness of mitigation, and data evaluation using machine learning.
Water Survey Assesses Souring and Corrosion at Production/Injection Plant
At a water treatment plant for an onshore oil field in northern Germany, formaldehyde injection was started in 2015 as a biocide. The goal of this study was to understand the chemical parameters and microbial distribution in the water system and whether formaldehyde injection was effective.
ADNOC and CNOOC To Collaborate in Upstream, Downstream, and LNG
ADNOC and CNOOC will explore multiple new opportunities for collaboration across the upstream and downstream sectors in the UAE and China.
Southwest Research Institute To Open Corrosion-Testing Facility
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 Effect of CO2 Injection on Corrosion and Integrity of Facilities
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.
Managing Experimental-Data Shortfalls for Fair Screening at Concept Selection: Case Study To Estimate How Acid-Gas Injection Affects Asphaltene-Precipitation Behavior
This paper focuses on a numerical-modeling analysis of the acid-gas-injection (AGI) scenario in carbonate HP/HT reservoirs, and presents the way in which AGI impacts asphaltene-precipitation behavior.
Underground Bacteria Generates H2S and Trips Control Panels
When panels in an instrument equipment shelter kept tripping and the occasional smell of H2S led to an investigation of the rationale. Although a rare occurrence, this paper presents a strategy for prevention through careful site selection.
Taking on the Technical Challenges of Sour Gas Processing
High H2S and CO2 content in natural gas pose significant challenges to processing equipment. This article explores the challenges of sulfur removal and high pressures in the presence of acid gas.
Case Study—Calcium-Carbonate-Scale Inhibitor Performance Degradation Because of H2S-Scavenger Injection in Semoga Field
Semoga and Kaji fields experienced reservoir souring and suffered a history of calcium-carbonate (CaCO3) -scale cases before a proper scale-inhibition program was implemented. Problems with a free water knockout discovered continued scale issues, leading to investigation of the reasons.
Processing of Sour Natural Gas Reaches New Highs
ExxonMobil is testing its Controlled Freeze Zone technology, a single-step cryogenic process that allows carbon dioxide (CO2) to freeze in a controlled method and then melts the CO2. After recovery of the methane, the CO2 can be sequestered or used for EOR.
