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.
