... velocity, density, compressibility, and Joule-Thomson coefficient). A pulse-echo technique was used to measure the sonic velocity in CO2, methane, and their mixtures (containing 5 - 30 mol% CO2) in the pressure range of 1 – 200 bar and in temperaturerange of 300 – 323K. The corresponding density...

... gas compositions, including compressed air, methane, nitrogen, and carbon dioxide are analyzed for their suitability as gas lift agents. Application of the gas lift results in up to a 30% increase in liquid production rates. Methane exhibits superior performance due to its lower density...

... Abstract The study explores the use of thermo-catalytic decomposition (TCD) of methane to produce hydrogen (H2) and solid carbon. The research focuses on the performance of a proprietary molten metal catalyst in a TCD reactor, evaluating methane conversion efficiency and carbon quality under...

... in young reservoirs by 1) FHZ equation of state (EoS) asphaltene gradients and cubic EoS modeling of solution gas for reservoir fluids, 2) analysis of liquid-phase geochemical biomarkers, and 3) methane carbon isotope analysis. Specifically, in the common charge of primary biogenic gas and oil...

... A new concept is the in-situ hydrogen production directly from natural gas reservoirs. The idea is to initiate methane cracking and methane-water reactions for hydrogen production in reservoirs using thermochemical methods. Once hydrogen gas is generated, a downhole H 2 membrane separator...

... Abstract Methane is an invisible greenhouse gas predicted to account for over 30% of global warming over the next decade. A substantial portion of the methane emissions from oil and gas (O&G) facilities arise from events that are intermittent. Continuous monitoring using methane emissions...

... reforming, it is the method that is most frequently used. While other resources are being transformed to produce 30% of the hydrogen needed for the world, methane reforming makes up 48% of the total. The steam reforming process has one of the greatest production efficiencies of all currently commercially...

..., Process Compressed Air Pneumatics (CAP) is an innovative technology that replaces the methane emissions of pneumatic devices with clean, dry, compressed air. By employing highly reliable free-piston Stirling engine technology the end-user utilizes a small fraction of the normally vented methane...

... modifications. A generic well was used to study the differences between a CO2 well and a hydrocarbon (methane) well with respect to design and procedural changes in case of a well control incident. A well control simulator capable of transient multiphase modeling of hydrocarbon and CO2 systems was used...

... Abstract Steam methane reforming (SMR) technology generates about 95% hydrogen (H 2 ) in the United States using natural gas as a main feedstock. While hydrogen is clean, the process of hydrogen generation via SMR is not, as it emits about 10 times more carbon dioxide (CO 2 ) than hydrogen...

... Abstract A Seneca Resources Company, LLC (Seneca) natural gas well in Pennsylvania was leaking methane from both the 13-3/8 in × 9-5/8 in (55 psi) and the 9-5/8 in × 7 in (85 psi) cemented annuli. Previous attempts to mitigate the problem had proven unsuccessful, which prompted the trial...

... analysis, commonly known as Mud Gas Isotope Logging (MGIL), provides continuous sampling of stable carbon isotopes of methane (δ13C1), ethane (δ13C2), and propane (δ13C3). The service, performed with a GC-C-IRMS analyzer, was proven and validated for an operator through two case studies. 98 The first case...

... analyzed for their isotopic signatures. The results demonstrate that carbon isotopic composition of methane to pentane can be used as fingerprinting tool to identify different sources of gas. The studied gases are all of a thermogenic origin and were generated from Type-II marine source rocks. Mixing...

... will be blocked by the accumulated liquid and will also not produce. This work investigates the effects of gas injection (such as methane, carbon-dioxide, and nitrogen) and steam at high temperatures on one of the Egyptian retrograde gas condensate reservoirs. Several gas injection scenarios that comprise...

... Abstract With atmospheric methane concentrations rising, spurring increased social concern, there is a renewed focus in the oil and gas industry on methane emission monitoring and control. In 2019, a methane emission survey at a bp asset west of Shetland was conducted using a closed-cavity...
