Paper presented at the Offshore Technology Conference, May 6–9, 2024
Paper Number: OTC-35173-MS
... for economical aspect, but safety shall be prioritized. The major safety issue in CO 2 injection platform compared to oil & gas platform is CO 2 solidification; dry ice and CO 2 hydrate ( Zhou and Wang, 2014 ). Dry ice is solid phase of CO 2 , and the liquid CO 2 and vapor CO 2 can be solidified via...

... of natural gas hydrate (NGH). Previous research has confirmed the positive impact of radial wells on enhancing the efficiency of NGH exploitation. However, the impact of radial wells on the reservoir intensifies pressure transmission and hydrate dissociation during the hydrate extraction process...

... no different than those used for oil- or gas-well blowouts. The thermodynamic characteristics of CO 2 were on display though. Hydrate formation in blowout preventers (BOPs), expulsion of ice chunks and the formation of water-vapor fog clouds around well sites were all observed. But previous success...

... Cassar et al. (2015) conducted experiments in a multiphase Lyre pilot loop under gas-dominant conditions, without the use of additives. The study involved hydrate formation in multiphase flow, exploring the impact of different flow patterns on hydrate formation and plugging. Tests were conducted...

... Abstract South China Sea hydrate reservoirs, mostly weakly cemented silty sandstones, are prone to landslides during extraction. Prior studies have inadequately considered factors such as dynamic decomposition of hydrates during depressurization, and the impacts on the reservoir's geomechanical...

... assurance aspects that are beyond the standard welltest playbook. Several failures and operational issues related to flow assurance such as the plugging of pipelines and/or tubing by wax or hydrates have hindered the interpretability of data, compromised well test objectives, significantly increased...

... transfer across process facilities especially in low-temperature regions, where oil and gas produced contain more wax as fields mature, and hydrates form at certain temperatures and pressures in facilities transporting acidic gases produced along with hydrocarbons. This study undertook a mechanistic...

Paper presented at the Offshore Technology Conference, May 1–4, 2023
Paper Number: OTC-32322-MS
... Abstract Wellbore integrity in a gas hydrate bearing formation during drilling and production is a great challenge in the energy industry since a complex thermal-hydraulic-mechanical interaction with decomposed solid hydrate process is involved. A wellbore temperature increase...

Paper presented at the Offshore Technology Conference, May 2–5, 2022
Paper Number: OTC-31998-MS
... THIs are the most widely used gas hydrate inhibitors, but the high cost associated with transportation and storage, as well as the low flashpoint temperature (flammability), toxicity, the need to have a recovery unit and possible scale precipitation all present challenges for field applications...

... is applied to the surface. A cleaning surface treatment was then run through the pipe between two pigs to bring the surface to a NACE 4 standard surface preparation. Abstract Gas hydrates, waxes and asphaltenes represent some of the most significant flow assurance challenges, especially in subsea lines...

... The tool is the result of collaborative work with the University of Western Australia's (UWA) Center for Energy. It tightly integrates two models. The first is amultiphase thermal-fluids model –already widely deployed in the industry as an online tool but, thus far, without a hydrate kinetics...

... is below 1500psi. Several wells which have low liquid rate flowing colder with the CTGL due to the Joule Thompson-effect elevated the risk of hydrate formation. Monitoring of Wellhead Temperature (WHT) alone can be a challenge since WHT is below ambient and indication of WHT increase can be interpreted...
