In a previous study using a single wellbore production system, it was demonstrated that a combination of depressurization and wellbore heating is more efficient than depressurization alone, where the endothermic dissociation process rapidly consumes
Measuring the in Situ Hydrate Saturation from γ-Ray Transmissivity Changes during Local Dissociation

The worldwide abundance of gas hydrates in areas with engineering activities highlights the need for an accurate understanding of how much hydrate the soil contains, before any subsequent assessments are made. For the currently deployed gas hydrate s

Depressurization experiments of methane-hydrate-bearing sediments were conducted to measure changes within the hydrate stability region before dissociation started. Pore-filling hydrate with a saturation of about 40% was formed in water-saturated sil

Natural gas hydrates are increasingly encountered in offshore projects as they move into ever deeper water. Occurring from the seabed until several hundred meters in depth, hydrates are metastable, and dissociate back to gas and water if their high p

To extract gas from hydrate reservoirs, it has to be dissociated in situ. This endothermic dissociation process absorbs heat energy from the formation and pore fluid. The heat transfer governs the dissociation rate, which is proportional to the diffe

The Changbei basin centred gas reservoir is located in the Palaeozoic clastic sandstone of the Shaanxi formation, Ordos basin, P.R. China. After more than a decade of successful tight gas production history, the development of the field is being expa

In this paper, a method is proposed to determine the fracture toughness of brittle and heterogeneous material through hydraulic fracturing. The intent of the proposed method is to deploy it on materials whose are not easily determined by standard tes

The Zhahaquan tight oil field is located in the late tertiary siltstone of the Qaidam Basin, Gansu Province, P.R. China. The field's conventional and tight reservoirs are currently being appraised with an aggressive drilling campaign. Despite an aver

Sub-sea well intervention in deep water is generally being conducted from mobile offshore drilling units using conventional drilling risers. To reduce cost, light well intervention (LWI) solutions using mono-hull vessels are being investigated. One o

Large amounts of gas hydrates are deposited in marine sediments and permafrost regions in many parts of the world. Their potential as a future energy source, but also as a geohazard and contributor to global warming has raised people's interest. The
