Ocean Drilling Program Leg 204 Scientific Prospectus Drilling Gas Hydrates on Hydrate Ridge, Cascadia
During Ocean Drilling Program (ODP) Leg 204, we will drill a transect of sites through the gas hydrate stability zone on the southern part of Hydrate Ridge on the Cascadia accretionary margin offshore Oregon. Massive hydrates are present at the seafloor there, and high-resolution threedimensional seismic data indicate a complicated subsurface plumbing system. The transect will cover two distinc...
متن کاملExperimental Determination of the Temperature Suppression in Formation of Gas Hydrate in Water Based Drilling Mud
The aqueous mixtures of light gas molecules under low-temperature and high-pressure conditions are candidates to form gas hydrate clathrates. The formation of gas hydrate may lead to various problems and extra charges in natural gas production and processing. The presence of hydrate crystals forming a stable solid phase can potentially block the wells, pipes, and process facilities. To avoid su...

In recent years, an increasing number of oil and gas projects involving drilling through salt have been presented by different exploration companies. It is important for underwriters, lawyers, regulators, financiers and engineers to have a clear understanding...
متن کاملIntegrated Ocean Drilling Program (IODP) Proposal GAS HYDRATE ON THE CASCADIA MARGIN
This proposal is for an IODP program to constrain models for the formation of deep sea gas hydrate in subduction zone accretionary prisms. The objectives include the deep origin of the methane, its upward transport, its incorporation in gas hydrate, and its subsequent loss to the seafloor. The main attention is on the widespread seafloor-parallel layer of dispersed hydrate located just above th...
متن کاملUsing an experimental drilling simulator to study operational parameters in drilled-cutting transport efficiency
Inadequate hole cleaning can lead to many problems in horizontal and directional wells. In this work, we tried to investigate the cutting transport phenomenon by an experimental directional drilling simulator, considering the differences between the operational and experimental conditions. The inclination, fluid type (water, foam, viscous, and dense), rotary speed (0 and 110 rpm), nozzle bit si...
