Acoustic Properties of Shallow Seafloor Gas

Offshore Technology Conference, 1989
ABSTRACT In many ocean regions including the continental shelf and slope of the Gulf of Mexico, the presence of gas bubbles and gas hydrates significantly influences the acoustic properties of the seafloor sediment.

Unconventional Shallow Biogenic Gas Systems

AAPG Bulletin, 2002
Abstract Unconventional shallow biogenic gas falls into two distinct systems that have different attributes. Early-generation systems have blanketlike geometries, and gas generation begins soon after deposition of reservoir and source rocks.

Shallow Gas Development: Stimulation Fluids

Journal of Canadian Petroleum Technology, 1996
Abstract The stimulation treatments for a 40-well Medicine Hat Shallow Gas Project developed by Husky Oil Operations Ltd. are discussed. Field application. of the stimulation designs is presented. Laboratory test results of newly developed breaker technology are also presented.

Shallow Gas Blowout Kill Operations

Middle East Oil Show, 1991
ABSTRACT Shallow gas blowouts, as a general class, are the most difficult type of blowout to kill. This paper discusses current industry myths about shallow gas, typical results from a shallow gas blowout that affect the kill operation, kill options and selection criteria, rig selection criteria, and well killing guidelines.

Mini 3D for shallow gas reconnaissance

Offshore Technology Conference, 1996
Abstract The Mini 3D project was undertaken by TOTAL and ELF with the support of CEPM (Comite d'Etudes Petrolieres et Marines) to define an economical method of obtaining 3D seismic HR data for shallow gas assessment.

Practice of Ultra-Deepwater Shallow Well Construction in Nature Gas Hydrate and Shallow Gas Formation

GOTECH
Abstract Due to the large water depth and geological structure, a large amount of nature gas hydrate (NGH) and shallow gas are buried in the shallow layer in the deepwater area of the South China Sea. Conventional deepwater oil and gas well design faces the risk of wellhead subsidence and collapse, which led to a greater risk of well ...

Gas distribution in shallow packed beds

Industrial & Engineering Chemistry Research, 1993
A shallow packed bed is defined as one where the bed diameter is greater than the packed height. Some shallow packed beds are more than 510 m in diameter. It is shown that gas distributors may be developed and evaluated in the laboratory by measurements of air flow through a geometrically similar model of the full-scale plant.

Analysis of Shallow Gas in the Ekofisk Area

Proceedings, 2014
Analysis of shallow gas in Quarternary sediments in the Ekofisk area has been done using time-lapse amplitude interpretation and AVO analysis. A major underground blowout occurred in this area when drilling the 2/4-14 well into a Jurassic target in 1989, and huge amounts of gas leaked into shallow layers.

The evidence of shallow gas in marine sediments

Continental Shelf Research, 1992
Abstract Evidence of the presence of shallow gas is considered here under the following categories: seismic sub-bottom signatures, geochemical signatures and indirect features on and above the seabed. The various forms of evidence indicate that gas has migrated and may still be migrating through the seabed, and therefore implies that gas within ...

Gas combustion in shallow fluidised beds

Applied Energy, 1975
Abstract Combustion of premixed gas and air in shallow fluidised beds is described and some of the limits set by gas velocity and particle size are discussed. There is a lower limit of gas velocity below which heat transfer back to the distributor plate causes excessive preheat leading to pre-ignition and to temperatures well above the equilibrium ...
