TECHNICAL LIMITS FOR DEVELOPMENT OF NATURAL GAS HYDRATE DEPOSITS
2016In this work we have formulated the set criteria for cost-effective selection of technologies for industrial production of gas from a hydrate deposit, which rely on the properties of hydrate-bearing rock and the geologic properties of the gas hydrate deposit.

Elemental sulphur deposition in natural gas transmission and distribution networks
The Journal of Supercritical Fluids, 2008Deposition of elemental sulphur in natural gas transmission line systems has been reported on only in recent times. The most common location is immediately downstream of a point of significant pressure reduction. A necessary step to eliminate solid sulphur deposition is to understand the deposit mechanism.

Particle deposition in natural gas pipelines using computational fluid dynamics modelling
Asia-Pacific Journal of Chemical Engineering, 2011ABSTRACTSolid particles within natural gas transmission and distribution pipeline systems are known to create varying operational constraints for pipeline operators—from temporary to complete stoppage of the gas flow. The solid particles can be extremely variable, both in composition and origin.

Subsurface Sea Bed Deposits: Petroleum and Natural Gas
1986Subsurface deposits of the sea bed are those contained within the structures of consolidated sedimentary and basement rocks. Basing primarily on the method of their extraction, they can be divided into two groups: (1) petroleum, natural gas, and sulphur, which are extracted through holes drilled into the sea floor and (2) coal, iron ore, and vein ...

Determination of elemental sulfur deposition rates for different natural gas compositions
Journal of Petroleum Science and Engineering, 2015Abstract Natural gas is increasing its share in the worldwide energy market. However, it poses several problems during transportation. The formation and deposition of elemental sulfur (S8) in pipelines is the issue that has the greatest impact on both operational safety and maintenance costs.

Nature of radiometric anomalies above oil and gas deposits
International Geology Review, 1966Negative anomalies in gamma-field over accumulations of hydrocarbons may be explained by weakening of the sorption capacities of rocks under the influence of certain hydrocarbons. In a variety of test areas, including uneconomic "blanks," the radiometric anomalies in the overburden are accompanied by its abnormally low content of potassium, uranium ...

Suiyosei-Ten'Nengasu,"A Special Type of Japanese Natural Gas Deposit"
AAPG Bulletin, 1965The natural gas of accumulations exploited in the Niigata field and in the Mobara and smaller fields of the southern Kanto gas region is not associated in any way with crude oil, but consists of CH 4 (generally over 90 percent) and CO 2 (generally up to 5 percent) produced by bacterial decomposition of organic material in sediments, together with ...

Asphaltene Deposition during Bitumen Extraction with Natural Gas Condensate and Naphtha
Energy & Fuels, 2018Solvent bitumen extraction processes are alternatives to thermal processes with potential for improved economic and environmental performance. However, solvent interaction with bitumen commonly results in in situ asphaltene precipitation and deposition, which can hinder flow and reduce the process efficiency.

Journal of Mechanical Science and Technology, 2011
An original method for estimating fouled deposit thickness on the inside surfaces of natural gas cooler tubes is presented. This method does not require opening and inspecting a cooler as it is based on the measurement of gas cooling degree, i.e. the gas temperature difference between the cooler inlet and discharge.

Genetic Relation of Various Types of Natural Gas Deposits in Japan
AAPG Bulletin, 1964The genetic relation of two types of natural gas deposits in Japan, gas dissolved in water (dry gas) and gas associated with oil (wet gas), is discussed geochemically. Although dry gas is produced in situ, by fermentation in ground water it sometimes transmutes into a free gas phase depending on the suitability of geological structures and the quantity
