Modeling of Severe Slug and Slug Control With OLGA

SPE Production & Operations, 2006
Summary With the recent developments in the oil and gas industry, in which the number of satellite fields are increasing, the industry faces major challenges. A mixture of gas and oil is transported in multiphase pipelines along the bottom of the sea from the wells and up through the riser to the oil rig. The development of unstable flow

Self-propelling slugs

Journal of Fluid Mechanics, 2002
Surface coating is generally achieved by an active operation: painting with a brush; withdrawing from a bath. Porous imbibition constitutes a more passive way: a porous material just put in contact with a reservoir containing a wetting fluid is spontaneously invaded. In this case, the material can eventually be filled by the fluid. If the aim is to

The Leap-frogging Slug

Nature, 1971
PREVIOUS reports of the life cycle of the slug, Agriolimax reticulatus (Muller)1,4, have maintained that there are two generations a year. A spring generation hatches in March to May and grows during the summer to give rise to an autumn generation which hatches in September to October and this grows during the winter to produce the next spring ...

Dictyostelium Slug Phototaxis

2009
Dictyostelium slugs are able to respond to environmental stimuli in an extremely sensitive and efficient way. This enables a slug to migrate to more favourable locations for formation of fruiting bodies and dispersal of spores. Phototaxis is a readily assayed phenotype and reflects the interactions of environmental stimuli with morphogenetic signalling

Sensitivity of Slug Flow Mechanistic Models on Slug Length

Volume 7: Offshore Geotechnics; Petroleum Technology, 2009
Slug flow is one of the common flow patterns in gas and oil production and transportation. One of the closure relationships required by the multiphase flow mechanistic models is slug length correlation. There are several closure relationships proposed in the literature as function of pipe geometry, pipe diameter and inclination angle, and to a lesser ...

Control of Black Slug and Veronicellid Slug, Hawaii, 1989

Insecticide and Acaricide Tests, 1990
Abstract Efficacy tests were conducted from Mar to Jun at the University of Hawaii at Hilo, College of Agriculture, Hilo, Hawaii. Chrysanthemum seedlings were planted in nursery flats (17 × 19 inches) containing a cinder and peat (1:1) media and grown under greenhouse conditions for two months.

Biocontrol of slugs: Effects of slug parasitic nematodes and bacterial metabolites on harmful slugs

2023
The effects of combining secondary metabolites produced by Xenorhabdus bacteria with slug parasitic nematodes belonging to the genus Phasmarhabditis on the pestiferous slug species Arion vulgaris were investigated. Secondary metabolites from ten different Xenorhabdus strains were tested and their slug repellent effects as well as their impact on the ...

Slug Testing For Pumping Wells

Annual Technical Meeting, 1990
Abstract This paper proposes a variation of ‘slug test’ for sucker-rod pumping oil wells. Application of slug testing simply expedites the buildup process. A slug test is conducted by admitting a slug of reservoir liquid such that the hydrostatic head of the wellbore liquid column balances the reservoir pressure ...

The effects of food and slug density on slug movement

2010
I investigated the effects of food, crowding, and weather on the behaviour of the slugs, Arion ater and Ariolimax columbianus. Field experiments demonstrated that Arion based its migratory response on the density of conspecifics and the quality and quantity of available food.
