Sand production is a complex phenomenon caused by the erosion of borehole walls during extraction hydrocarbons. In this paper, sanding process in typical Thick-Walled Hollow Cylinder (TWHC) test numerically simulated. The main objective study to model particulate mechanism sand granular assemblies with different bonding conditions and examine effects parameters such as stress level cavity size ...

Sediment caps that degrade contaminants can improve their ability to contain contaminants relative to sand and sorbent‐amended caps, but few methods to enhance contaminant degradation in sediment caps are available. The objective of this study was to determine if powered carbon electrodes emplaced within a sediment cap could create a redox gradient and provide electron donor fo...

Two field tests and one lab test were conducted to examine the environmental factors affecting sporophore production in Typhula phacorrhiza and to compare these results with those documented for T. ishikariensis and T. incarnata. In the 2001 lab test where lighting, soil moisture, and soil-sand media were tested in 50 mL screw-cap tubes incubated at 4 degrees C, the limiting factor for Typhula ...

The co-culture of juvenile sea cucumber Holothuria scabra (Jaeger), or 'sandfish', with juvenile blue shrimp Litopenaeus stylirostris (Stimpson) was tested by growing groups in co-culture and monoculture for 3 weeks in tanks with enriched sand substratum. Feed was supplied on trays, accessible only to shrimp. Survival of shrimp and sandfish was high in all treatments (73–100%). Growth of shrimp...

Wind erosion is considered a major global environmental problem. Dust storms from the migration of sand dunes can seriously damage civil, industrial, and agricultural areas and a method to stabilize these sand dunes is mulching. The present study investigates the feasibility of using organic wastes of Press mud and Dunder with clay for the production of environmentally-friendly mulches. Sandy s...

The suspension feeding bivalve Austrovenus stutchburyi is a key species on intertidal sandflats in New Zealand, affecting the appearance and functioning of these systems, but is susceptible to several environmental stressors including sedimentation. Previous studies into the effect of this species on ecosystem function have been restricted in space and time, limiting our ability to infer the ef...

Abstract Sand or fine is a typical product in many processing of oil production from unconsolidated and weakly consolidated formations. High variation situ stress, fluid rate above maximum sand-free rate, water are main primary sources the sand production. can cause hazardous operational problems to facilities, pipes, wellbore. Hence, it significant problem that requires be managed studied. To ...

casing material or soil (casing) is used in mushroom (agaricus bisporus) culture to cover a nutritional composted substrate colonised with mycelium, and has an essential function in stimulating and promoting the development of sporophores (fruit bodies). in order to use the agricultural by products (different wastes) to reduce peat consumption of casing soil in button mushroom production, an ex...
