Factors Affecting Horizontal Well Gravel-Pack

2006-9-24 · The gravel pack process was simulated and the effectiveness and pack efficiency of the gravel pack job is determined using the simulator. The effect of carrier fluid viscosity on gravel-pack efficiency was studied by varying the viscosity between 1 and 51 cp, injection rate between 1 and 4 barrel per minute, and gravel concentration between 0.50 and 4.0 pound mass per gallon.

Transport Efficiency of High-Density Gravel Packing

The consistency of the slurry is determined by the fluid viscosity, gravel concentration and size. Since the gravel size is dictated by formation sand size, only two of these variables (fluid viscosity and gravel concentration) may be modified for any given gravel-pack job. Annular velocity should have two minor effects on transport efficiency.

Gravel-sand mulch thickness effects on soil

2014-10-1 · In parts of this region, irrigating fields have almost been replaced by the use of gravel-sand mulch on dry land. Extensive research and practical experience have proved that gravel-sand mulch could markedly reduce soil evaporation and increase soil temperature at night as well as reduce soil temperature fluctuations (,,,,). Nachtergaele et al. (1998) determined that gravel mulch causes a

Particle-size effects on soil temperature, evaporation

2010-6-1 · Soil temperature was increased by gravel–sand mulch plus plastic film. The increment of soil temperature was larger especially for 1–4 cm particle size. In the gravel–sand mulch layer having different size particles, the greater percentage being of 2–6 cm pebbles, increases porosity, and lowers soil temperature, and causes more evaporation. The results of the watermelon experiment showed

Gravel Pack an overview ScienceDirect Topics

High-density packing is adopted with a gravel-carrying volume ratio up to 96% (12 lb/gal), that is, 1 m 3 fluid should pack 0.96 m 3 gravel. The other is low-viscosity salt water with a gravel-carrying volume ratio of 8–15% (1–2 lb/gal), which can avoid the possible formation damage induced by the high-viscosity, gravel-carrying fluid.

Well Screens and Gravel Packs Global Journals

2017-12-19 · gravel pack are an absolute necessity if the well draws on unconsolidated sands and gravels–even under composed rock becomes friable and may gradually cave in. The screen and gravel pack should first prevent the collapse of the well due to the abstraction of large quantities of sand and secondly, damage to the pumps

Efficiency of Slow Sand Filter in Purifying Well Water

2014-7-8 · Graded gravel from Labo River was used as support of the sand filter. Gravel with sizes from about 25.5 mm to 31.7 mm, passing and retained in sieves no. 1 ¼ and no. 1 respectively was placed at the bottom of the tank. Gravel passing through sieve no. 1 and retained in sieve no. 3/8 (sizes 9.6 25.4 mm) was placed at the middle.
