Sentence examples for overburden layers from inspiring English sources
The input data includes wellbore configuration and reservoir characteristics such as porosity, permeability, stress and thickness profiles of the pay layers as well as the overburden layers.
The velocity of the P- and S-waves were acquired and interpreted using SeisImager Software Package, then the results were used to build a velocity-depth model to estimate the depth to the bedrock and the thicknesses of overburden layers.
The overburden layers are thus zones of probable risks to aquifer contamination.
Even though these issues need to be resolved, the modeling results could be useful for analysis of the stress and strain in overburden layers in this project.
The cut-off wall in a clay-core rockfill dam built on a thick overburden layer is subjected to a large compressive pressure under the action of the loads such as the dead weight of both the dam and the overburden layer, the frictional force induced by the differential settlement between the cut-off wall and surrounding soils, and the water pressure.
Sonic drilling is a fast and efficient method for the undisturbed sampling of soft soils and is widely used in overburden layer drilling such as in soft soil and gravel.
In this paper, numerical analysis of a core rockfill dam built on a thick overburden layer was conducted and some factors influencing the stress-strain behaviors of the cut-off wall were investigated.
The result shows that improving the overburden layer, selecting plastic concrete with a low modulus and high strength, and optimizing the connection between the cut-off wall and the clay core of the dam are effective measures of reducing the deformations and compressive stresses of the cut-off wall.
The factors include the improvement of the overburden layer, the modeling approach for interfacial contact between the cut-off wall and surrounding soils, the modulus of the cut-off wall concrete, and the connected pattern between the cut-off wall and the clay core.
SAGD simulation was started in layer D underling by layer C. Subsequently, a producer in the later layer at bottom, separated by marlstone, started to produce while this zone had been heated by conduction of overburden, layer D, by expanded steam chamber.
To solve problems caused by great measuring depth and extra thick overburden soil layers in the mine, a series of improved techniques were developed for the traditional hydraulic fracturing technique and equipment to increase their pressure-enduring ability and to ensure safe and flexible removal of the sealing packers with other experimental apparatus.
