Filed: 2008-11-19
Abstract: A vehicle arresting device comprises a net intended to be laid flat on the ground in the path of a target vehicle with an array of upwardly-directed spikes attached to the net along a leading portion, so that when a vehicle runs over the device some of the spikes engage in its front tires and the net is caused to wrap around the front wheels, being pulled tight under the vehicle to prevent further rotation of those wheels.  There are two rows of spikes, with the spikes in the second row being substantially longer than the spikes in the leading row. The gauge of the netting also varies, with the leading strip which includes the shorter spikes and back towards the longer spikes being of a thinner gauge, the portion from the longer spikes back to approximately the mid length of the net being of a thicker gauge, and the trailing portion reverting to the thinner gauge. These measures help to ensure that the net is capable of arresting a wide range of vehicles, from passenger cars to trucks.

Abstract: The invention is used for determining dimensions of cracks formed by a formation hydraulic fracture. The inventive method for determining the size of a crack consists in producing a numerical model of the displacement of a hydraulic fracturing fluid from the crack and a filtrate area by a formation fluid for a specified formation parameters, hydraulic fracture data and possible crack size for calculating the modifications of a fracturing liquid content in a total production while bringing a well into production after the hydraulic fracture, in periodically sampling of the producible fluid from a hole mouth when starting the well operation during the entire time of pumping the hydraulic fracturing fluid, in measuring the content of the hydraulic fracturing fluid in the samples, in comparing the results of measurement with the model calculations and in determining the crack length on the basis of the best agreement between the results of measurement and said model calculations. When a polymer-based liquid is used in the form of a hydraulic fracturing fluid, the inventive method also consists, for carrying out a numerical calculation, in calculating the modification for a polymer concentration in an extracted hydraulic fracturing fluid in terms of time, in additionally measuring the polymer concentration in the samples and in determining the crack width by comparing the results of measurement with the model calculations.
