Abstract: Method of hydraulic fracturing of a subterranean formation comprising drilling a deviated wellbore in a direction parallel to a desired fracture direction, and supplying fracturing fluid through the wellbore to the formation. The average net pressure on the fluid is maximized in a fracture formed in the formation by pumping the fracturing fluid at a maximum rate, and by using a high viscosity fracturing fluid. Maximization of the average net pressure acts to extend the fracture in a direction parallel to the direction of the wellbore. The amount of the extension of the fracture is a function of the ratio of the average net pressure to the horizontal stress difference, whereby the higher the ratio, the greater the amount of the extension.

Abstract: The invention relates to a mold apparatus and a process for forming a lid latching mechanism in a thermoplastic container. The lid latching mechanism features a large, trapezoidally-shaped opening hole. The trapezoidal shape has been found to reduce the amount of tearing that can occur along the edges of an opening formed during the thermoforming process. The opening is created by the engagement between a fixed shear key mounted in a first mold member and a movable shear key which has a trapezoidally-shaped cutting surface and is mounted in a second mold member. The movable key travels along an inclined path as the mold members close on a preheated thermoplastic sheet to form a container.

A transition metal component such as titanium tetrachloride is then incorporated into the support in a specific ratio to the magnesium and silane components. Activation of this catalyst precursor with a trialkylaluminum compound results in a catalyst which is effective for the production of ethylene copolymers.
