Abstract: Methods of performing a stimulation operation at a wellsite are disclosed. The wellsite is positioned about a subterranean formation having a wellbore therethrough and zones thereabout. The method involves establishing at least one objective for stimulating production of reservoir fluid from the subterranean formation and into the wellbore. The stimulating involves placing a stimulating fluid along the zones of the wellbore. The objective is based on wellsite data. The method also involves identifying at least one constraint for the stimulating, determining target distributions of the stimulation fluid based on the objective(s) and the constraint(s), and selecting operational parameters for the stimulating based on the constraint(s) and the target distributions. The method may also involve stimulating the subterranean formation using the target distributions and the operational parameters, monitoring the wellsite during the stimulating, and adjusting the stimulating based on the monitoring.

Abstract: This invention relates to a tire having an electrically non-conductive tread which contains an electrically conductive rubber strip which extends through at least a portion of the tread to its running surface in a wave configured shape, and therefore not a continuous straight line within said tread, in which at least a portion of the rubber strip is in a shape of, for example, a substantially sinusoidal, cycloidal and/or zigzag form, to thereby provide a mechanical self-locking configuration between tread segments through which the rubber strip extends and divides. In particular, said tread is composed of a cap/base configuration. The outer cap layer is of a relatively electrically non-conductive rubber composition having a running surface intended to be ground-contacting. The tread base layer, underlying the tread cap layer, is of a relatively electrically conductive rubber composition and is not normally intended to be ground-contacting.

Abstract: This invention relates to the preparation of a multi-layered rubber composite, said composite and a tire having a component prepared thereby. The multi-layered rubber composite is composed of at least two individual rubber compositions configured as at least three parallel aligned alternating rubber layers, wherein each rubber layer extends through the rubber composite thickness from one side to the other opposing side. The multi-layered rubber composite is prepared by co-extruding at least two individual rubber compositions, via an individual extruder for each rubber composition, to an internal cavity of a former. Said former is comprised of an internal cavity which contains a sequence of flow deflectors and channels for guiding the at least two individual rubber compositions to form said multi-layered rubber composite in a single manufacturing step.
