Abstract: A composite slip wedge for a frac plug or bridge plug used in oil and gas production has a tapered wedge surface. A first portion of the slip wedge is formed of layers of fibers entrained in an epoxy matrix, in which the layers are directed generally parallel to an axis of the plug. The second portion of the slip wedge has layers of fibers that are inclined relative to the plug axis. The second portion is at or adjacent the tapered wedge surface so that a set force applied to the tapered wedge surface in a direction parallel to the plug axis is directed transverse to the fiber layers in the second portion of the slip wedge.

Abstract: A composite downhole tool, such as a frac plug or a bridge plug, having a composite sleeve located around a composite mandrel and defining an overlapping or overlapped section between the two. One or more shear pins with each shear pin having a pin hole is provided with the downhole tool to reinforce the downhole tool from interlaminate shear. The one or more shear pins can further be reinforced from rotation by overlapping at least part of the one or more pins with a lip of a ring.

Abstract: A networked system of terminals and servers includes one or more customer terminals, one or more customer service expert terminals and communications links enabling communication between selected ones of the customer and expert terminals. Each of the customer and expert terminals supports two-way transmission of audio, video and other data. A peer-to-peer link is established between the selected customer and expert terminals to facilitate communications. Selected data are sent through a system server. The system thereby enables customers and experts to interact with each other in a natural conversational manner. The system thereby enables businesses and other organizations to provide effective customer support to there customers wherever located, using a customer support staff that need not be physically located at the customer's location.
