Abstract: The present invention is related to a downhole device for hydrocarbon producing wells without conventional tubing (tubingless completion), which improves the hydrocarbon production (gas, oil and condensate), selectively controls produced solids (reservoir sand and hydraulic fracture proppant) and eliminates liquid loading. The device of the present invention is designed according to selected well and reservoir characteristics by an integral methodology which includes the stages: data collection and analysis of the well operating conditions, selection of candidate well, sampling and analysis of produced solids, simulation of production conditions, design and manufacture and installation.

Abstract: Disclosed is a collapsible heated elastomeric bladder tool for repairing damage to composite structures. The elastomeric bladder tool can be used to repair composite structures in difficult to reach areas, such as under stringers used to stiffen large structures. The elastomeric bladder tool can be inserted into the damaged cavity such as a stringer to support uncured plies during the repair on either surface of the cavity. Integrated heating elements within the elastomeric bladder tool provide heat to cure the plies. The elastomeric bladder tool features a collapsed cross section that facilitates installation and extraction.

Abstract: A flow pattern enhancer system mainly for gas-producing oil wells with liquid load problems, comprising mechanical elements that atomize the liquids accumulated at the bottom of the well facilitating their transport to the surface, by decreasing frictional pressure drops and weight of the hydrostatic column.
