Abstract: An electrical cord having improved safety features comprises a plug having a body portion surrounding respective ends of first, second, and third electrical wires. A live receptacle is in electrical communication with the end of the first electrical wire. A neutral receptacle is in electrical communication with the end of the second electrical wire. A ground receptacle is in electrical communication with the end of the third electrical wire. The body portion surrounds and maintains the live, neutral, and ground receptacles in spaced apart orientation corresponding to blades on an electrical plug. Multiple indicator lights are provided to indicate various states of the plug in which electricity is supplied to the plug.

Abstract: Methods for determination of pay saturation (SPAY) and water saturation (Sw) from surface seismic data use amplitude changes with angle of incidence in conjunction with rock property relationships to determine pay saturation for a variety of situations. These situations include cases where P-P data is used and anisotropy and absorption are negligible; cases where P-P data is used and anisotropic effects are important; cases where contact events are evident; and cases where P-S data is used and anisotropy and absorption are negligible.

Abstract: Seismic reflection events are enhanced by separating the events from seismic data, increasing the amplitude of the events, and adding the events back into the seismic data.
