    摘要: The Monte-Carlo method of generating Popcorn shooting patterns starts with the number and sizes of the guns available and the length in time of the desired Popcorn pattern. The firing times and order of the guns will be randomly perturbed and a large number of Popcorn patterns built. Candidate Popcorn patterns will then be tested against a set of criteria to identify acceptable or the best patterns. These criteria may include limits on maximum peak strength, distinctiveness compared to the other patterns, and the size of the notches and peaks in the spectra.

    摘要: So-called “Popcorn shooting”, and especially continuous Popcorn shooting, combined with simultaneous source shooting allows considerable flexibility in producing high-resolution data and in creating source arrays. Using a combination of simultaneous source de-blending and Popcorn reconstruction it is possible to construct using post acquisition processing arrays of any desired length by constructing a popcorn pattern that takes into account the vessel speed and physical arrangement of guns behind the towing vessel.

    摘要: The maximum output of a seismic source array may be reduced by activating the individual seismic sources within these seismic source array in a pattern that is extended in time rather than by the presently employed conventional simultaneous activation of a large number of individual seismic sources. Methods are disclosed which take data shot with patterned sources and may use a sparse inversion method to create data with the about same image quality as that of conventional sources. In this manner the output of the maximum impulse of a seismic source array may be reduced by an amplitude factor of about 10 in the examples shown here, corresponding to a reduction of about 20 dB while maintaining virtually the same seismic image quality. The disclosed methods may be used in combination with any simultaneous sourcing technique. In addition, the disclosed methods may be used with a plurality of source arrays.

    摘要: According to an embodiment, there is provided a system and method of collecting seismic data using a predetermined pattern of source activations that is intended to control the properties of the resulting seismic signal. One embodiment utilizes a seismic source array (or, more generally, any collection of controllable sources) to create a series of spaced apart in time source activations, with the spacing and number of such activations being used to shape the resulting signal. In one method of building sweeps, the guns are fired at an increasing rate (decreasing time separation) as time goes by. Other patterns may be generated by decreasing the firing rate as time goes by, or some combination of the foregoing. In an embodiment, the rate of the increase or decrease in the firing rate will change from pattern to pattern.

    摘要: A portable device, such as a pager-type device or card module, generates and guides a user through a customized smoking cessation plan. The device calculates intervals between smoking events (when the user is allowed to smoke) based on user input information and the day in the plan. The intervals increase as the plan progresses. The device alerts the user when a smoking event occurs. The user may place the device in a silent mode during periods when smoking would be inconvenient.
