The validity of the standard quasiparticle approximation is tested by treating the complex self-energy in nuclear matter self-consistently. Hole-hole propagation is ignored. The real part of the mass ...operator is modified only slightly for both hole and particle states. Therefore the binding energy/saturation density problem remains unaltered. The imaginary part of the mass operator changes noticeably for particles propagating substantially above the Fermi surface. This effect may be relevant in determining the absorptive part of the optical potential for intermediate energy scattering.

With today's emphasis on the environmental impact of drilling operations, minimization of drilling fluid and drill cuttings waste is critical. This can be achieved using proper solids removal ...equipment -- such as high performance shale shakers, hydrocyclones, and centrifuges -- and proper pre-well planning. The method described here is founded in decision matrix theory and focuses on several key variables. These include well parameters, the drilling program, logistics, environmental issues, rig selection, expert advice and cost.
