Abstract: A method of geophysical exploration in a seismic survey includes acquiring a set of seismic traces based on seismic data obtained by a seismic receiver, responsive to seismic energy reflected from a subsurface geology. Additional steps include performing reverse time migration on the seismic traces using a velocity model that represents velocity of the seismic energy propagating through the seismic medium. The migrated gathers have an amplitude based at least in part on the migration, which can be corrected by computing synthetic seismograms to provide compensated gathers. Amplitude versus offset and/or amplitude versus angle analysis can be performed on the compensated gathers, in order to generate a seismic image of subsurface structures in the survey area.

Abstract: A zeolite catalyst from ZSM-5 modified with phosphorus, rare earth elements and pore structure regulator is used for methanol/dimethyl ether conversion to light olefins.High temperature, non-recycling, continuous-running process is realized in the reactor system, comprising a dehydration reactor and several (2-n) adiabatic, fixed bed cracking reactors, loaded with the catalyst in multi-stage packing and operated in reaction regeneration cycles. The catalyst possesses high activity, high selectivity, good hydrothermal stability and long reaction life time.Operation of 100% methanol conversion and >85% C.sub.2 -C.sub.4 selectivity has been performed in a reactor system of the scale 0.7-1 ton CH.sub.3 OH/day for >600 hours on stream and with reaction time of single cycle >24 hours.
