Conversion of oxygenates to lower olefins in a turbulent fluidized catalyst bed

Abstract: Conversion of oxygenates to lower olefins is improved by operating a fluidized bed of zeolite catalyst in a turbulent fluidization regime at elevated temperature and controlled catalyst activity.

Method for monitoring the hydraulic fracturing of a subsurface formation

Abstract: A method for monitoring the hydraulic fracturing of a subsurface formation. The formation is fractured with a fracturing fluid or a proppant containing a characteristic element of the formation which emits delayed gamma rays when activated with neutrons. The formation is activation logged before and after such fracturing. The difference in the logs is a measure of the extent of travel of the fracturing fluid or extent of deposition of the proppant within the fractured formation.

Method and apparatus for treating long formation intervals

Abstract: A method and apparatus for treating a long interval within a wellbore wherein a treatment fluid is delivered to selected levels within the interval by blocking flow to certain zones while allowing flow to others. A treatment tube extends substantially through the interval and is comprised of a perforated conduit which is open at its upper end and which has a plurality of openings spaced along its length. Each of the openings have a valve seat within said conduit at its entrance which is adapted to receive a valve means to seal and block flow through that opening. In operation, a treatment fluid is flowed through the treatment tube and out the openings into different levels within said wellbore. At desired intervals, valve means are introduced into the treatment fluid and are carried into the treatment tube to seat at a respective opening to thereby block flow through that opening while allowing continued flow through others

Method and arrangement of apparatus for hydrogenating hydrocarbons

Abstract: A CHD reactor is modified to include a feed nozzle arrangement which hydrogen-saturates the charged liquid before distribution across the fixed catalyst bed by a pair of gas/liquid distributor trays. Product is recovered from the catalyst bed through an apparatus arrangement comprising Glitsch grid to maintain low pressure drop in the system.
