NEW MOBIL TECHNOLOGY LICENSED BY STATOIL

 NEW MOBIL TECHNOLOGY LICENSED BY STATOIL
 FAIRFAX, Va., Aug. 19 /PRNewswire/ -- New technology that could


save oil producing companies millions of dollars has been licensed to Statoil, the Norwegian state oil company, Mobil Corporation (NYSE: MOB) said today.
 Statoil is the first licensee of Mobil's new ALLPAK gravel packing technology. This new technology provides multiple, alternate flow paths for the gravel slurry that forms a filter to prevent sand from being produced with the oil. Statoil has used ALLPAK gravel packing on two producing wells in the Norwegian North Sea and plans to use it in numerous wells over the next several years. Mobil currently is using the technology in 14 producing zones in the Gulf of Mexico.
 Some producing wells require that gravel be packed in the producing interval to prevent formation sand from entering the well bore. The amount of gravel needed is calculated for each well based on the length of the interval to be packed, the type of well, and other factors.
 With existing technology, the quantity of gravel that is packed can, in many cases, be only about 60 percent to 70 percent of the required amount. This incomplete packing allows sand from the producing formations to enter the well, which can block the flow of oil or damage mechanical equipment in the well and at the surface. Both situations lead to costly corrective procedures and can curtail the total amount of oil produced. ALLPAK gravel packing allows 100 percent of the required quantity of gravel to be packed in the well. Its use saves time and operating costs during and after gravel pack installation, increases production rates and extends the productive life of the well.
 This new technology incorporates several perforated rectangular metal tubes that are welded to conventional gravel pack screens and placed in the well bore. Using conventional technology, when gravel being placed in the well accumulates at any point along the interval being packed, the flow of the gravel slurry is blocked, leaving voids in the packed interval. With ALLPAK technology, the perforated tubes provide alternate flow paths around the blockage permitting the interval that is further down the hole to be packed. This technology can also be used to pack several producing intervals simultaneously. Other gravel packing methods require that each interval be packed individually, which greatly adds to installation costs that can exceed $1 million.
 Baker Sand Control, a Mobil authorized supplier, has installed many of the ALLPAK gravel packs in use today.
 ALLPAK technology was developed by Mobil Research and Development Corporation, a unit of Mobil Corporation. Information on licensing ALLPAK technology can be obtained from Mobil Technology Sales and Licensing at 609-737-5481 or (fax) 609-737-5640.
