Oil Search PNG provided the following requirements for a large Air Mover. The SAM 210 was the solution.

 Oil Search requirements

The first application is to install a device (e.g. venturi) in an approximatley 8.5" ID steel pipe (blooie line) up to approximately 200 feet in length for carrying stiff foam (see attached photos) containing rock sediments/sand to a disposal area next to an oil/gas drilling rig working at approximately 3000 ft elevation above sea level in Papua New Guinea.  The foam is pumped/created using from 700 to 1200cfm air volume.  The foam is pumped down 5.5" OD drill pipe at 100 to 200psi and returns to the surface outside the drill pipe carrying the drilled cuttings.  The foam reaches the surface in the annulus between the outside of the 5.5" diameter drill pipe and the inside of a 30" OD x 28" ID steel riser, which is open to the atmosphere at the top.  The 8.5" ID pipe is planned to be ported into the 28" ID riser approximately 6 feet below the top end of the 28" ID riser.   The steel pipe is approximately horizontal, with very little drop angle. 

 

The sediments in the foam vary in size, but most would be sand size or smaller, but perhaps 5% of the sediments could be up to an inch in diameter.  Even larger cuttings may occassionally appear, but since they are rare, we feel we can ignore them for the moment and deal with them later if they indeed produce any problems.  The foam is enviromentally approved and there are no hydrocarbons of any kind in the foam returns from the well.  From a material balance stand-point,  the foam would contain on average 0.2 lbs rock sediment (~2.65sg) per std cu ft of air/foam, but at times the concentration could be orders of magnitude higher or lower."
