Abstract
The use of vibration to improve oil recovery has long been investigated. The
background for this novel technology is reviewed along with the project rationalizations,
designs considerations, and measurements performed in advance of a downhole
vibration stimulation field test. This field demonstration will pilot test
the potential of downhole vibration to enhance oil recovery from a shallow
oilfield in Osage County, Oklahoma. The project is supported by the Department
of Energy (DOE), Seismic Recovery LLC, Phillips Petroleum Co., and Grand Resources,
Inc. Recent literature has reported successful vibration stimulation in shallow
reservoirs with high water oil ratios (WOR). Osage County has, like many areas
of the United States, numerous old fields under waterflood, with many wells
producing marginal oil with substantial water production.
