Well activation is one of the most important aspects in the oil and gas  industries and nitrogen gas is predominately used. The gas, being light,  is sent down the producing reservoir which will enhance the production  or improve the flow of crude oil. In addition to the methods used to  increase production there are several problems like sand production and  water production from the producing wells.

Sand production occurs  when the destabilizing stresses at the formation face exceed the  strength of the natural arching tendencies and/or grain-to-grain  cementation strength. Ideally, during oil production, the formation  should be porous, permeable and well consolidated through which  hydrocarbons can easily flow into the production wells. But sometimes,  especially during production from unconsolidated sandstone reservoirs,  the produced hydrocarbons may also carry large amounts of sand into the  well bore and sand entering production wells is one of the oldest  problems faced by oil companies and one of the toughest to solve. These  unconsolidated formations may not restrain grain movement, and produce  sand along with the fluids especially at high rates.

Water  production is also a problem that many reservoir or production engineers  face in day-to-day life. As engineers we should be able to decide  whether water control solutions should be applied or not. The excess  production of water is caused by the depletion of the reservoir and  simply sweeps away most of the oil that the reservoir can produce.

This  book gives an information how well activation using nitrogen is carried  out, and how sand control and water control issues can be resolved.
