Description / back cover text:
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.

Mohammed Ismail Iqbal is currently working as a faculty member at University of Technology and Applied Sciences in Oman and has approximately 11 years of experience nationally and internationally in both teaching and academia. He is pursuing a PhD from Lincoln University College in Malaysia, and has finished a Master's in Oil and Gas Engineering from University of Salford, United Kingdom, an MBA in Oil and Gas Management from Petroleum University, and a Bachelors in Mechanical Engineering from Osmania University.Mr Iqbal has strong corporate relations and industry links, and has designed courses for UVM (Mexico), providing training to big IT giants like ITC Infotech, L&T IES, CAIRN, HCL, PETROSERV, BAPEX, setting up a drilling rig on the UPES campus, which is the first university in India. He has expertise in quality, accreditation, institutional planning (strategic planning, operational planning), quality assessment and experience in launching new programs in digital transformation age of Industry 4.0.His research interests are production optimization techniques using software like PIPESIM, enhancing recovery well productivity using well testing software like PANSYS, kappa and reservoir simulation using software named RFD, drilling optimization, and development of new chemical for sand control treatment, to name a few. He has published research papers in Elsevier, Scopus Journal, and peer reviewed journals in the research area mentioned above nationally and internationally, and also holds copyright for a research idea (risk assessment) and very recently filed a patent on classroom monitoring during social distancing.
