This is the first part of a two-volume work which comes at a time when oil producers are taking a close look at the economy of oilfield operation and redesign of production technology to improve ultimate recovery. The very high cost, and risk, of the search for new oilfields demands the re-evaluation of production technology and reservoir engineering to improve the production characteristics of existing oilfields.It is the aim of this work that it will be instrumental in the improvement of the global enhancement of oil production and ultimate recovery. It is the outcome of extensive collaboration between experts in petroleum who have devoted their time to the lucid expression of the knowledge that they have acquired through experience in the evaluation and solution of field problems, and development of economic field processes. Oil production companies have been generous in their cooperation through assistance and encouragement to the authors and permission to publish data, designs and photographs.Together, the two books provide a detailed and comprehensive coverage of the subject. The physical and chemical properties of the fluids encountered by engineers in the field are clearly described. The properties, methods of separation, measurement, and transportation of these fluids (gases, condensate liquids derived from natural gas, crude oils and oilfield waters) are dealt with. Following a presentation of the fluids and their process technology, a series of chapters give a thorough discussion of every type of surface equipment that is encountered in the myriad aspects of oilfield operations, ranging from waterflooding to new enhanced oil recovery techniques. Included are all methods for pumping, water control, production logging and corrosion control. The coverage also extends to: well completion and work-over operations, methods for design and operation of underground gas storage, and a review of offshore technology.Surface Operations in Petroleum Production is therefore a comprehensive reference which will be invaluable for field production managers and engineers; as well as being an ideal text on production technology to complement the study of reservoir engineering.

This second volume of Surface Operations in Petroleum Production complements and amplifies Volume I which appeared in 1987 and covered several aspects of oilfield technology. This second volume presents a detailed theoretical and practical exposition of surface oilfield practices, including gas flow rate measurement, cementing, fracturing, acidizing, and gravel packing. In today''s era of specialization, these operations are generally left to service companies, denying field engineers and company managers direct detailed knowledge of the specific surface and subsurface operations. This book presents a comprehensive analysis which may be used by field engineers to analyze technical problems, specify the required surface and subsurface operations, and closely supervise the service company''s work and post-treatment operation of the well.Another subject which has great economic consequences in all oilfields is corrosion of equipment. The book presents a comprehensive analysis of the theory of corrosion in the oilfield and methods that have proved effective for the retardation, or elimination, of corrosion. Quality control of injection waters in then covered. Three more topics are addressed: the first is offshore technology which is presented with reference to onshore oilfield operations, making a lucid presentation for field engineers who have no practical knowledge of the subject. The second is pollution control - an area of oilfield management which has assumed widespread importance in recent years. The last topic covered is the subject of underground storage of gas and oil. Underground fuel storage and retrieval is an active area of oilfield production management that utilizes the technology presented in this entire treatise. Finally, the technology of testing petroleum products and sample experiments for junior and senior petroleum engineering students are presented.This two-volume comprehensive treatise on modern oilfield technology thus provides not only a complete reference for field managers, engineers, and technical consultants, but will also serve academic needs in advanced studies of petroleum production engineering.

This book may offer a cautionary tale in the age of Covid-19. The narratives we shape around disease in society are so often about politics, and the competing versions of leprosy eradication's story are no exception.In one telling, the extra-budgetary funding for anti-leprosy work came with unwarranted interference in the WHO programme, resulting in an over-hasty, acrimonious and ultimately unsuccessful elimination campaign. In another interpretation, a great work of twentieth-century disease control was accomplished, through extraordinary philanthropy, visionary courageousness, and wily and pragmatic diplomacy. In yet another, experienced, self-sacrificing anti-leprosy experts refused to abdicate their professional responsibilities to populist campaigns more concerned with statistics than people, which were risking patients' health with under-trialled drug therapies and irresponsibly entrusting medication to patients without supervision.None of these bureaucratic, triumphalist or elitist narratives exists independently of the others. None is without credit, and none is to the complete credit of all involved. These competing stories offer uncanny resonances in the ongoing politics of public health, which have only intensified since both the emergence of M. Leprae millennia ago, and the concerted campaign against it in the last seventy years. What could the 'stories of leprosy' tell us about our pandemic response?
