翻譯：Meanahile ,steel pipes that would carry the oil were being developed . These were the first oil pipelines which take the advantage of the fact the oil is a liqnid. The ideas of a pipeline were not new , water has been transported through pipes for handreds of year ,The oil pipeline were not accepted without a struggle, hower.
翻譯：The fluids of a petroleum reservoir are generally gas, oil, and water in varying proportions. Each phase can differ widely in composition and properties. Gas and oil, either as separate fluids or in mixtures, change their state or phase as reservoir pressure changes.
翻譯：Since the volume factors and the solution gas-oil ratio are determined from laboratory measurements on samples of reservoir fluid at reservoir temperature and various pressures, these parameters are effective substitutes for detailed phase equilibrium data in most production calculations. However, these parameters are unknown at the time that exploration well tests are run, and hence they are estimated from correlation charts.
翻譯：This chapter deals with the fundamental properties of reservoir rocks. The properties discussed are (1) porosity - a measure of the void space in a rock; (2) Permeability - a measure of the fluid transmissivity of a rock; and (3) fluid saturation - a measure of the gross void space occupied by a fluid. These properties constitute a set of fundamental parameters by which the rock may be described quantitatively.
翻譯：The transportation of oil has also led to the spectacular development of gait ships ,the largest ships that ever sailed the oceans of the world .in the last few years ,since it has been necessary to ship oil from middle East-one of the largest oil producing regions-around the cap of Good Hope in south Africa these tanks has grown to almost unblievable proportions.
翻譯：The primary limitations for gas lift operations are the lack of formation gas of an outside source of gas, wide well spacing, and available space for compressors on off-shore plat forms. Generally, gas lift is not applicable to single-well installations and widely spaced wells that are not suited for a centrally located power system.
翻譯：A major oil company usually initiates the sequence of events that leads to the drilling of oil and gas wells in foreign fields, but independent oil operators pay for most of the wells in the United States. In fact, about 80% of all wells drilled in the U.S. today are financed by independents.
翻譯：A porous medium has a permeability of one darcy when a single phase fluid of one centipoise viscosity that completely fills the voids of the medium, will flow through it under conditions of viscous flow at a rate of one cubic centimeter per second per square centimeter cross sectional area under a pressure or equivalent hydraulic gradient of one atmosphere per centimeter.
翻譯：The need for a greater understanding of the pumping process and for the ability to engineer pump installations to a close degree of tolerance is being accentuated by the trend to pump from greater and greater depths . Problems are relatively minor when the pump is at 10,000 ft.
翻譯：Land maps are essential in establishing control wells and provide fundamental orientation. As Fig.2 illustrates, land maps which are readily available within most companies as well as readily available commercially, provide offset operators, total depth, formation tops and development dates. The land map is essential in establishing orientation and control.
