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 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：The first step in planning a well should be the gathering of all available data on past wells. In this respect it is important to be completely familiar with all sources of information, the availability of the sources, and the information normally associated with each source.

翻譯：If Colonel Drake, Uncle Billy smith , Anthony Lucas , and the untold thousands of other members of the fraternity of drilling pioneers were alive today , they would no doubt be fascinated and amazed by the proliferation of drilling tools and techniques that have been developed since those primitive days in Pennsylvania and Texas . Undoubltly , they would also be impress by the great numbers of drilling rigs at work today-------over two thousand in the USA alone.

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：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：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：An acidizing treatment for a sandstone formation normally will consist of sequentially injecting three fluids---a preflush, the hydrofluoric acid hydrochloric acid mixture, and an after flush. These fluids serve definite purposes.

翻譯：In addition to being useful as an exploration tool, subsurface maps are a necessary part of any reservoir engineering study; and petroleum engineers, as well as geologists, must be completely familiar with their construction and interpretation.

翻譯：There are two approaches to the problem of determining the fluid saturation within a reservoir rock. The direct approach is to measure, in the laboratory, the saturation of selected rock samples recovered from the parent formation. The indirect approach is to determine the fluid saturation by measuring some related physical property of the rock.
