简答题 翻译：The permeability of a porous medium may be determined from samples extracted from the formation or by in-place testing.

问答题翻译：The main function of a rotary rig is to drill a hole, or as it is known in the industry, to make hole.

问答题翻译：Finally, it should be noted that the effective compressibility of an oil-gas mixture below its bubble point pressure is large, since much of the volume decrease with pressure increase is associated with the change in phase of some the gas to a liquid.

问答题翻译：The gas formation volume factor Bg is the volume measured at reservoir conditions that corresponds to a unit volume of gas at standard conditions. Thus, Bg<1.

问答题翻译：These reservoirs contains oil at the bubble-point pressure at the gas-oil contact atdiscovery but are increasing toward the aquifer.

问答题翻译：As could be expected, the field of oil exploration has attracted the talents of many individuals who propose to find oil with numerous other witching devices.
