Since 2002 over 60 vertical deep drillings have been investigated. The engineering radar system is suitable for any engineering applications in horizontal, vertical or inclined boreholes. The operation in low conductive, non-magnetic media is essential for the success of a radar measurement. A ...
Surface casing vents divert natural gas migration along oil and gas boreholes to bypass groundwater, with the gas venting to the atmosphere. While this strategy is designed to protect groundwater, it constitutes a source of greenhouse gases to the atmosphere. In instances where gas leakage occurs...
This capability makes monitoring borehole stability throughout the entire drilling process possible, even wh... CL Dalton,Paulk, M.D.,GWJ Stevenson - 《Journal of Canadian Petroleum Technology》 被引量: 11发表: 2002年 A novel high pressure, high temperature vessel used to conduct long-term ...
Bitumen is recovered from an underground tar sands (oil sands) formation by an in-situ percolation process. After drilling a borehole to the bottom of the ... E Yildirim - US 被引量: 56发表: 1983年 Lithofacies and related hydrocarbon accumulations in Tertiary strata of the western and cent...
viscousfluid mixture that is used in oil andgasdrilling operations to carry rock cuttings to the surface and also to lubricate and cool the drill bit. The drilling mud, by hydrostatic pressure, also helps prevent the collapse of unstable strata into the borehole and the intrusion of water ...
