Azimuthal deep resistivity sensor maps formation layers: Geosteering tool guides horizontal wells through the reservoir

摘要

When Halliburton introduced the InSite ADR azimuthal deep resistivity sensor in 2008, oil and gas operators were increasingly focused on recovering reserves from complex reservoir structures. With characteristics such as relatively thin target zones, complex fault-block structures, steeply dipping beds, pinch-outs, and lenses, these reservoirs require accurate positioning of wells within tight targets. The InSite ADR sensor offers control in the guidance of horizontal wells through the reservoir by measuring the resistivity of the formations around the tool. The technology won the formation evaluation category of Hart Energy's 2008 Meritorious Awards for Engineering Innovation.
