Oil-based flushed zone electromagnetic well logging system and method |
摘要 |
An electromagnetic energy well logging system and method includes transmitting electromagnetic energy substantially at a frequency of 4 MHz into an earth formation from a borehold traversing the earth formation. The true resistivity of an oil-based flushed zone of the earth formation is derived in accordance with the transmitted electromagnetic energy after it is passed through at least a portion of the oil-based flushed zone.
