Occidental Petroleum Corporation Production Engineer Interview Questions and Answers

Saturation can be calculated using various methods depending on the context.

• In chemistry, saturation can be calculated using the solubility product constant.

• In physics, saturation can be calculated using the maximum magnetic field a material can withstand.

• In electronics, saturation can be calculated using the maximum current a transistor can handle.

• In oil and gas production, saturation can be calculated using well logs

GR log is used to measure the natural gamma radiation emitted by the formation.

• GR log helps in identifying lithology and mineralogy of the formation.

• It is used to correlate between different wells and identify hydrocarbon zones.

• GR log is also used to detect radioactive minerals like uranium and thorium.

• It is an important tool in formation evaluation and well logging.

• GR log is measured in API units and can be affected b
