Question 3246 Deck General

The correct answer is B) high formation pressure. Large quantities of gas in the shale shaker area can indicate high formation pressure. High formation pressure means the pressure within the geological formation being drilled is significantly greater than expected, which can lead to an influx of gas or other fluids into the wellbore. This is a potentially dangerous situation that requires immediate action to control the well. The other answer choices are incorrect. A break in the drill string (A) or riser system (D) would not necessarily indicate high formation pressure. Low formation pressure (C) would not cause large gas influxes at the surface.
