🔍 Key Concepts

• Shale shaker location and purpose in the drilling circulation system • What happens at surface equipment when formation fluids (like gas) enter the mud returns • Relationship between formation pressure and influx of gas into the mud system

💭 Think About

• Trace the path of drilling mud from the bit, up the annulus, through the riser, and into the shale shakers—where would gas that enters the well first become visible? • Ask yourself: would large quantities of gas at the shale shaker be more consistent with formation fluids entering the well, or with the well being underbalanced or overbalanced? • Consider which option describes a situation where the pressure in the formation compared to the mud hydrostatic pressure would cause gas to flow into the wellbore.

✅ Before You Answer

• Make sure you know that shale shakers are on the return line where mud comes back from the well to the rig. • Check whether low or high formation pressure is more likely to cause formation gas to enter the wellbore and show up at the surface equipment. • Verify that a mechanical break (riser or drill string) would more likely show as loss of mud or other symptoms, not just gas at the shale shaker.
