Loss of Circulation


Loss circulation occurs when fluid/mud flows into the formation fissures, fractures or caverns and fills these spaces instead of returning up the annulus.

Depending on the situation, circulation loss can cause problems ranging from losing money on drilling fluid, all the way to a complete well blowout, so it is vital to monitor and resolve circulation issues before they escalate.

Another consequence of loss circulation is dry drilling, where fluid is completely lost from the wellbore. The effects of dry drilling range from as minor as destroying a bit, to as serious as major damage to the wellbore.
