Well control refers to the techniques and procedures used to manage the pressure in a well during drilling operations. It is essential to prevent unexpected pressure surges, known as kicks, which can lead to blowouts—dangerous situations where oil or gas erupts uncontrollably from the well. Effective well control involves monitoring the mud weight, using blowout preventers (BOPs), and implementing proper drilling practices. These measures help maintain the balance between the pressure in the well and the surrounding formations, ensuring the safety of personnel and the environment while drilling for oil and gas.
