Diverter Procedure While Drilling Fixed

Annular Bop Diverter

1 Where shallow casing strings or conductor pipe are set, fracture gradients will be low. It may be impossible to close the BOP on a shallow gas kick without breaking down the formation at the shoe. If a shallow gas kick is taken while drilling top hole then the kick should be diverted. Drilling shallow sand too fast can result in large volumes of gas cut mud in the annulus and cause the well to flow, also fast drilling can load up the annulus increasing the mud density leading to lost...

Mud Gas Separator Poor Boy Degasser

Poor Boy Degasser

The height and diameter of an atmospheric separator are critical dimensions which affect the volume of gas and fluid the separator can efficiently handle. As the mud and gas mixture enters the separator, the operating pressure is atmospheric plus pressure due to friction in the gas vent line. The vertical distance for the inlet to the static fluid level allows time for additional gas break-out and provides an allowance for the fluid to rise somewhat during the operation to overcome friction...

Subsea Bop Control Systems

Subsea Hydraulic Power Unit

As the indirect hydraulic control system is the most common system in use on semi- submersible rigs, the examination focuses exclusively on this system. Therefore, it is necessary to be conversant with this type of control. In particular, the examination 1 Position of equipment in the control system. You should be familiar with the equipment shown in Figure 50 and be able to located specific items by name. You should also be able to determine where individual items are located such as SPM...
