Oil Muds And Its Troubleshooting

An oil base fluid can be defined as a drilling fluid which has oil as its continuous or external phase and the water, if present, is the dispersed or internal phase. The solids in an oil base fluid are oil wet, all additives are oil dispersible and the filtrate of the mud is oil. The water, if present, is emulsified in the oil phase.

TYPE OF OIL-BASED MUDS

Oil-based mud is a drilling fluid used in drilling engineering. It is composed of oil as the continuous phase and water as the dispersed phase in conjunction with emulsifiers, wetting agents and gellants. The oil base can be diesel, kerosene, fueloil, selected crude oil or mineral oil. –wiki

TYPES OF DRILLING MUDS

Drilling fluids are generally categorized as “water-based” or “oil-based”, and as “weighted” or “unweighted” muds.

WELL CONTROL OPERATIONS

Establishing Regular Drilling – Flow Chart

FLOW CHART FOR SIMULATOR DRILLING OPERATION

Establishing a Well Control Situation- Flow Chart

Circulating Out a Kick (to kill the well)

Set the stroke counter on both Drillers Console and Remote Choke console to zero.
Obtain the Kill Sheet with SIDPP & SICP and all calculated parameters.
Also obtain Kill Mud Weight and Maximum Allowable Casing Pressure.
Bring up pump at slow circulating rate (0-30 SPM) while maintaining casing pressure constant at the SICP using the remote choke control, continue till at 30 SPM or slow pump rate.
Follow the pressure decline on the Kill Sheet by opening and closing the choke at the remote choke console till final circulating pressure is reached, as seen on Drill Pipe Pressure gauge.

At this point, the well should be killed. Flow check reveals DPP = 0, CSGP=0.
