The Mud tanks system consists of equipment on board that contributes to the storage, mixing, circulation and purification of drilling fluid. Drilling fluid is very expensive and large volumes are used in connection with drilling a well. It is therefore desirable to reuse drilling mud.
Mud Cleaning System
The mud tank system should remove cuttings that come up from the hole along with the drilling mud so that the cleaned mud can be returned to the well. If the mud does not have the proper properties in relation to the well, it can result in major damage to the well and the drilling equipment. After the cleaning process, the drilling mud is carefully checked to make sure that the cleaning system has done a satisfactory job.Continue reading “Mud Tanks System”
Water dilution and subsequent disposal of the excessive mud volume into drilling reserve pits were the simplest ways of dealing with inefficient solids control systems.Properties of all drilling muds tested are shown in Table 1. The only drilling mud used for the full-scale test was the non-dispersed spud mud with limited filtration control.Continue reading “Dewatering Process Efficiency and Effects”
Effective rotary steerable drilling systems overcome most of the problems with steerable motors by providing continuos pipe rotation while drilling. This is accomplished, with the tool reported on in this paper, with a non-rotating steerable sleeve containing three extendable pads that push against the borehole wall.Continue reading “Rotary Steerable Drilling Systems”
A step-change is needed in drilling process control, to enable consistently high performance, accurate pressure control and reduced risk of unwanted effects. Advances in process control have been made but risk reduction and optimization of the drilling process is still a major challenge.
