Identical Circulating Density (ECD) – The ECD will be higher if the strong substance builds, whether or not High Gravity Solid (HGS) or Low Gravity Solid (LGS). As you may know, over the top ECD will prompt development crack and a misfortune dissemination lost circulation.

Differential Sticking – The channel cake can be thick and tacky, if there are a great deal of low gravity solids in the penetrating mud. When there is thick mud cake, you will can possibly stall out across penetrable developments.

Pace of infiltration – High centralization of the strong substance will influence the general pace of entrance. As you most likely are aware, there are three strong substance added into the framework. The initial two substance are weighting material and synthetic compounds which we truly need them in the boring liquid. For this part, we can’t diminish their substance in the mud since they are fundamental to for mud properties. The last one is the drill strong that we can handle by mechanical techniques. Thusly, to ideal ROP, you need to control the measure of bored strong in the mud.

Flood/swab pressure – The exorbitant flood and swab pressures are come about because of the great measure of strong substance in the liquid framework.

At the penetrating site, boring mud engine disappointment downhole might be occurred occasionally. The inquiries that are typically raised are things like “How can I say whether the it fizzles down opening?” and “What signs will I see that this has occurred?” and so on Because of this, I might want to share my own experience in regards to the mud engine disappointment and its side effects.

The accompanying signs show that you might be confronted with downhole mud engine breakdown.

Successive Motor Stall – Motor slow down happens when the rotor of the mud engine has quit moving. Commonly, the engine slows down just with a high differential of pressing factor. Be that as it may, if the down opening hardware doesn’t proceed as typical, it will get slowed down with just barely of differential pressing factor. For example, a mud engine regularly bores at 400 psi differential pressing factor, however on the off chance that it is slowed down out with just 100 psi you can speculate the issue is with the engine.

Pressing factor vacillation while turning – As you most likely are aware, differential pressing factor it a set boundary while pivoting down, not founded on the load on piece (WOB). Pivoting with a decent mud engine will not make pressure variances, while a terrible mud engine will show vacillation in stand pipe pressing factor and you will most likely be unable to keep up consistent pressing factor.
