Reamers are used to enlarge a wellbore. It is necessary when a section of a whole is not drilled as wide as it should have been on the outset.
This can occur when a bit has been worn down from its original size, but might not be discovered until the bit is tripped out of the hole, and some undergauge hole has been drilled. Also, plastic formations may slowly flow into the wellbore over time, requiring the reaming operation to maintain the original hole size.

Keep Learning! Keep Growing!

Check this info out. Good info right here.
________
Just like race cars, drillers can measure their efficiency and understanding of the formations being drilled through the speed at which the hole is deepened.
__________
This is called the Rate of Penetration (ROP). Sometimes for large oil and gas fields an operator may employ the services of more than one drilling company to drill wells in an oilfield at the same time.
___________
The operator then compares the efficiency of the two companies by checking the ROP of the two companies at the end of a given period.
__________
ROP is something you should not leave to chance, if something can be controlled, by all means go on ahead and control it.
__________
Firstly, check your weight on bit and rotary speed (the speed at which the Kelly is rotated). A perfect combination of the two can work magic and this perfect combination can be obtained using trial and error. Gradually, change these parameters until you arrive at the perfect combination for a given formation.
___________
Also check your drilling fluid properties and make sure you are optimising the flow rate and viscosity of the drilling fluid. If your cuttings are not being properly carried out of the hole, you end up grinding the same cuttings and risk damaging the drill bit.
_____________
These are just a few rule of thumb tips. Efficiency matters especially in an era of low oil prices such as this.
_____________
Remember, don't sacrifice speed for the safety of the drill bit. It will be useless to drill too fast only to damage the drill bit and have to carry out tripping to change the bottom hole assembly (BHA). Optimisation is better than maximisation.

Essa dica é ideal para desentupir ralos da pia da cozinha e do banheiro. Coloque no ralo uma xícara de bicarbonato de sódio e depois acrescente duas xícaras de vinagre branco de álcool. Quando a mistura não estiver mais efervescente, despeje água fervente e evite abrir a torneira por cerca de 30 minutos.
