Drilling new wells in search of oil and gas can be an ultimate grind for the wildcatters.

The project requires extensive planning, demands hours-long sessions of continuous boring and entails the deployment of some of the mostrobust and heavy-duty equipment and tools known to mankind.

No one said unearthing black gold comes easy—ever; it makes you muddy, and labours you down to bare cash bones.

One particular aspect of well drilling that professionals find extremely challenging is maintaining the constant circulation of drilling fluid inside the well.

This drilling fluid is needed for:

  • Cooling and lubricating the drill bit
  • Transporting cuttings (rock fragments) to the surface
  • Preventing the wellbore from caving in

While in the past, engineers have used conventional centrifugal pumps to accomplish this task, the solution has never been a satisfactory one, since these pumps simply aren’t equipped with the ability to hold the rigors of the slurry mud.

However, thanks to recent advancements in the oilfield instrumentation technology, engineers now have oilfield-exclusive trash pumps, which are helping them make the light work of their notoriously-greasy endeavors.

For many, trash pump is a device that’s used in dewatering applications, specifically in municipal or industrial settings. Essentially a centrifugal pump but with more power, deeper impeller vanes and larger discharge openings, it does its job pretty well.

Now the device is making—big time—into well drilling settings.

Today, more and more companies are using trash pumps for recirculating and reusing drilling mud for their on-ground oil exploratory projects.

Typically made of 30 percent chrome iron, these pumps provide optimum wear resistance to handle solid particles of varying sizes expertly. Some oilfield-exclusive trash pumps can even pump fluids of solid concentrations as high as 70 percent of their weight.

The base of the drilling mud used with these pumps can either be brine or freshwater.

Although, trash pumps are available in both diesel and gasoline configurations, most engineers prefer diesel trash pumps for drilling wells as these pumps offer higher efficiency.
