10 Things to Consider When Buying Derrick Hyperpool PMD Screen
How to Choose the Best Shale Shaker for Product Quality
Shale shaker is used to separate drilling cuttings for first phase cleaning in a whole solids control system. Shale shaker are components of solids control equipment used in many industries, such as oil and gas drilling, coal bed methane( CBM ), horizontal directional drilling ( HDD ), diamond drilling, water drilling , etc . So, do you want to know how to choose the best shale shaker? Now, let&#;s go!

So, you&#;ve got some shale to shake, huh? Well, whether you work in the oil and gas industry or are just a regular shaker enthusiast, you know that choosing the right shale shaker is crucial to achieving top-notch product quality. With so many options, it can be a little overwhelming. Have no fear, dear reader, because I&#;m here to help you navigate the rough waters of shale shaker selection.
How to choose the shale shaker
First, let&#;s talk about what an excellent vibrating screen is. You need to look for a vibrating screen with a high processing capacity so that it can handle the volume of shale you are processing. And don&#;t forget about vibration intensity &#; you want a vibrator that can really shake things to separate solids from liquids.
But don&#;t worry, that&#;s not all! Product quality also depends on the materials used to construct the vibrating screen. Choose a product that is made from high-quality raw materials and undergoes rigorous heat treatment. After all, you want your shaker to be able to withstand the heat of the action, right?
Let&#;s talk about maintenance.
No one wants to deal with tons of spare parts and sky-high maintenance costs. Look for vibrating screens that require few spare parts and little maintenance. Trust me, your future self will thank you for it.
When choosing a shaker, you want to make sure you make the right decision. After all, no one wants a rickety shaker that can&#;t withstand heat. So when you&#;re looking for the perfect shaker, keep these tips in mind. Whether you shake shale for work or pleasure, choosing a shaker with high handling capacity, strong vibration intensity, quality materials, and low maintenance costs will ensure top-notch product quality. Happy shaking!
HDD Equipment Spotlight: Shakers and Screen Technology
Conventional mud systems owned by Directional Service South of Bossier City, Louisiana, were struggling to recycle the drilling mud effectively.
Each horizontal directional drilling (HDD) rig &#; two 440,000-lb rigs and one 625,000-lb rig, typically circulating 375 gpm and drilling up to 44-in. holes &#; was paired with a mud recycling system having four conventional shakers running flat mesh screens. DSS also utilized a secondary mud system with two additional conventional shakers for further polishing of the primary mud system overflow and to perform mud mixing.
The drills were required to stop frequently allowing sufficient time for the mud system to process the mud returns from downhole. Additionally, mud pump rebuilds were required every few weeks, with costs as high as $10,000 per month per pump.

Directional Service South&#;s objectives included implementing a single high-performance system (replacing the six shaker system presently in use) that could effectively mix and recycle mud at rates up to 375 gpm, assuring the mud system was no longer the bottleneck of the drilling operation and reducing the frequency of rebuilding their mud pumps.

After spending time at Derrick Equipment Co.&#;s Houston test tank facility observing various Derrick shaker demonstrations, Directional Service South decided to upgrade one of its two shaker mud systems with Derrick Hyperpool shakers.
Drilling or tunneling performance is directly related to the overall cleaning ability of the separation equipment. Drilled solids remaining in the slurry have numerous adverse effects on the overall operation, significantly reducing its profitability. Consequently, selecting the proper separation equipment for your fleet is just as critical as choosing the correct drill or tunnel boring machine.
Derrick has offered premium slurry separation and desanding equipment to the worldwide microtunneling, horizontal directional drilling, large diameter tunneling, slurry wall/foundation drilling, water well drilling, and other civil construction industries for nearly 30 years. Throughout this time, Derrick has remained dedicated to complete in-house manufacturing of every machine, screen panel, and tank system. Each unit is created and assembled at Derrick&#;s Buffalo, New York headquarters facility.
One Hyperpool shaker would handle primary screening, while the second unit, fitted with a 10-cone inline desilter package, would handle finer particle separation. Both shakers would utilize Derrick Pyramid screens that fully comply with API RP13C standards.
Immediate results were seen after Directional Service South placed its first upgraded mud system into service in December in the Houston area.
RELATED: Good Practices in Solids Control
According to Directional Service South co-owner Jake Gautreaux, the Derrick Hyperpool shakers have exceeded expectations by providing the following benefits:
Reduced Non-Productive Time:
- The two Hyperpool shakers effectively handled the mud returns at 375 gpm, eliminating the frequent drill rig hold-ups due to inefficient mud processing.
- Frequency of mud pump rebuilds has been reduced dramatically. Typical rebuild intervals for high pressure pumps has improved from every few weeks to six months or better. This improved service life is due largely to improved solids removal efficiencies from the Hyperpool shakers and Pyramid screens, and maintaining a lower sand content, which now ranges from trace amounts to 1/4 percent.
- DSS estimates pump repair cost savings can be as much as $50,000 per pump over a six-month period.
Major reduction in screen consumption:
- Derrick&#;s patented Pyramid Screens improved processing capacity and provided significantly longer screen life
- The initial screen requirement has been reduced from 24 screens to eight screens. For a single crossing, which can exceed 8,000 ft in length, no more than eight screen panel changes have been required.
- Directional Service South estimates a reduction in screen costs in excess of 40 percent.
Increased HSE benefits:
- Greatly reduced shaker noise output increases rig crew safety.
- Unlike the previous conventional system that used wedges to hold down much heavier pre-tensioned panels, the far more user-friendly Derrick unique spring compression system encourages rig crews to change screens when needed. Together with lightweight screen panels, which allow for one-minute screen changes, this system has yielded significant HSE benefits.
In addition to the performance improvement, Gautreaux found that working with Derrick has been a &#;pleasure.&#; He has also found that the technical recommendations have been spot on in terms of the various upgrades to their mud systems, screen panel selection, and field troubleshooting.
The Derrick Hyperpool shakers and innovative PMD screen technology have resulted in a much more cost-effective drilling program by drastically reducing non-productive time and operating costs and allowing for increased downhole production.
