What is a scalping shaker?
The ”rig” shakers remained attached to the flowline to remove very large cuttings and gumbo. These were called scalping shakers. Even in places where gumbo might not be present, scalpers were used to prevent very large cuttings or large chunks of shale from damaging the API 200+ screens.
How does a shale shaker work?
The shale shaker separates the cuttings from the drilling fluid by running it through a vibrating screen, allowing the fluid to be pumped back into the well and reused. In addition to saving money, reusing drilling fluid means it doesn’t have to be disposed of, reducing regulatory and compliance costs.
What is gumbo in drilling?
1. n. [Drilling] A generic term for soft, sticky, swelling clay formations that are frequently encountered in surface holes offshore or in sedimentary basins onshore near seas. This clay fouls drilling tools and plugs piping, both severe problems for drilling crews.
What is G Force in shale shaker?
Most shaker baskets are vibrated with a 5-hp or smaller motor and produce 2–7 g’s of thrust to the vibrating basket. Conventional shale shakers usually produce a g factor of less than 3; fine-screen shale shakers usually provide a g factor of between 4 and 6. Some shale shakers can provide as much as 8 g’s.
What is shale shaker screens?
The shale shaker is the first stage of solids control equipment in drilling purification system, also known as key solids control equipment in drilling mud system.used for separating larger cuttings above 75 μm brought from the drilling well to leave the liquid with smaller particles into the tanks below, which will …
What is a gumbo box?
Gumbo boxes are the first step in effective solids control when large, sticky, hydrated clays (gumbo) and other troublesome solids are encountered during drilling. Gumbo boxes use a motorized chain conveyor to remove problematic solids before they reach the shale shakers.
What is shaker in oil and gas?
shale shaker in the Oil and Gas Industry
A shale shaker is a moving screen which removes cuttings from the mud so they can be disposed of. A shale shaker is a vibrating screen or sieve that strains cuttings out of the mud before the mud is pumped back down into the borehole.
How does a Desander work?
Desanders are installed downstream from the shale shaker and degasser. The desander removes sand-sized particles and larger drilled solids which have passed through the shaker screen and discards them along with some liquid. The partially-clean drilling fluid is discharged into the next compartment downstream.
How can I improve my gumbo?
Bonus Tips and Tricks
- Grill meats or roast garlic on the grill before adding to the pot for a good rustic flavor.
- When using wild meats cut the game taste with beer or white wine.
- Add crawfish tails or oysters.
- Add crabmeat if you don’t want to peel the crabs.
- Food process veggies to hide them in the gumbo.
What is in Louisiana gumbo mix?

What is a desander in oil and gas?
1. n. [Drilling] A hydrocyclone device that removes large drill solids from the whole mud system. The desander should be located downstream of the shale shakers and degassers, but before the desilters or mud cleaners.
How does a desander cone work?
How to service DeSander & DeSilter in Offshore Rig – YouTube
Is gumbo better the longer it cooks?
Go Low and Slow
Slow cooking allows all of the flavors to marry together and keeps the gumbo from burning or over-reducing. Some people say that gumbo tastes better the longer it sits, and even recommend making it a day in advance.
Should gumbo be thick or soupy?
The one thing that really defines it, though, is the way it is thickened. Gumbo is much denser than a simple soup; the broth has a thick, almost viscous consistency. And that characteristic is most commonly created by making a roux, cooking flour and oil together until they thicken and darken.
Is gumbo base the same as Roux?
A Gumbo Roux (pronounced ROO) also known as Gumbo Base is a dark brown cooked mixture of white flour and oil which is used to thicken Cajun and Creole dishes like a Gumbo. Pin It!
What bread goes good with gumbo?
Cornbread
A southern staple, this side dish complements the soupy and zesty gumbo. The dense, dry texture of the bread helps absorb all the liquid from the gumbo and make the bread more delicious.
What is the purpose of desander?
Desanders are primarily used to remove the high volumes of solids associated with extremely fast drilling of a large diameter hole, especially when a fine screen shaker is not available. Desanders are installed downstream from the shale shaker and degasser.
What does a hydrocyclone do?
A hydrocyclone is a high-throughput gravity separation device used for separating slurry particles based on particle weight. For example, particles of similar size but different specific gravity, or particles of different size but identical specific gravity.
How does a desander work?
What is a desander in drilling?
Desanders and desilters are solid control equipment with a set of hydrocyclones that separate sand and silt from the drilling fluids in drilling rigs. Desanders are installed on top of the mud tank following the shale shaker and the degasser, but before the desilter.
What makes gumbo spoil?
An insulated cooler stays cold longer than a plastic one. Once the ice packs have melted, spoilage can occur, making it important to eat the gumbo right away or get it into a refrigerator or freezer. Another option is to freeze the gumbo prior to transporting it, which gives you a longer period before spoilage begins.
Why does my gumbo taste bitter?
“The reason is, once butter gets to a certain temp the fat and solids separate, this will occur before you get the roux to the color you want it, then the solids will begin to burn,” says Harden. This will leave your gumbo with a burnt bitter flavor, so instead opt for vegetable oil or even lard as the roux’s fat.
How do I give my gumbo more flavor?
What are the 3 types of roux?
