THE EARTH PIT UNIT
The pit unit allow the sand hand to discharge into the earth pit. This eliminates the expense of hauling off water and sand, disposal fees, tank rental and delivery fees. The sand hand ensures big savings on high sand producing wells. The pit unit is safely rigged up from behind the berm and inside the handrails eliminating the risk of falling in the pit. Each component of these units can be feasibly picked up by one person and assembled by hand. The berm deck is placed on the berm by a chain hoist on a monorail trailer, no lifting necessary. Anchors, blocks, and restraints are needed to secure the pit unit under high pressure. A bypass is rigged up for times when sand weights aren’t needed on every dump.
DESIGNED BY FLOWBACK FOR FLOWBACK
The sand hand was designed for flowback and perfected in the field on well tests under just about every flow variation known.
DIVERSE
There are many features and attachments that make the sand hand work so well and diversified to fit any application.
ADAPTABILITY
The steps are individually detachable to meet any size half tank and a berm deck with steps and working deck that accommodate any size berm.
FAST AND ACCURATE
Excess water is removed by tipping the sock to a 90° angel without losing sand. The sock also locks into the dump position, allowing the sock to be jerked with the cable removing any residual sand stuck in the sock. This ensures a faster more accurate sand weight.
SEPERATION
It is cyclonic, separating the gas from the slurry allowing the gas to discharge through a discharge pipe. This minimizes the sock ripping or blowing off into the half tank. As well as reducing the potential exposure of hazardous gases.
ROBUST WEIGHING SYSTEM
The scales are custom made for simplicity: lbs only, durability: strong, weighs up to 660 lbs and weather resistant, stays running with a solar powered digital scale monitor in an enclosed explosion proof box for class 1 Division 2 and intrinsically safe load cell and circuit for class 1 Division 1.
SAND DOESN'T BRIDGE
The socks are tapered so the sand does not bridge, instead it slides right out.
OPTIMIZED
We use a 4.5-gallon sock for High volume sand. The big socks are shorter, allowing 11 more inches for sand to accumulate under the sand hand. This equates to tons more sand before needing a vac truck.
SAFE
The sand hand is considered open ended but for added assurance there is a pop off that redirects the slurry back into the 1/2 tank if it was to ever sand off. (We have never had a sand hand sand off to date.)
EASE
The sock is mounted on a carriage with a pulley system allowing the sock to be rotated and dumped with ease. The operator is able to weigh and dump up to 76 lbs of sand with one finger.
CONVIENENT
There is a working deck with plenty of room to rig up and operate the sand hand
PROMOTES PROFESSIONALISM
Employees are more apt to dump traps correctly if they are not overwhelmed by volume, worn out from hard labor or fear of hard labor.
REDUCES WASTE
The sand hand changes the dynamics of dumping an SKO there is more of a sense of urgency to close the adjustable choke when the sock starts to overflow reducing the amount of water flushed into the 1/2 tank and less sand washed out of the sock, there is also a less chance of flushing oil and gas reducing product waste, disposal, and trucking expense.
SAND BUSTER
There is a sand buster that breaks up the sand as it dumps out of the sock, eliminating fluid from splashing back on to the operator.
WHY IS THE SAND HAND A NECESSARY PIECE OF OILFIELD EQUIPMENT?
ABOUT HOW many sand hands are needed on a location?
Normally one sand hand per 3 well pad or 2 on a 4 well pad, because of the length of the dump line. When there is a lot of sand being produced per well 2 sand hands should be used in unison with a plug valve between the 2 to even the flow between them allowing a higher volume of sand to be captured without having to dump a second time to empty the SKO.
