The "Sandtrap" downhole desander separates abrasive solids from production fluids before they enter a downhole pump. It installs simply on tubing below any type of downhole pump. Centrifugal action separates solid particles, which collect in extended lengths of mud anchor or rathole, extending pump life. The desander has no moving parts, is steel construction, and has a long life. It is available in standard models for different flow rates or in combination gas anchor and desander models.
Any type of pipeline pigging requires extensive planning, and professional assistance for either the pig manufacturers or a qualified pipeline cleaning service company

Using Downhole Jet pump with DST ApplicationsTaha Metwally
In this Article we can use downhole jet pumps during drill stem testing (DST) for production. Downhole jet pump used in reverse flow circulation. the best way for solids and abrasives handling. More economic way in testing phase either long term production and field profitability.
CSD is a stationary dredger equipped with a cutter device (cutter head) which excavate the soil before it is sucked up by the flow of the dredge pump(s).
This type of dredger is capable to dredge all kind of material and is accurate due to their movement around the spud. The spoil is mostly hydraulically transported via pipeline, but some dredgers do have barge-loading facilities as well.
The pipe sprayer consists of two air motors. One drives the body around the
central axis and the second drives the cup. The cup motor is set at an angle
into the body, thus as the cup revolves and body rotates a wobble motion is
set up generating a spray pattern inside the pipe. This wobble-
head action produces a reciprocating
fan pattern which enables coating to reach
the back edges formed by pit etc., in corroded
pipes. This avoids having to go through
the pipe in two directions allowing one coat
application.
The Grundfos DW pumps form part of a complete range of wastewater and sewage
handling products. Like all Grundfos products the DW pump series offer unique cus-
tomer benefits, making them the natural choice for any job where raw water needs to
be pumped - whether from construction sites, mining pits, excavations, or flooded base-
ments, etc.

Figure 1 Illustrates the flow path of produced fluids
through the desander sub. Fluid enters the tubing
through the inlet slots. The fluid must flow down through
a spiral to enter the orifice tube and flow upward to the
pump. Centrifugal action, created by the fluids flowing
through the spiral, pushes solids away from the vortex
flow of the orifice tube. Solids settle into the mud anchor
or rathole. The clean fluid flows upward through the
orifice tube to the pump.

3. DESCRIPTION
The Sandtrap Downhole Desander is run in the tubing below a downhole pump. Production fluids enter the
Desander Sub through its inlet slots. Centrifugal action created within the Desander sub separates solids such as
sand, scale, and iron sulfide from the fluids. The solid particles settle by gravity into the bull-plugged mud anchor
joints or the rathole.
For most reciprocating rod pump applications, the Desander Sub is substituted for a perforated nipple commonly
run below a seating nipple. Instead of running one joint of mud anchor, as many joints as possible should be run
below the Desander Sub. The mud anchor joints must have a bull-plug or a Dump Valve device on the lower end.
A Dump Valve allows the solids within the mud anchor to dump into the rathole on each downstroke of the pump.
The Desander Sub may be elongated in order to perform as a “poor boy” gas anchor.
When using the Downhole Desander below an electrical submersible pump (ESP), an ESP Packer is required.
This system diverts all production fluids into the Desander sub, back into the casing, past the motor for cooling,
and into the pump intake. Solids are collected in extended lengths of bull-plugged mud anchor.
The Downhole Desander may also be used below progressive cavity type pumps. The Desander Sub is run
on the lower end of the pump. As many joints of bull-plugged mud anchor as possible should be run below the
Desander Sub to serve as a sand trap.
Because no two wells are the same, The Cavins Corporation produces several models of the Desander. Please
consult the chart below and contact our sales team, by email at sales@cavinscorp.com and/or phone to an office
location nearest you, to find out which Desander is best suited for your well conditions.

4. CAVINS MDL. ‘MH’ COMBINATION GAS ANCHOR AND
DESANDER
The Cavins Model “MH” Gas Anchor and Desander is equipped with a larger gas
anchor body, which at high flow rates makes it more effective than the Model “G” in
separating out gas before it can enter the downhole pump.
The tool has two body assemblies. The upper body has a larger diameter than
the lower body and serves as the gas anchor. An orifice tube extends downward
through the upper body. The size of the tube may vary in order to maximize gas
separating efficiency. After the gas separates, the fluid enters the desander sub,
which is attached to the bottom of the upper body. There, solids are separated from
the fluid and fall into the mud anchor. Production fluid then flows to the pump.
