Definitions
- the present invention relates in general to oil and gas operations and in particular to a diffuser and solids collection and measurement system for use in conjunction with oil and gas wells.
- the oil, gas, water, and solids are produced at the wellhead and then separated.
- the oil, gas, and usable amounts of water are sent for sale or reuse.
- the solids which may include solids such as fracing proppants (e.g., frac sand), are sent to a solids tank for recovery.
- the amount of solids being output from a given well or group of wells must be monitored. Current methods are based on rough estimates made by personnel observing the output being discharged into the tank. And while it would be advantageous to provide a more accurate and efficient method of determining the amount of solids being produced by a well, the nature of wellhead operations presents some significant challenges for achieving that goal. For example, the solids-bearing water is typically produced under pressure and is therefore discharged it at a high velocity.
- the principles of the present invention are embodied in a diffuser and solids collector system that provides for the collection of solids discharged from a wellhead and the accurate measurement (e.g., weighing) of the collected solids.
- a diffuser and solids collection system which includes a first baffle section having an input for receiving from a petroleum well a fluid carrying solids and a first set of internal baffles for reducing a velocity of the fluid.
- a second baffle section in fluid communication with the first baffle section has a second set of internal baffles for further reducing the velocity of the fluid.
- a solids collection container separates the solids from the fluid received from the second baffle section.
- a weighing system supported by the second baffle section and supporting the solids collection container, weighs the solids collected in the solids collection container.
- the principles of the present invention allow for an accurate measurement of the solids flowing out of a petroleum well under pressure.
- FIG. 1 depicts a representative petroleum well serviced by a diffuser and solids collector system according to the principles of the present invention

- Solids-bearing water from water/solids separators 102 a - 102 f and four phase separators 104 a - 104 c are passed to diffuser and solids collector system 100 .
- the water bearing solids such as frac sand, are delivered diffusor and solids collection system 100 , which reduces the fluid velocity, collects the solids, and allows the solids to be weighed. Once a desired amount of solids have been collected an weighed, they are discharged from diffuser and solids collector system 100 into solids tank 105 .
- FIG. 2A partially shows a preferred embodiment of diffuser and solids collection system 100 mounted on the solids tank 106 of FIG. 1 .

- the illustrated embodiment includes a vertical baffle section 201 , a horizontal baffle section 202 , and a particulate (solids) collection box 203 , which is supported by a scale 204 and pyramid support structure 205 .
- High-velocity solids-bearing water is received through an inlet 206 near the top a vertical baffle section 201 and passes through a series of internal baffles, discussed in further detail below. Additional baffles within contiguous horizontal baffle section 202 further reduce the fluid velocity.
- Particulate collection box 203 includes filter material supported by a hinged screen on the base.
- the hinged screen is associated with a handle and release mechanism, which allow a lateral edge of the hinged screen to be released and the collected solids to be dumped into solids tank 105 below, once those solids have been weighed by scale 204 .

- Vertical baffle section 201 includes vents 207 on opposing sides for discharging gases accumulated during the diffusion process.
- the upper surface of the horizontal baffle section 202 includes an aperture through which a turnbuckle extends, as discussed below, to couple scale 204 with particulate collection box 203 .
- Supports 302 at the four corners are provided for supporting diffuser and solids collector system 100 on the walls of solids tank 105 during use.
- Hinges 300 a - 300 c allow a portion of the upper surface of horizontal baffle section 202 to swing open for internal access.
- FIGS. 4A-4B show the preferred vertical baffle section 201 in further detail.
- three (3) elongated internal rectangular baffles 400 a - 400 c are provided near the top of vertical baffle section 201 , along with two (2) slanted planar baffles 401 a - 401 b extending from opposing sidewalls.

- a rectangular baffle 501 extends upward from the flat portion 503 of the floor and perpendicular to the lateral sidewalls.
- the number and configuration of the baffles of the horizontal baffle section 202 may vary.
- Aperture 502 through the floor allows a turn buckle to extend through the interior of horizontal baffle section 202 for coupling particulate collection box 203 with scale 204 , as well as to allow solid-bearing water to discharge into particulate collection box 203 .
- FIGS. 6A-6D illustrate the preferred configuration of particulate collection box 203 .
- the bottom of the solids collection box is a hinged screen 600 as shown in FIG. 6A .

- Four (4) vents 601 a - 601 d are provided for discharging gas ( FIG. 6B ).
- filter material 603 is disposed across hinged screen 600 for capturing solids as water is discharged through the bottom of particulate collection box 203 into solids tank 105 . Once the solids have been collected and weighed, hinged screen 600 is released using the release mechanism of FIG. 6D .

- Rotation of the latch around pivot point 608 is controlled by handle 604 .
- hinged screen 600 is the closed position, pin 606 on hinged screen 600 slides into slot 607 of rotating latch 605 .
- handle 604 is rotated such that latch 605 rotates away from pin 606 and pin 606 exits slot 607 in the latch 605 .
- the weighing system is shown in FIG. 7 for the preferred embodiment of diffuser and solids collector system 100 .
