Abstract

A towable separator unit (15) for oil wells (11) has a walled enclosure with tanks therein. The tanks, which are an oil-water tank (27), a water tank (29) and an oil tank (31), are separated from one another by interior side walls (39, 41). An inlet pipe (47) brings well fluids to the oil-water tank via a flume (49) that allows the contents to enter the tank and be separated. A water leg (59) allows water on the bottom to pass into the water tank; the water leg in contained inside the enclosure so as not to be subject to freezing. An oil outlet pipe (71) allows oil on top of the oil-water tank to exit and flow by gravity into the oil tank, The tanks have liquid level sensors (91 ) therein; the levels are displayed (95) on the outside and are transmitted to a remote location (99). The water and oil tanks have outlets (101,103).

Claims

AMENDED CLAIMS

received by the International Bureau on 16 September 2015 (16.09.2015)

A towable separator unit for oil wells, comprising:

a) a chassis;

b) wheels rotatable mounted to the chassis so the chassis can be towed;

c) a walled enclosure supported by the chassis and having top, bottom, exterior side and end wails, the wal led enclosure having interior side walls arranged so as to form a first tank, a second tank and a third tank, the interior side walls extending from the bottom wall to the top wall, each of the first, second, and third tanks capable of holding a fluid without leaking:

d) an inlet pipe structured and arranged to connect to an oil well, the inlet pipe communicating with the first tank so as to del iver fluids from the oil wel l into the first tank:

e) a first transfer pipe having an inlet located in a bottom region of the first tank, the first transfer pipe having an outlet located in one of the second or third tanks, the first transfer pipe located interiorly of the w alled enclosure;

f) a second transfer pipe having an inlet located in a lop region of the first lank, the second transfer pipe having an outlet located in the other of the second or third tanks, the second transfer pipe sloped downwardly from its inlet to its outlet;

g) each of the second and third tanks having an outlet.

2. The towable separator unit for oil wells of claim i wherein the first, second and third tanks are arranged longitudinally inside the walled enclosure, with the second tank between the first and third tanks.

3. The towable separator unit for oil. wells of claim 2 wherein the top wall of the walled enclosure has a step down portion that is stepped down from the first tank to the third tank, the second transfer pipe is located exterior to the stepped down portion of the top wall, further comprising a valve in the exterior portion of the second transfer pipe.

4. The towable separator unit for oil wells of claim 1 wherein the inlet pipe is connected to a flume located in the first tank, the flume extending vertically from the top wall toward the bottom wall, the flume having a lower portion with openings therein to allow the well fluid to enter the first tank, further comprising a perforated coalescer above the flume openings.

5. The towable separator unit for oil wells of claim 1 wherein the first transfer pipe comprises a water leg.

6. The towable separator unit for oil wells of claim 1 wherein the third tank has plural outlets arranged vertically along the third tank.

7. The towable separator unit for oil wells of claim 1 further comprising a level sensor in at least one of the first, second or third tanks, the level sensor providing liquid level information to a display on the exterior of the walled enclosure.

8. The towable separator unit for oil wells of claim 7 further comprising a wireless transmitter connected to the level sensor to provide level information remotely from the Well.

9. The towable separator unit for oil wells of claim 7, wherein the level sensor measures the level of oil and also measures the level of water in the respecti ve tank.

10. The towable separator unit for oil wells of claim 1. wherein the inlet of the second transfer pipe comprises a stub removably connected to the second transfer pipe and having a length so as position the inlet of the second transfer pipe at a predetermined location above the bottom wall of the first tank.

11. The towable separator unit for oil wells of claim 1 wherein the unit is road legal.
