Abstract

A method of flow testing can include dispensing at least one solid material and at least one liquid into each of multiple wells in a filter plate, and allowing the liquid to flow from the filter plate only by force of gravity. A flow testing system can include a multiple well filter plate, each of the wells having disposed therein a selected combination of formation particles, a fracturing fluid composition and a liquid hydrocarbon, and a collection plate vertically below the filter plate. The fracturing fluid composition and the liquid hydrocarbon flow from the filter plate to the collection plate only by force of gravity.

First claim

What is claimed is:

1. A method of flow testing, comprising:
dispensing a solid material and a liquid into each well of a multiple well filter plate, wherein each liquid comprises a fracturing fluid composition and at least two wells of the multiple wells contain different fracturing fluid compositions;
allowing the liquids to flow from the wells in the filter plate only by force of gravity;
measuring for each well at least one of a flow rate of the respective fracturing fluid composition flowing from the well or an amount of the respective fracturing fluid composition that flowed from the well; and
selecting one of the fracturing fluid compositions for use in a subterranean well fracturing operation based on at least one of the flow rates of the fracturing fluid compositions or the amounts of the fracturing fluid compositions flowed from the wells.

2. The method of claim 1 , wherein at least one of the liquids comprises a liquid hydrocarbon.

3. The method of claim 2 , wherein the liquid hydrocarbon is selected from the group consisting of oil and liquid gas.

4. The method of claim 1 , wherein the solid material is dispensed into the wells before the liquids are dispensed into the wells.

5. The method of claim 1 , wherein the liquids are dispensed into the wells before the solid material is dispensed into the wells.

6. The method of claim 1 , further comprising heating the solid material and the liquids prior to the dispensing.

7. The method of claim 1 , further comprising heating the filter plate after the dispensing.

8. The method of claim 1 , further comprising flowing at least one of the group consisting of formation water and potassium chloride solution through the solid material, after the solid material is dispensed into the wells and before the liquid is dispensed into the wells.

9. The method of claim 1 , wherein the solid material is selected from the group consisting of proppant and formation particles.

10. The method of claim 1 , further comprising measuring at multiple times and for each of the wells a quantity of the liquid flowed from the filter plate.

11. The method of claim 1 , wherein each of the fracturing fluid compositions comprises at least one of the group consisting of a surfactant, a gel, a biocide, a clay stabilizer and a gel breaker.

12. The method of claim 1 , further comprising: introducing the selected fracturing fluid composition into an earth formation; and fracturing the earth formation using the selected fracturing fluid composition.

13. A flow testing system, comprising:
a multiple well filter plate, each of the wells having disposed therein a selected combination of formation particles, fracturing fluid compositions, and a liquid hydrocarbon, wherein at least two wells of the multiple well filter plate contain different fracturing fluid compositions; and
a collection plate vertically below the filter plate, wherein the fracturing fluid composition and the liquid hydrocarbon flow from the filter plate to the collection plate only by force of gravity.

14. The system of claim 13 , wherein the liquid hydrocarbon is selected from the group consisting of oil and liquid gas.

15. The system of claim 13 , wherein the formation particles, the fracturing fluid composition and the liquid hydrocarbon are heated to an elevated temperature.

16. The system of claim 13 , further comprising a measurement device that measures at multiple times and for each of the wells a quantity of the fracturing fluid composition and the liquid hydrocarbon flowed from the filter plate.

17. The system of claim 13 , wherein the fracturing fluid composition comprises at least one of the group consisting of a surfactant, a gel, a biocide, a clay stabilizer and a gel breaker.

18. The system of claim 13 , further comprising a control system that controls a robotic solid dispenser that dispenses the formation particles into the wells.

19. The system of claim 13 , further comprising a control system that controls a robotic liquid dispenser that dispenses into the wells at least one of the group consisting of the fracturing fluid composition and the liquid hydrocarbon.

20. The system of claim 13 , further comprising proppant in each of the wells in the filter plate.
