Abstract

A method for performing shale gas operation is disclosed. The method may include drilling a first well, performing a fracturing operation in the well, recovering shale gas from the first well, supplying at least part of the shale gas recovered from the well to an electrical generator, generating electricity using the generator, and transferring the generated electricity to drilling equipment used to drill a second well.

recovering shale gas from the first well;

supplying at least part of the shale gas recovered from the first well to an electricity generator;

generating electricity using the electricity generator with the supplied shale gas;

moving the first drill to a second location;

supplying a portion of the generated electricity to a second set of electrical equipment used to drill a second well at the second location;

drilling the second well substantially vertically at the second location with the first drill and the second set of electrical equipment;

moving the second drill to the second well;

drilling a second substantially horizontal well section from the second well using the second drill and the second set of electrical equipment

moving the fracturing vehicle to the second well;

supplying another portion of the generated electricity to a third set of electrical equipment; and

powering the fracturing vehicle using the third set of electrical equipment to perform a fracturing operation in the second well.

2. The method of claim 1 , wherein the fracturing vehicle, the first drill, and the second drill are compatible with each of the first set of electrical equipment, the second set of electrical equipment, and the third set of electrical equipment.

3. The method of claim 1 , further comprising installing a casing in the first well, wherein the fracturing vehicle further comprises sand blasting equipment for perforation operations, and wherein the fracturing operation further comprises:

placing the sand blasting equipment at a first position in the first well;

perforating the casing with a liquid and the sand blasting equipment at the first position;

performing wellbore sand fracturing at the first position;

repeating the perforating at intervals of 110 meters to 150 meters from the first position; and

repeating the wellbore sand fracturing at the intervals.

4. The method of claim 1 , further comprising performing well cleaning to remove sand grains from the first well.

5. The method of claim 1 , wherein the step of recovering shale gas further comprises:

performing an extraction operation to lead the shale gas out of the well and to recover liquid from at least the perforating;

separating the shale gas from the recovered liquid; and

transferring the recovered liquid to a liquid container.

6. The method of claim 1 , further comprising storing a liquid used in the fracturing operation in a liquid container, the liquid container comprising:

a first frame;

a second frame;

a foldable support structure comprising a first linkage and a second linkage forming a first supporting structure, a third linkage and a fourth linkage forming a second supporting structure, a first pivoting mechanism, and a second pivoting mechanism, wherein the first linkage and the second linkage are cross-connected and pivotally connected by the first pivoting mechanism, and wherein the third linkage and the fourth linkage are cross-connected and pivotally connected by the second pivoting mechanism;

a first sliding mechanism connecting a first end of the second linkage to the first frame;

a second sliding mechanism connecting a first end of the first linkage to the second frame;

a third sliding mechanism connecting a first end of the third linkage to the second frame; and

a fourth sliding mechanism connecting a first end of the fourth linkage to the first frame,

wherein a second end of the first linkage is connected to the first frame,

wherein a second end of the second linkage is connected to the second frame,

wherein a second end of the third linkage is connected to the first frame, and

wherein a second end of the fourth linkage is connected to the second frame.

7. The method of claim 6 , wherein the liquid container further comprises a locking mechanism in the first sliding mechanism, and wherein the method further comprises:

extending the first frame away from the second frame, thereby causing the first supporting structure and the second supporting structure to each form a respective “X” configuration, and thereby causing the first sliding mechanism to align with a locking area on the second frame; and

locking the locking mechanism to secure the liquid container in an expanded position.

8. The method of claim 7 , further comprising:

treating the liquid stored in the liquid container; and

unlocking the locking mechanism to fold the liquid container, thereby causing the first sliding mechanism and the second sliding mechanism to slide on the second frame, and thereby causing the first supporting structure to collapse and the second supporting structure to collapse.

9. The method of claim 7 , wherein the liquid container further comprises:

the third sliding mechanism positioned between the first supporting structure and the first frame;

the fourth sliding mechanism positioned between the second supporting structure and the first frame,

a second locking mechanism on the second sliding mechanism;

a third locking mechanism on the third sliding mechanism; and

a fourth locking mechanism on the fourth sliding mechanism, and

wherein the method further comprises locking the second locking mechanism, the third locking mechanism, and the fourth locking mechanism to secure the liquid container in an expanded position.

10. The method of claim 7 , wherein the locking mechanism comprises a position locking bar and a pulling link connected with the position locking bar, and wherein the locking step comprises articulating the pulling link to rotate the position locking bar.

11. The method of claim 6 , wherein the liquid container further comprises:

a net connected at least to the first supporting structure and to the second supporting structure by elastic stays; and

a soft capsule connected to the first frame, and

wherein the method further comprises supporting the soft capsule within a perimeter of the liquid container using the net.

12. The method of claim 6 , wherein the liquid container further comprises:

13. The method of claim 12 , wherein the receiving container is a rigid container.

14. The method of claim 12 , wherein the capsule is flexible.

15. The method of claim 6 , further comprising a ring structure configured to secure a top portion of a soft capsule to the first frame.

16. The method of claim 6 , wherein the first sliding mechanism further comprises a driving unit, and wherein the method further comprises electrically controlling the driving unit to push or pull the first sliding mechanism.

17. The method of claim 6 , wherein the first sliding mechanism comprises one of a sliding sleeve and a sliding track.

18. The method of claim 1 , wherein the first set of electrical equipment, the second set of electrical equipment, and the third set of electrical equipment are mobile structures.
