Abstract

A method for performing a fracture operation. A log of a formation parameter is obtained for a formation surrounding a wellbore in which the fracture operation is to be implemented. A relation is determined between the formation parameter and a parameter of the fracture operation. A value of the parameter of the fracture operation is selected based on the relation and a value of the formation parameter.

First claim

What is claimed is:

1. A method for performing a fracture operation, comprising:
obtaining, at a processor, a log of a formation parameter for a formation surrounding a wellbore in which the fracture operation is to be implemented;
determining, at the processor, a relation between the formation parameter and a parameter of the fracture operation;
determining, at the processor, local extrema for the formation parameter at a plurality of depths;
grouping, at the processor, the local extrema into a cluster to determine a value for the parameter of the fracture operation; and
creating a frac stage with the determined value.

2. The method of claim 1 , further comprising determining, from the cluster for a plurality of local minima of the horizontal stress, at least one of: (i) a location of a frac stage; (ii) a length of a frac stage; and (iii) a spacing between frac stages.

3. The method of claim 2 , wherein determining the cluster further comprises determining a local maximum of a brittleness index of the formation and a local maximum of the natural fracture intensity of the formation.

4. The method of claim 1 , wherein the formation parameter comprises at least one of: (i) a horizontal stress of the formation; (ii) a brittleness of the formation; (iii) a natural fracture intensity of the formation and (iv) available subsurface data including at least one of (a) mud logging data, (b) logging-while-drilling data, and cuttings analysis.

5. A method of performing a fracture operation, comprising:
obtaining, at a processor, a log of a formation parameter for a formation surrounding a wellbore in which the fracture operation is to be implemented;
determining, at the processor, a relation between a fracture treatment parameter and the formation parameter;
determining, at the processor, a value of the fracture treatment parameter from the relation and a value of the formation parameter; and
performing, at the processor, the fracture operation using the determined value of the fracture treatment parameter.

6. The method of claim 5 , wherein the fracture treatment parameter includes at least one of: (i) an inter-stage spacing; (ii) a stage length; (iii) a stage location; (iv) a proppant type; (v) a proppant mass; (vi) a proppant concentration; (vii) a pump rate; (viii) a surface treatment pressure; (ix) a breakdown pressure; (x) an instantaneous shut-in pressure; and (xi) an average surface treatment pressure.

7. The method of claim 5 , further comprising determining the relation from a post-frac analysis from a separate wellbore.

8. A method of performing a fracture operation, comprising:
determining, at a processor, a relation between a fracture treatment parameter of the fracture operation and a formation parameter;
determining, at the processor, from the relation and a first value of the fracture treatment parameter during the fracture operation, a value of the formation parameter;
determining, at the processor, from the formation parameter a second value of the fracture treatment parameter of the fracture operation that increases a hydrocarbon production for the formation type; and
altering the fracture treatment parameter during the fracture operation from the first value to the second value.

9. The method of claim 8 , wherein a hydrocarbon recovery of the fracture operation using the second value of the fracture treatment parameter is greater than a hydrocarbon recovery using the first value of the stimulation parameter.

10. The method of claim 8 , wherein the formation parameter is indicated of a formation type, further comprising determining the second value of the fracture treatment parameter based on the formation type.

11. The method of claim 8 , further comprising determining the relation using measurements from a previously performed fracture operation.

12. The method of claim 8 , wherein the fracture treatment parameter includes at least one of: (i) an inter-stage spacing; (ii) a stage length; (iii) a stage location; (iv) a proppant type; (v) a proppant mass; (vi) a proppant concentration; (vii) a pump rate; (viii) a surface treatment pressure; (ix) a breakdown pressure; (x) an instantaneous shut-in pressure; and (xi) an average surface treatment pressure.
