Patent ID: 8229880

Claim:
A method for performing acid fracturing operations of an oilfield, comprising: obtaining a plurality of historical data of acid fracturing treatments of the oilfield, wherein the plurality of historical data comprises a plurality of treatment parameters, a plurality of wellbore information parameters, and a measure of production output subsequent to historical acid fracturing operations; generating, by a computer processor, a neural network based on the plurality of historical data; identifying, in the neural network, stimulation parameters associated with optimal performance of the acid fracturing treatments, wherein the simulation parameters comprise a treatment parameter identified from the plurality of treatment parameters and a wellbore information parameter identified from the plurality of wellbore information parameters; establishing, by the computer processor, a procedure for performing the acid fracturing operations based on the stimulation parameters, comprising: determining a branching condition of the procedure based on the wellbore information parameter; extracting, from the historical data, a selected value of the treatment parameter that is associated with the optimal performance of the acid fracturing treatments, wherein the selected value is dependent on the branching condition; determining a prescription of acid fracturing treatment based on the selected value of the treatment parameter; and storing the procedure in a repository.
