Abstract
Hydraulic fracturing of subterranean formations has become more complex and detailed as information increases. Methods for calculating and monitoring reservoir pressures during treatment provide unique opportunities to adjust treatments on the fly. Treatments include acid fracturing, fracture acidizing, acid stimulation, propped acid fracture stimulation, hydraulic fracturing, slick water based hydraulic fracturing, foamed based hydraulic fracturing, foam based acid fracturing, foamed based acid diversion, any other physical particulate and fiber based hydraulic fracturing or matrix treatment.
Claims14
A method for treating a hydrocarbon formation comprising:
- a) providing a well in a hydrocarbon formation
- wherein said well is undergoing a hydraulic fracturing treatment, and
- wherein said well comprises one or more systems to measure well parameters;
- b) assembling said well parameters into one or more data packets for transmission;
- c) transmitting one or more data packets from said well to a processor;
- d) receiving one or more data packets at said processor;
- e) aligning the data from one or more data packets with one or more additional sets of data;
- f) parsing said data by parameter into relevant datasets;
- g) transforming said relevant datasets by,
- i) generating composite and dynamic hydrostatic pressure at gauge depth and at perforation depth by converting computed time-based data to capture fluid type then using data rows corresponding to fluid type to compute hydrostatic pressure,
- ii) determining fluid friction below said gauge depth by generating a friction library by fluid type and using bottom hole pressure, surface pressure, and fluid hydrostatics to generate a composite tubular friction,
- iii) calculating pressure drop in the perforation and ball seats, and
- iv) calculating bottom hole reservoir face pressure;
- h) correcting said relevant datasets;
- i) graphing said relevant datasets for a range;
- and
- j) dynamically changing one or more well processes.
A system for treating a hydrocarbon formation comprising:
