Evaluating well stimulation to increase hydrocarbon production

A non-transitory computer-readable medium storing instructions executable by a computer system to perform operations comprising:

• receiving actual distributed temperature sensing (DTS) data and pressure data in response to a stimulation treatment applied to a hydrocarbon field through a well in the hydrocarbon field;
• building a pre-stimulation model that includes reservoir parameters, the pre-stimulation model generating simulated DTS and pressure data as a function of the reservoir parameters, the reservoir parameters comprising a permeability parameter and a skin parameter of the hydrocarbon field;
• determining whether a thermal match between the actual DTS and pressure data and the simulated DTS and pressure data is obtained;
• in response to determining that the thermal match between the actual DTS and pressure data and the simulated DTS and pressure data is not obtained:
• updating the reservoir parameters comprising updating the permeability parameter and the skin parameter;
• updating the pre-stimulation model based on the updated reservoir parameters;
• and
• re-generating the simulated DTS and pressure data based on the updated pre-stimulation model until the thermal match between the actual DTS and pressure data and the simulated DTS and pressure data is obtained;
• determining whether the updated permeability parameter and the updated skin parameter match a performed pressure transient analysis (PTA);
• and
• in response to determining that the updated permeability parameter and the updated skin parameter do not match the PTA:
• updating the reservoir parameters comprising updating the updated permeability parameter and the updated skin parameter;
• updating the pre-stimulation model based on the updated reservoir parameters;
• and
• re-generating the simulated DTS and pressure data based on the updated pre-stimulation model until the thermal match between the actual DTS and pressure data and the simulated DTS and pressure data is obtained and the updated permeability parameter and the updated skin parameter match the PTA.
