Techniques for developing a hydrocarbon well that include: determining a skin increase threshold; collecting historical production data for hydrocarbon wells; determining, based on the data, skin profiles for the wells; identifying, in response to changes in skin that exceed the threshold, wells as candidates for stimulation; for each of the candidate wells: determining an observed production rate; determining a predicted production rate that corresponds to a skin of zero; determining a cost of stimulation to remediate the well; determining, based on the observed and predicted production rates, a predicted increase in production attributable to stimulation; and determining, based on the cost of stimulation and the predicted increase, a marginal production cost for increased production; selecting, based on the marginal production costs of the candidate wells, a well to be stimulated; and conducting a stimulation of the well selected.

Hydrocarbon well stimulation based on skin profiles

Provided are techniques that include determining a first set of operating parameters for a hydrocarbon well for a first period; determining, based on the first set of operating parameters, a skin factor (S); determining, based on the skin factor (S), a well model for the well; determining, a second set of operating parameters for the well for a second period; determining, based on the second set of operating parameters, well performance characteristics for the second period that include: a well pressure and a production flowrate for the second period of time; determining that the well performance characteristics for the second period are not consistent with the well model and, in response: determining, based on the second set of operating parameters, an updated skin factor; and determining, based on the updated skin factor (S), an updated well model for the well.
