Abstract:
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.
