Actual distributed temperature sensing (DTS) data and pressure data are received in response to a stimulation treatment applied to a hydrocarbon field. A pre-stimulation model is built that includes reservoir parameters, which generates simulated DTS and pressure data as a function of the reservoir parameters that include a permeability parameter and a skin parameter. In response to determining that a thermal match between the actual DTS and pressure data and the simulated DTS and pressure data is not obtained, the reservoir parameters are updated. In response to determining that the updated reservoir parameters do not match a performed pressure transient analysis (PTA), the reservoir parameters and the pre-stimulation model are updated, and the simulated DTS and pressure data are re-generated based on the updated pre-stimulation model.

Evaluating well stimulation to increase hydrocarbon production

An insertion shoe for retrofitting an undersea pipeline to permit passage therethrough of a scraper includes a plate sized to cover an opening in a branch connection of the pipeline and an inner surface structured to match the inner surface surrounding the opening. The insertion shoe can be installed in the branch connection to protect the opening without lifting the pipeline above water, so that the scraper may pass through without becoming jammed.
