The authors describe an automated workflow that helps mitigate sanding caused by excessive drawdown by determining the minimum tubinghead pressure (THP). The automated workflow is designed to autocalibrate, analyze, and recommend actionable measures to control THP to prevent sand ingression. This enables oil and gas operators to control sand production, resulting in production enhancement and fewer workover jobs.

Field Background

Field A is an onshore gas field producing for over 15 years. With bottomwater drive, no depletion of reservoir pressure was evident. The main reservoir sand, of Oligocene to Miocene age, is weak in nature and prone to sanding.
