An initial study was performed 2021 to identify the best approach for this workover in order to minimize disturbance to the surface equipment during the workover. It was determined that a workover rig with the addition of scaffolds was the best option.
A Hazid review was carried out in April 2022. Upon completion of this Hazid, several additional procedures were prepared such as a procedure for transit and parking for contractors and visitors, an emergency response plan prepared in collaboration with the rig supplier, and medical screening to lower risk associated with Covid 19. During the operation, there was no Lost Time Incident, and one near miss was recorded.
Prior to the workover, Geostock Operación was in charge of preparing the platform, coordinating with ASSE the emptying process of the cavern, and disconnecting and moving surface equipment as needed.
