Design and implement a custom solution for a complex under-river P&A project
In Colombia, the Halliburton Project Management team was selected to provide integrated plug-and-abandonment (P&A) services for a well located midstream in the Magdalena river. The well was in a remote area in the middle of the Magdalena riverbed, with difficult access hindered by currents and flooding. Many studies of the riverbed were carried out, the results of which were used to model various scenarios of the riverbed conditions. These study results and modeled scenarios were applied as an input for designing the structures and providing safe, customized solutions.
This project was executed utilizing specialized Halliburton technologies, such as well control services from Boots & Coots, hydraulic workover (HWO) unit from Production Solutions, and other well services involving wireline, cementing, fluids, and completion tools. Additionally, Halliburton provided engineering studies, river support barges, and well abandonment equipment. Halliburton teams also designed, built, and installed work support structures (providing piling and positioning) for the high fluctuations of water levels
The under-river P&A project was performed in a very complex environment. River conditions and water depths allowed for only a limited operational window; therefore, in-depth analysis of the location, river, and well condition were required in order to properly plan and safely execute the project.
Since the well had remained closed for 40 years and was located in the middle of Magdalena river, well integrity was another main challenge.
Other challenges that had to be addressed prior to the start of operations included:
HSE or service quality incidents
Ahead of schedule delivery
Compliance with customer requirements and regulations
