The topic which has been selected for the purpose of this literature review is MPD (Managed pressure drilling) automation. This system has resulted in heralding accurate and precise control of downhole pressure system. The MPD systems of today can not only operate in tighter envelopes of operations but more essentially, they can provide well control with dynamic real time when drilling has been undergoing. The precision dynamically has allowed access of direct nature towards the assets which were considered not drillable virtually in the previous times (Breyholtz, Nygaard and Siahaan 2010). Automation in MPD has allowed the process to boast this type of success.
Automation helps in providing functional control levels which are problematic for manual operators to gain and sustain. The inherent set up with closed looping along with methodology of conventional nature has a tendency to lend towards applications of automation within MPD (Breyholtz et al. 2010). Even after all the MPD automation advancements taken place in the previous few years, there exists a common wrong conception that present systems of MPD have the ability of providing full control of automation for the entire process of drilling. This literature review addresses this process in the best possible manner by outlining all the favourable lessons learnt and successes gained from this regard within the automation field.
From this literature review, it can be stated that MPD automation has had much influence over the way in which digging and drilling using engineering techniques are conducted (Fredericks and Reitsma 2006). Through the automation integration with MPD, it becomes possible to gain control through computers and tasks can be performed repeatedly and consistently with higher precision forever. However, solving problems of unforeseen nature is not possible. Therefore, there is a situation present wherein manual work will be needed for taking control. In these circumstances, the decision maker as a human should have proper equipment and needs to be well acquainted with the situation in a limited time along with gaining awareness of the situation in an immediate manner (Saeed, Lovorn and Arne 2012).
This needs the system of computer to depict the present situation along with suggesting the actions possibility. This type of improvement is still needed for MPD automation systems. Testing the system and validating such systems are the key requirements. Interventions are further needed to improvise the state and interventions are required to make sure that regularity can be limited in order to ensure proper functioning in relation to MPD automation. This is needed with operating costs along with schedules of rig, constraints for accommodation and availability of vessel etc. These costs further have to be decreased with the help of MPD automation.
