“…These seek to recover control while having the fewest negative effects on the well's short-and long-term integrity and productivity. And more stringent tertiary well control techniques may be used if these primary and secondary measures are unsuccessful (Ruzhnikov & Yurtaev, 2021). The Driller Method, Wait & Weight Method, Concurrent Method, and Volumetric Method are some of the well control systems that are investigated for this purpose in order to choose the best and most effective well control system.…”

Well control is an essential part of any drilling operation. Improper well control procedure may result in blowout, and blowouts must be controlled to ensure a smooth drilling operation. The majority of well control incidents occur as a result of a failure to understand the fundamental principles involved. As a result, proper training and understanding are required for a drilling engineer. Every company in the world provides drilling engineers with training and an overview of various well control operations. The goal of taking well control as an engineering project is to think about and visualize the significance of well control in any drilling job. The purpose of this paper was to understand of well control procedures as well as the selection of the most effective well control system. The concurrent technique should only be utilized in exceptional circumstances; in the majority of occasions, the driller method is employed. However, if a suitable casing shoe is available, Wait & Weight method should also be used.

In a major Oil Field in Middle East, eight wells are abandoned and ten had narrow escape, while drilling surface hole due to shallow sand collapse resulting in cellar and surrounding area to subside, locally known as Cellar Collapse and carry high severity risk. Considering the out of proportion risk, drilling engineering team of project formulated an out of the box solution with enough contingencies to cope with this risk and drilled subsequent wells successfully. The task of cellar collapse prevention and mitigation plan was divided in three phases. In first phase, cellar collapse risk level was identified by generating a risk identification map of the field after analyzing almost all the wells (more than 500 wells) drilled in this field. After identifying with help of this map that cellar collapse risk exists mainly in a specific area of the field, temporary plan was not to drill in this high-risk area of +/- 2 km2 of field. However, it left this area of the reservoir undrained which was not acceptable to reservoir development. As neither leaving the area of the field undrained nor abandoning the wells due to cellar collapse was sustainable, the task was taken to the next phase to formulate a plan to make the drilling possible in this area or similar areas in this field or other fields. As such based on investigative analysis of all the previous incidents, the engineering team proposed a structural approach for an innovative and vigorous plan along with risk assessment and complete scope of contingency measures. This included pilot hole drilling, changing drilling fluid system, drilling parameters, identification of early signs of the risk, changing casing seats, utilization of casing while drilling and a pre-defined strategy to optionally cure losses based on depth of losses. Following the identification of the structure of the plan, a detailed procedure with specifics on fluid properties, expected rock behavior during drilling, detailed contingencies and flow charts were developed. With this plan, subsequent wells were drilled with 100% success, in high risk zone of cellar collapse where the plan was further updated with lessons learnt on well by well basis. This unique technique which included more than one measures targeting each specific aspect of cellar collapse mechanism, is adopted for the first time the field. Considering its success rate, it can be adopted in anywhere since most fields in middle east have incompetent shallow formations. This paper provides of details including mechanism of cellar collapse, severity of risk, conventionally attempted unsuccessfully prevention attempts, newly developed strategy followed by its successful applications and lessons learnt.

Project management defines five phases, where the project initiation (or start-up) is the most critical. That is specifically applicable to the drilling industry in the case of multi-well, multi-rig projects. This paper covers the implementation of the start-up sub-process within the integration operating model during the planning phase, the optimization of resources, and the stakeholder strategy that allowed to spud the wells in a compressed schedule and exceeded the expectations. Once the project manager was appointed, the handover process between sales and the project execution teams started. This activity marked the Project Initiation phase within the Project Management process. The Project Manager followed the Start-up sub-process to ensure all the tasks required to start a complex project were followed to spud on time and avoid HSE incidents and liquidated damages. The Start-up sub-process follows the Project Management Institute (PMI) framework and includes all the project management areas but is applied to the specificities of the customer, commercial model, and project complexity.
