Abstract Eni has more than 40 years' experience on developing and managing sour hydrocarbons Projects. That has allowed to build up in Eni a specific knowhow, which is continuously improving and updating through operational activities on assets with an high concentration of H2S in the process fluids such as Karachaganak and Kashagan in Kazakhstan, COVA in Southern Italy and the more recent Zohr facilities in Egypt. The Eni's acquired knowledge in running sour hydrocarbon assets, both offshore and onshore, has been founded on a robust risk based approach. Since the project start, risk assessments such as blowout study, Quantitative Risk Assessment, Emergency Escape Rescue Analysis, etc. results are considered the pillars for the proper design, construction, commissioning, start-up and operations phases. Specifically, SIMOPS/CONOPS methodologies and procedures and their applications in sour operational contexts are defined for managing sour hydrocarbons assets and activities.

Abstract Robust co-activities management is one key to combine continuous production and development in upstream operation. In the context of Mahakam Block, green and brown field developments are continuously adding portfolio, simultaneously with routine production activities. Huge volume of simultaneous operation in Mahakam could be seen in 2013 operation, with more than 20 million manhours, 6 Jack up Rigs, 5 Swamp Barge Rigs, 36 Well Intervention barges, 22 Construction Barges were managed. This paper will describe specifity of simultaneous operation in Mahakam Block, and presenting improvement efforts to maintain operation excellence of simultaneous activities in offshore and swamp in the past 3 years. Simultaneous operations in Mahakam are applicable in the field of production with drilling, well intervention, and construction / project. The improvement efforts went through mapping, gap analysis, workshop, and validation. Organization improvement efforts were including standard guideline to determine work criticality using quantitative approach, introduction of routine coactivity matrix and recurrent activities sheets. The guideline has successfully helping harmonization among operation sites and all stakeholders. Reinforcement of audit is another aspect contributing to overall excellence of TEPI safety and production performance in 2016.
Abstract Cluster drilling comes with its own attendant challenges; however, operators usually adopt this option in order to reduce environmental footprint and optimize cost. Drilling additional wells in an existing cluster will require simultaneous operation in order to maximize value. The philosophy underlying the rules for SIMOPS is that the interactions between operations must remain manageable (and can be demonstrated to be so) under all conditions that can be realistically foreseen. This paper focuses on four (4) activities that delivered the Ogini field HSE-Case, whose primary objective was to generate an in-house risk assessment and hazard register for Simultaneous Operations (SIMOPS) involved in drilling of the five (5) new Ogini wells namely:- Operational description of Ogini SIMOPS project, Description of HSE-MS, Risk Assessment and Remedial Action Plan (RAP). The SIMOPS for Ogini-field was limited to those activities associated with oil production from the existing wells, drilling operations and laying of flowlines for tie-in of new wells to the flowstation for production. The Ogini SIMOPS have several HSE components that require critical review; a multi-disciplinary team was constituted to assess/evaluate the Risks and generate a Hazard register used in Simultaneous Operations Planning (SIMOPS) for the project. The Scope of work of the team included coming up with the industry-acceptable strategies to carry out the following operations simultaneously viz:- Flowline Construction, Rig Move, Well Delivery and Production. A SIMOPS Planning was developed by NPDC Team and approved by DPR. Five (5) horizontal wells were drilled in a cluster (of 4.5m apart) with two producing wells; hooking up the new wells to production facility sequentially while rig was still on site. Following the review of the distances between the planned five wells and considering future intervention works in this location, after drilling and completion of first two wells, the rig was skidded some meters further away from the initial surface location to drill the subsequent wells. Extended well test was carried out on these completed wells during this operation. This reduced the identified risks associated with SIMOPS and also provided accelerated returns on initial investments.
Simultaneous Operations (SIMOPS) represent a strategic solution for oil companies as, in case of new installations, they allow to speed up the start-up of the production process while, in case of existing installations, they allow not to stop the production process. However, this solution, that is advantageous both for production and economic reasons, tends to increase the possibility for negative interferences among the different rig production phases, when hydrocarbons are extracted, and consequently increases the risk for catastrophic events impacting on humans and the environment.
Due to the potential hazard posed by SIMOPS, a dedicated chapter has been inserted in the D.lgs. 145/2015 (Italian adoption of the EU Directive 2013/30).
Until today, the evaluation of the risk induced by SIMOPS has been mainly based onto the experience of operators and on the field decisions taken during operations. The present paper instead, by means of the development of an innovative methodology, proposes an adequate approach, that is systematic and pro-active, to deal with the risk analysis of SIMOPS, as requested by oil companies that will extract hydrocarbons in Italian waters after the introduction of the EU Directive.
The final result of the analysis will be a Risk Matrix of SIMOPS, easy and intuitive to use, able to synthesise the outcomes of the risk assessment based on the requirements of the user, taking into account both the operating phases to analyse and the layout of the entire plant.
The methodology has been defined by the Working Group of the SEADOG laboratory at Politecnico di Torino in co-operation with the engineering company RAMS&E s.r.l. based in Torino.
The EU Directive 2013/30 introduced the most innovative regulations for an advanced risk analysis and it has been adopted in Italy with a proper Decree (D.Lgs. 145/2015). Stimulated by this adoption, a new laboratory has been founded at Politecnico di Torino, named SEADOG (Safety & Environmental Analysis Division for Oil & Gas), supported via the funding of the Italian Economic Development Ministry.
Abstract A simultaneous operation (SIMOP) is defined as two or more independent operations (such as drilling, workover, wire!ine, facilities construction, etc.) conducted under common operational control in which the activities of any one operation may impact the safety of personnel, equipment and/or the environment of the other(s). (Source: API Bulletin 97, Well Construction Interface Document Guidelines, 2013). Interaction of production and drilling operations may increase the likelihood of accidents in both, because the accident frequency may increase compared to normal operations. A drilling accident may have knockon effects on the production activities and vice versa thereby resulting in a loss (time, production, life, reputation). This paper presents a methodology for planning a simultaneous drilling and production operation with a tender assisted semisubmersible drilling in the Gulf of Guinea. The major risk of the operation derives from its novelty and the increased level of situational awareness required from the crew. Efficient communication, interface management and integration amongst the different disciplines and departments are crucial for an efficient and cost-effective simultaneous operation. The four M SIMOP planning [4MSIMOPPP ™] process can be broken down as: Measurement, Mitigation, Monitoring and Management. Measurement involves the scaling of the operations and scheduling in a logic system as well as the identification and assessment of latent and residual risks; both quantitative and qualitative risks will be considered. The mitigations will be considered and will include tiered contingencies and exit nodes. Robust integration of marine system, rig management system, production safety and management system and dynamic positioning system will be achieved by bridging all the systems on a common process that enhances communication. Monitoring systems to identify gaps, deviations and changes will also be developed. An ultra deepwater SIMOP process safety model specific to the Gulf of Guinea but adaptable to any other basin in the world is developed. If properly implemented and managed, it has potential to significantly reduce process safety losses based on available statistics in the industry.
Abstract Crude oil delivery expectations under timeline constraints sometimes necessitate simultaneous operations (SIMOPS) for completing field development requirements. During one such SIMOPS exercise on Field X, a major sour oilfield in causeway sites close to the Arabian Gulf in Saudi Arabia, different sub-organizations coordinated potentially different, yet complimentary operations or activities in the same location together. Challenges from the exercise included instituting an interface criteria for promoting safe operations and good technical standards for all parties. After considering work requirements, a SIMOPS team facilitated an assessment review, devised a response framework with rescue, evacuation, or emergency response plans in the event of accidental release of H2S, besides making certain other modifications to satisfy multiple stakeholders. An auditable matrix was instituted for regulating and supporting permissible simultaneous rigless and construction activities while upholding health, safety, and the environment. The scope of this paper is to show how SIMOPS was successfully planned, executed, and managed for the first time in causeway drill sites in Saudi Aramco to prevent safety and environment incidents while ensuring to meet well tie-ins and field production targets. The approach involved delineating clear reporting lines or control hierarchy for various stages of operation, avoiding schedule clashes by outlining clear scenarios for each organization. Guidelines were binding for all team members because of collaboration among multidisciplinary team members to develop suitable hazards identification and risk management plans thus formulating the foundations for the SIMOPS and ensuring safety of workers. SIMOPS facilitated the unlocking of the giant field's potential while optimizing potentially conflicting but complimentary activities on the same drill site to meet crude demand reliably and safely. Success with SIMOPS has allowed oil production delivery from the field and safe working environment for crews.
Abstract "It's widely understood that every person, no matter how conscientious and skilled, is fallible, which is why technology was developed to backstop human vulnerabilities," US National Transportation Safety Board (NTSB) Chairman Christopher A. Hart. For nearly 10 years, the offshore seismic industry has used situational awareness and simultaneous operations management technology (SA/SIMOPS) to operate more safely and at higher levels of performance. Meanwhile, onshore conventional resource developments, typified by low density drilling and relatively simple processing, have hesitated to invest in SA/SIMOPS solutions. However, unconventional resources such as shale oil and gas, and heavy oil require more complex processes including mining operations and high density pad drilling. In this challenging, low-price environment, personal and process safety, operational intelligence, and managing risk become critical success factors for unconventional oil and gas producers. Situational awareness (SA) is the accuracy of a person's and a team's current knowledge and understanding of a task and working conditions, compared to actual conditions at that time. Incomplete or poor SA can cause or worsen problems, especially in complex situations. The loss of SA was determined to be the cause of the derailment of the Washington-to-New York City passenger train, Amtrak 188 in May of 2015 (NTSB 2016). Management of simultaneous operations (SIMOPS) in onshore unconventional resources involves multiple processes (e.g. drilling, completions, facility construction, and production) being performed at the same time in close proximity. This has created a pressing need for timely, precise, actionable information to aid decision makers in their quest for more effective, safer work delivery. The ability to provide automated knowledge and rules-based systems that support decision-making serves to augment and improve existing safe work practices that are mandated by law in most jurisdictions, thus supporting regulatory compliance. SA/SIMOPS management introduces new principles, work processes, information technology tools, and changes in behavior to accomplish its safety and efficiency goals. Initiatives with similar characteristics can be found in the integrated digital oilfield (DOF) pilot projects now being implemented around the world. By applying what has been learned in these programs, the onshore installation and use of SA/SIMOPS solutions can be accelerated.
By definition Brownfield projects are executed on facilities in production, with inherent risks and constraints. The Deep Offshore dimension increases the complexity of these activities with the construction and installation work carried out on live subsea networks and FPSO's. Very often with drilling rigs operating on the location and sometimes in parallel with maintenance and integrity works. The key for safe and successful Brownfield activities, minimizing the production losses caused by required shut-downs, goes consequently through a specific management of these Simultaneous Operations (SIMOPS). This paper presents the SIMOPS management principles implemented in TOTAL E&P Angola for Brownfield activities executed on FPSO's and their subsea network, along with different innovations recently introduced to further optimize the requirement for production shut down.
