In this paper we will discuss the results of a prototype software application to view the rig schedule generated by a reservoir simulator. Visualization of simulation rig schedules and comparing with planned rig schedule would help in identifying opportunities to improve operations. With the help of the schedule chart and rig movement data, we better the schedule generated by trying to reduce the net distance traveled by the rig and reduce the number of rigs utilized. We ensure that the overall field oil production is not affected for all the cases.Using reservoir simulation as a tool to assist in the rig planning and scheduling process has the potential to foster team collaboration between reservoir engineering, planning and operations team and facilitate better Integrated field management. The teams would appreciate the challenges associated with planning and scheduling activities for the field.

Digital Oilfield programs are underway in many oil and gas companies. The term 'Digital Oilfield' covers a wide range of areas from the usage of smart downhole sensors to the integration and transformation of data across technical and business applications for decision making in the oilfield. Ultimately the decisions made at the operational level affect the company's performance and hence Digital oilfield projects are connected with the decision making at different levels in the company. This paper analyzes different types of digital oilfield projects from the literature and draws upon the authors experience to create a perspective based on the common requirements of such projects. Such a perspective should help reducing silos within organization often looking at their own data and work processes. Examples from the area of Real-time Reservoir management and Reserves management will be analyzed by going into the details of the common elements across these areas in terms of process and data requirements, data standards and components of the work processes. By understanding the common requirements organizations can lower cost in terms of reuse and deployment of the solutions across the company. This paper will help engineers understanding of digital oilfield projects and assist in increasing the uptake of such projects within their organization. Introduction Oil and gas producing companies are challenged with increasing supply to meet the growing global hydrocarbon demand. Companies are responding to this challenge amidst an ageing workforce and deeper complex, smaller reservoirs with advanced technology and IT solutions. It is expected that the next generation of oilfield professionals will need to be far more productive that the previous generation [1]. Some viewpoints estimate integrated information technology solutions to improve productivity of about 20% of missing employee base [2]. Progress and implementation of Digital Oilfield projects are expected to bring an increase in productivity of Oilfield professionals. Published articles from CERA and Chevron clearly quantified some of the estimated and operator benefits respectively. Typical benefits include Reducing downtime, Improving ultimate recovery, Accelerating production, Improving efficiency, Reducing costs and HSE incidents. [3] Digital Oilfield Projects Several Digital Oilfield projects are underway in Oil and gas companies and different terms may be used to describe these projects / initiatives, but there is a common underlying theme. As an example one paper [4] talks about Real-time Asset Management which encompasses○'Real time Production optimization' - concerned with updating the reservoir and production model and○'Integrated Asset Performance management' - overall workflow which encompasses all the workflows in 'Oilfield Management'. This paper [4] describes the different oilfield management processes at a high level and also depicts the interplay of the sub-processes. The examples chosen in this paper are from (Real time) Reservoir Management and Reserves Management. These 2 areas are chosen because they closely related by having common data requirements. While Reservoir Management is at the asset level, Reserves Management typically is a priority at the Organizational level.

Production forecasting is an important business process requirement for operators to plan production operations, budgets, and future projects. Production forecasting can be performed over different time horizons-monthly, quarterly, yearly, and even longer-term over the life of the field. The tools used also depend on the time frame of the forecasting horizon. Activity planning or, more specifically, integrated activity/field planning is an equally important process that is tightly linked with the production forecasting. This is challenging for several reasons, such as the usage of different tools for planning and production forecasting, the lack of integration between the different systems, and disconnected business processes.A major offshore operating company (ADMA-OPCO) operates two large fields with ongoing significant brownfield modifications, inspection, surveillance, and drilling activities that impact production. Planning and scheduling these activities, taking into account the production impact and helping to minimize production losses, is a complex task that requires coordination between multiple departments. The operating company recognized significant benefits could be achieved by using integrated activity/ field planning to provide an understanding of the impact of activities on the production forecasts.To achieve this, and with support of the planning group, the operating company developed an application to enable rapid visualization of the production impact resulting from the interaction of all field activities, targeting the following objectives: 1) enhance the accuracy and confidence of Field Sustainable Production Rate (FSPR) estimates and production forecasts, 2) enable workflow consistency and process efficiency, and 3) enable the realization of improved operational efficiencies and FSPRs. This application was developed as a pilot project, working in partnership with a service company. The pilot is now moving ahead to implementation so that end users can begin working with the system to help optimize activities and minimize production downtime. There are plans to further enhance the system by integrating it with engineering/simulation models. Such integration will provide the added benefit of reducing the forecasting horizon over which the system can be used and will be closely linked with production optimization.

This paper covers different aspects of safe operations and steps organizations can take to use information technology solutions to improve the safety of their operations. Safety alerts, Information management for availability of latest documents and data, safety KPIs and integration of KPIs from different systems, GIS to track a potentially hazardous situation, Maintenance systems are examples of IT solutions for improving the safety of operations. It is also important to integrate multiple systems in order to improve workflow and reduce scope for error due to manual processes. The importance of sharing data on safety and how IT solutions can be used to share data across organizations (via a third party) will be addressed. Several different organizations where incident information is maintained will be mentioned. Safety of operations is an important aspect of HSSE in the oil and gas industry. Several steps which organizations can take to improve safety will be discussed. These steps help in making data easily available and reducing the time spent in incorporation of Integrity Management programs. Typical results of the impact of certain IT solutions in this paper on safe operations will be discussed (the results are from the literature and not of any study conducted for this paper) IT Solutions can help in improving safety in the digital oilfield. A variety of solutions to increase the safety of their operations via IT solutions exist. An overall assessment and proper project management of any newly designed system is also required to find any new risks due to the implemented systems as compared with the previous mode of working. Change management is also an extremely important aspect to make any new solution to be adopted successfully in the organization. One of the KPIs has to be to improve the safety of the operations. Introduction The oil and gas industry has traditionally seen high fatality rates and calls for increased measures to improve safety of oilfield operations. To quote a statistic from a 2005 Society of Petroleum Engineers (SPE) paper 1, the 2004 fatality rate for the onshore extraction subsector of the oil and gas industry is 8.5 times the average fatality rate for all industries in the US. Clearly, there is a lot of work to be done to improve this statistic.

Previous approaches to downhole flow allocation have used traditional nodal analysis software. This paper provides practical experience developing a solution for zonal flow allocation using an advanced completion and near-wellbore (NWB) hydraulics simulator. This solution was implemented in a green field development in the Middle East where three oil-producing wells completed with an intelligent well completion (IWC) system commingle production from multiple reservoirs. These smart wells were installed with interval control valves (ICVs) to control the commingled flow and permanent downhole gauges (PDHGs) to provide real-time pressure and temperature (P/T) data that were used in flow allocation.
