Operators began evaluating the shale gas block in Central China since Dec 2010. During their exploration and appraisal phases, 3 horizontal wells were drilled. Their challenges consisted of hard, abrasive formations with kicks, losses, stuck pipe and over pressure. The problems were amplified by high geological formation dip, faults, and stratigraphic uncertainties. As a result, they were unable to achieve efficient drilling using conventional motor bottom hole assembly (BHA), that made it difficult to run casing, and multiple geological side-tracks were the norm. Naturally, these wells exceeded authorization for expenditure (AFE) curves, requiring an average duration of 200 days per well. This paper features the challenges and lessons learned along with the unconventional approaches that were employed to address these challenges. Four key categories of the process were identified:They consisted of emerging technologies such as a hybrid and robust rotary steerable system (RSS), real time rate of penetration (ROP) optimization and high resolution real time logging while drilling (LWD) image data tools. In addition, drilling and best practices adopted were managed pressure drilling (MPD), high dog-leg-severity (DLS) curve with smoother borehole, and low cost rotating blowout preventer (BOP) with higher revolution per minute (RPM). In the absence of 3-D seismic data, 2-D seismic data combined with LWD data were used. Integrated Operations & Innovative Commercial Contract with local drilling service contractors had made a big impact in terms of faster well delivery and overall cost saving. Another step change was with the performance based commercial contract that helped to attain the ultimate goal to meet health, safety and environment (HSE) and time requirements.At the end of 2013, 11 horizontal wells were drilled and completed. Amongst these, one well was categorized as Top Quartile and four were Best-In-Class. Additional highlights include significantly reduced geological side-track; quadruple footage drilled per day and the reduction in drilling cost. Average well duration was significantly cut to 110 days.These accomplishments consequently enhanced the drilling schedule sequence with longer horizontal wells being planned and greater confidence of predictability and repeatability.The paper will conclude with a summary of comparative learning statistics. The team believes that this is a big step towards delivering Best-In-Class wells in complex geological structure. The next step is to realize the ambition of factory drilling at a further reduced cost to tap the unconventional plays in the Sichuan basin, and bring cleaner fuel to Central China as a replacement of coal.

When the operator embarked on an intermittent 5 well exploration, appraisal and development campaign offshore Norway between 2009 and 2012 using the West Alpha there were many challenges. The rig contract was part of a multi company consortium, the well program was varied, a 3 rd generation semi submersible rig was being used and all inclusive operating rates were high at around $1,000,000 per day.Following and expanding upon the management principles previously employed 1 , the lead operator identified an opportunity to leverage the consortium program and develop a strong relationship with the service companies, in particular the rig contractor.Health, Safety, Security and Environment (HSSE) was a key driver and over 1000 rig days were delivered without a Lost Time Incident (LTI). The lead operator was able to harmonise and standardise procedures used on every well, regardless of who operated the rig. This enabled a much clearer and more consistent message to be delivered to the work environment. This paper will outline the management process taken by the operator and contractor that enabled the following performance to be delivered: 1000 days LTI free rig operations. Record setting drilling performance with improvements up to 40%. No damage to the environment. This paper will also describe how the principles have been transferred to other parts of the operators & contractors organisations.

In early 2012, Kuwait Oil Company (KOC) initiated the planning which was followed by the implementation of the first of its kind in Kuwait, the Real Time Drilling Decision Center (RTDDC) project as a multidisciplinary collaboration solution to enhance the drilling operations efficiency and minimize the drilling non-productive time (NPT). The project consists of two ergonomically-designed collaboration centers equipped with state-of-the-art visualization technology coupled with a highly-available remote data gathering infrastructure. The real-time data is to be remotely aggregated from the initial base line of selected rig sites into a centralized office-based data repository, which will then act as the primary source of data for the optimization workflows to be carried out in both centers.The RTDDC project is currently fully operational. In order to achieve its intended value, four main pillars have been implemented:1. Since the real-time data is one of the elements of the solution backbone, a reliable highly available, high-quality remote data aggregation, transmission, and storage system is being implemented to ensure seamless data flow from the rig site to the office data repository. 2. A set of optimization workflows is defined where such data would be interpreted through intelligent computation solutions to help perform timely decisions that will aid in reducing NPT, identifying invisible lost time, and optimizing existing drilling practices. 3. An enabling collaboration environment, comprising two centers (one for development drilling and the other for deep drilling) containing advanced hardware/software technology, has been implemented to host the multidisciplinary drilling teams' personnel and to help improve the overall decision-making process. 4. Finally, a change management process is to be designed to facilitate the adoption of the real-time culture within the organization, and to infuse the optimization workflows in the day-to-day work processes.This paper will showcase the design and implementation of the above four pillars in KOC and how they will significantly contribute towards drilling operations excellence. The paper will focus on the infrastructure being implemented both in the rig site and in the corporate office. Furthermore, it will illustrate the basic monitoring and optimization workflows to be carried out in the RTDDC. And finally, it will discuss a vision for the change-management plan and its associated new work processes, applications, and facilities.
