Artificial Lift Strategies for Unconventional Reservoirs: Characteristics of unconventional reservoirs lead to artificial lift challenges over the life of a well. These challenges include: rapid decline rates; wellbore geometry and construction limitations; changing flow regimes; and variable oil, water and gas ratios. Different types of artificial lift are better suited for each stage of a well’s life. However, selecting a certain method of artificial lift to optimize a particular stage may lead to added investment and/or operating costs, and thus a reduced life-cycle value for the well. This course discusses various artificial lift strategies for the life of the well to achieve maximum value from the well.
Value Creation Through Asset Management: Large investments are made in acquiring the rights to and developing an oil/gas reservoir. Value is created by producing these oil/gas reserves through drilling wells and building process facilities. Maximum value is realized by insuring the wells are producing all they can, every day, with as little downtime and low operating costs as possible. Maximum production is more than just optimizing the artificial lift method. It insures that the reservoir is producing as much as possible into the wellbore. Downtime reduction requires a continuous improvement process to achieve the highest availability of the wellbore and process equipment for use. Operating Cost reduction is necessary in order to economically produce these wells as the reservoir is depleted. This course discusses methods to achieve these objectives: Maximum Production, Minimum Downtime and Lowest Operating Cost and to structure the organization to accomplish these goals.
Chemical Program Management: The purpose of using chemicals to inhibit corrosion, scale, paraffin, hydrates, etc. is to prevent equipment failures, downhole and surface, that lead to downtime events. The use of such chemicals can be costly and insuring these expenses are actually reducing the likelihood of failures can be difficult. This course will discuss approaches to develop and implement an effective Chemical Management Program that will achieve the goals of reducing failure with confidence that the benefits of the program exceed the costs
Workovers and Completion Practices: Workovers are the means to make repairs to or perform specialty work in wellbores. Being a fundamental component of production operations in the oil/gas industry, knowledge of workover operations is critical to maintaining production from wells. Impacts of poorly performed workovers include excessive downtime and expenses. This course teaches the fundamentals of: wellbore construction, tubulars, pressure basics, rig practices, care and handling procedures, downhole tools, repair of artificial lift equipment; stimulation methods, cementing, wireline work, fishing operations and abandonment.
Impact of Wellbore Deviation on Artificial Lift: Modern directional drilling methods can result in highly complex wellbore paths that can reach long distances from surface locations, weave around other wellbores and various other configurations. These same methods can result in wellbores that prevent the use of certain artificial lift methods or can contribute to excessive failures in the artificial lift equipment. This course will examine the impact of directional changes in the drilling of a wellbore on different forms of artificial lift. Understanding the impact of directional changes can lead to a collaborative approach to drilling design and execution practices that will result in a wellbore with minimal impact to whatever artificial lift method is chosen over the life of a well.
Predictive Indicators: This session covers methods and tools to determine effective performance of artificial lift systems and potential upcoming issues and/or failures of specific equipment. There are predictive indicators that apply during the design, operation, and replacement life cycle of any lift system. Downhole conditions such as solids, paraffin, and corrosion that effect operational efficiency and production will be addressed during this session. The specific lift types covered will vary based on the audience’s requirements. Some of the topics discussed during this session include:
Rod Pumping in Unconventional Resources: As we cannot drill or complete the shale and other unconventional resources like the conventional wells, we cannot rod pump these wells as we have done historically. Errors or assumptions in the data for initial design will often led to oversized / overdesigned surface and down-hole equipment. Control methods and operational set points that have worked well in conventional wells do not necessarily apply to the unconventional plays. Special attention will be given to types of gas separation, side loading, and sinker bar utilization in deviated well bores.
Artificial Lift in Declining Production: As a well’s production declines various forms of lift are employed in an effort to optimize production. While there are wells where one form of lift is sufficient throughout the life cycle of production, there are other wells that require different forms of lift as the production rate and bottomhole pressure declines. Artificial lift staging and life cycle strategies will be addressed considering Capex and Opex. This course discusses lift method, selection, efficiency, profitability, and performance with declining rates and downhole concerns (gas/solids) to determine the best drawdown and longest projected run times. Methods and tools will be presented to help decide the optimum lift types during the life of a well.
Failure Rate and LOE Reduction Strategies: Failure rate and LOE reduction strategies are the backbone for operator excellence and efficiency especially with fluctuations in commodity prices. The art of reducing failures and LOE are considered the basic building blocks of production operations. All forms of production and some surface facility strategies will be included in the discussion. Specific attention will be paid to best practices to increase run lives, failure and LOE data acquisition and management, route cause failure analysis, and performance enhancement initiatives.
SCADA for Engineers (Advanced XSPOC): SCADA and other monitoring programs are great tools for production engineers to utilize for optimization of production and reduction of failures and/or LOE. SCADA platforms allow engineers to access real time data that can help predict damaging operating conditions as well as enhance production levels. Discussions centered on trending and alarms with regards to equipment wear, reservoir decline or damage, and operational performance are included in this session. This course will cover methods to make the most of these tools.
Root Cause Analysis: If failures are going to be reduced or eliminated we must understand the true root cause of the failure. This course will cover what data must be gathered and ways to manage / visualize the data. Several different methods of root cause analysis and tracking will be discussed. Processes for program implementation and measurement of performance will be addressed. This session will include discussions on vendor/partner participation and accountability.
Fundamentals of Production Engineering: This course is for those who are new to the role of a production engineer. All the various responsibilities and aspects of production engineering will be covered with an emphasis on producing wells effectively. The session will include an introduction to the types of equipment, options, and expected performance used in oilfield production operations. The focus of this session will be on excellence in production engineering.
Operational Excellence in Challenging Times: While it is the ultimate goal to achieve operational excellence in any environment, it can be extremely difficult during challenging times due to cost concerns. Methods and tools that can be utilized to enhance performance and improvement will be covered during the course. In the current environment energy efficiency and longer run lives assume greater importance. Discussions on NPV and long term asset value will be included in this session.
