Implementing a Well-Integrity-Management System (PDF)
This lecture presents the framework used by BP to implement and manage well-integrity programs and discusses the Prudhoe Bay well-integrity-management system. Well integrity has received increasing attention from all aspects of the petroleum industry. Lessons learned from the Alaska implementation are discussed, including data-management systems and several case histories.

Low-Cost, Noninvasive, Remote Pipeline, and Well-Inspection Techniques (PDF)
The prevention and remediation of several flow-assurance problems require timely knowledge about the internal-deposition conditions of pipelines, sealines, and tubings. Techniques carried out by measuring and analyzing pressure signals induced by fast flow-rate changes constitute an extremely flexible, sensitive, and easily applied methodology. The basic principles of the method are illustrated, together with case histories of onshore and offshore applications.
Alberto Di Lullo leads the Flow Assurance Technologies Program of the Engineering Department of the Eni E&P Division, which coordinates operational support, design activities and R&D projects. Alberto is also (co)author of several patents and publications.
Predicting Field Performance—Thriving With Uncertainty (PDF)
Widespread access to detailed physical models and to low-cost, high-speed computing makes it possible to harness measurements of uncertainty to the task of improving field-development decisions of all types. This lecture illustrates the difficulties and pitfalls that can arise when history matching and prediction are performed deterministically with practical examples.

Wellbore-Stability Issues in Shales or Hydrate-Bearing Sediments (PDF)
This presentation draws on the application of numerical modeling, laboratory rock testing, and knowledge of the processes critical to shales and hydrate-bearing sediments to provide predictive tools for the stability of wellbores drilled in challenging formations. The lecture also touches on the application of geomechanical modeling and testing to the problem of sand-production prediction, an area of major concern to the oil industry.

She joined the Commonwealth Scientific and Industrial Research Organization to develop reactive transport models then pursued her interests in problems in petroleum geomechanics.
In an effort to enhance the deliverability potential of a tight gas well, operators sometimes overlook the “missing link” between stimulation design and the well’s post-frac production response. This presentation demonstrates that a properly designed and conducted closed-chamber PID test is a cost-effective, safe, and environmentally friendly method of obtaining critical prefrac reservoir parameters.
Robert Hawkes is Team Leader of Reservoir Services for BJ Services Company Canada. He began his career with Esso Resources. Since then, Hawkes went on to establish himself as a specialist in well-test analysis with Fekete Associates. He graduated from the Southern Alberta Institute of Technology with a diploma in petroleum engineering.
In these days of high oil prices and pressure to reduce production costs, there is an economic necessity to control, optimize, or eliminate the emulsion problem by maximizing oil/water separation. This presentation provides a summary of how emulsions form during oil production, the types of emulsions encountered, what stabilizes emulsions, and up-to-date methods for reducing emulsion-related problems.

Maximizing Oil-Recovery Efficiency and Sequestration of CO2 With “Next Generation” CO2 EOR (PDF)
Injection of CO2 into depleted and near-depleted oil reservoirs offers the potential for increasing oil recovery while sequestering industrial emissions of CO2. This presentation examines how alternative technology designs and operating strategies may enable industry to improve CO2-EOR oil-recovery efficiencies significantly, from the traditional 8 to 12% of original oil in place (OOIP) to potentially more than 20% OOIP.

Bridging Over Uncertainty: Past Performance Into Forecasting (PDF)
This presentation aims to design the concept of modeling the existing data into visualized tools to help predict the future. Engineers should use Monte Carlo simulation, decision trees, databases, expert systems, linear programming, design of experiments, and all types of artificial intelligence to state their uncertainties not as discrete values, but as continuous ranges.

Oilfield Scale—A New Integrated Approach To Tackle an Old Foe (PDF)
This lecture outlines the potential threats to production and safety that oilfield scale may present if not managed appropriately and discusses the criteria for analyzing and selecting the optimum control strategy. The general approach is illustrated by several field examples on which the author has worked very closely with a number of international oil companies.

This lecture asks what are the challenges that our industry faces in turning high-frequency data into information and knowledge that can be used to make decisions and consequently turn the decisions into action. To overcome these challenges, we have to use the technology that others have used in order to solve similar problems, successfully.
