        09.30 Integrated Artificial Lift with Field Development Planning

        This paper will review some of the opportunities for substantial cost saving and improved production Some of these opportunities result from recent technological advances Other improvements derive from a more integrated multi-discipline approach to oilfield development Examples will be given based on current field developments in the UK, Norway and other parts of the world

        10.15 Brent Field - Artificial Lift in a High Rate Environment

        The Brent Field is due to be progressively depressurised from early 1997 By about the year 2000 this will be achieved by using high volume downhole pumps (ESPs) Gas lift completions will also be installed in some oil producers to maximise well potential Variations on insert string technology are currently being considered for both pump and gas lift string deployment and a comprehensive test programme is being planned for late 1996 and 1997

        PUMP TECHNOLOGY

        14.15 Application for Hydraulic Drive Downhole Pumps in Production Scenarios

        This paper describes the features and the recent development activities which have enhanced the application of the hydraulic drive concept within production scenarios

        With the increased use of secondary recovery techniques and in particular pumps in artificial lift systems the hydraulically driven downhole pump has a number of technical features which are of benefit when applied to the subsea oil production scenario in the North Sea and other parts of the world

        Amongst the topics which this paper will cover are operational flexibility, wireline retrievablilty, wear resistance and gas handling capability

        15.00 Afternoon Tea




        15.30 Subsea ESP Technology: Development and Application

        This presentation will briefly address the background to the development of Subseas SP Technology, touching on the main development projects which made it possible

        The Petrobras Carapeba installation, the world's first Subsea ESP, will be briefly touched upon and the paper will focus in the Amoco Liuhia project the first field development to be based upon Subsea ESPs

        The innovative contractual structure developed between Amoco and Lasalle will then be covered. This structure played a key part in bringing the technology and in making it a success
