From Reservoir to Well: Using Technology for World-Class Results in Trinidad and Tobago

摘要

The Mahogany field in Trinidad and Tobago was developed as a dedicated gas field with reserves of 2.6 TCF to supply gas to the Atlantic LNG Plant in 1999. At that time the field was the sole provider of gas to the ALNG project. The vision was to ensure that the field was a world class producer that met the demands on the LNG Train 1 market. It was clear from the onset that the only way to deliver this vision was through the use of technology. Even more so since the field is a highly faulted, complex reservoir, that has a thin oil rim. With over 1TCF of gas already produced, the Mahogany Team is on its way to delivering this result. Technology has been the backbone of the Mahogany field development, with new technology being used from inception through drilling, reservoir monitoring and production. This intimate surveillance of the wells through new technology has generated a wealth of information. Updated simulation models have been generated using this data, which have led to a deeper understanding of the dynamic fluid distribution in the complicated reservoirs. This in turn has been the critical factor in the successful infill development of the field. It is clear that one of the critical success factors in managing the development and exploitation of the field was the use of technology. This paper will discuss the use of technology along the value chain of first drill to present and will highlight the real benefits of using technology along the way, primarily highlighting the successful use of fiber optic flowmeters, distributed temperature system, acoustic sand detectors and permanent downhole gauges.
