Abstract

The LP-ERS process is suitable for implementation on marginal and stranded crude and associated gas producing fields where associated gas is used as fuel and/or flared. Whilst flaring of associated gas is not recommended, in many instances this is unavoidable due to various techno-commercial considerations. Crude and associated gas production facilities typically receive production fluids from wells at relatively low pressures, ranging from 5 barg to 20 barg. At these pressures, there would be significant quantities of C4+ components that can be extracted as condensates and stabilized with the crude. However, conventional enhanced recovery systems currently available are bulky and costly, resulting in these enhanced recovery systems not being implemented for marginal and stranded developments.

The LP-ERS is a proprietary process, particularly developed to address the abovementioned issues, to extract condensates (C4+ components) from low pressure associated gas in a cost effective manner, without the need for bulky compression, refrigeration and dehydration facilities that are typically required for conventional enhanced recovery systems. Apart from increasing revenue due to increased volume of stabilized crude production which is generally in the range of 5% to 25% (depending on wellstream fluid GOR, etc.), the implementation of the system will also significantly reduce greenhouse gas emissions (by approximately 20%) and improve the quality of the bulk stabilized crude oil produced.
