LFS is a geophysical prospecting methodology that utilizes passive seismic waves for oil & gas exploration, delineation and development of oil & gas fields that enhances productivity of exploration and development endeavours. It is a DHI (Direct Hydrocarbon Indicator) methodology that is easily applicable, cost effective, environmentally friendly and a robust alternative in finding untapped oil-gas deposits from matured or brown fields. In addition, it can be implemented to situations where conventional practices would not be an option, either due to block size, active seismic energy penetration issues, budget limitations, accessibility and/or environmental restrictions. 

​

LFS has already been applied extensively to several geological and geographical situations in Russia, Ecuador and India, wherein the success ratio in finding additional hydrocarbons is about 86%. Recently, Five out of six wells confirmed our forecast on pilot project in Gandhar Field of Cambay Basin in India. In other words, it defines productive and non-productive zones at reservoir-scale of under-developed, developed and matured fields within the limited-time and budget.
