Trinidad has tar sand resources of about 2 billion barrels of oil on land in the Parrylands/Guapo and Brighton areas. With an oil price of over USD 25 per barrel, the commercial extraction of oil from Trinidad tar sands is viable, but it requires a careful study. The relatively small extent of this tar sand (about 10,000 acres and with depths varying from surface to less than 500 feet) and with...

The present research carries out an in-detail study of the VAPEX process as one most recent solvent-based heavy oil recovery techniques in fractured reservoirs to evaluate effect fracture parameters on performance. To achieve this purpose, several patterns with distinct features were designed and engraved glass pieces manufacture state-of-the-art microfluidic models mimicking a typical Canadian...

gas injection into heavy oil reservoirs could result in high ultimate recovery of oil. experimental studies showed that an application of a combined technology of gas assisted gravity drainage (gagd) and vapor extraction (vapex) could increase final oil recovery of a candidate viscous oil reservoir. in this paper the results of laboratory investigation are presented, including pressure-volume-t...
