...Materials and chemical Surfactant In this study, the experiments were carried with α-Olefin Sulfonate (AOS) surfactants. AOS is a type of anionic surfactant processed by α-Olefin gas-phase sulfonation and continuous neutralization. It is proven to form a foam with CO 2 . The surfactant...

... Abstract Although Trinidad and Tobago has an abundant supply of relatively pure CO 2 and more than 1 billion barrels of heavy oil deposits there are no active enhanced oil recovery (EOR) projects using carbon dioxide (CO 2 ). In this paper, we have performed black oil simulation studies...

... Abstract CO 2 -enhanced oil recovery (EOR) was started in 1950. Low sweep efficiency and early breakthrough issues were associated with the CO 2 -EOR system. Foam-EOR was introduced to improve the sweep efficiency instead of polymers to avoid formation damage caused by polymers. Foam stability...

... Abstract Decreasing oil production and increasing quantities of greenhouse gases continue to be an issue plaguing Trinidad and Tobago's energy sector. While CO 2 EOR has been proven to be an effective solution to both of these problems it is often overlooked in Trinidad due to the inability...

... resulted with the highest score based on the benchmarking exercise; Carbon dioxide (CO 2 ) injection and water injection were selected in second and third place respectively. In the case of CO 2 , it was recommended as Huff and Puff in order to delineate transition zones, for ease of application...

... to be contained, utilized or sold. In most cases, the gas is lean (98% methane) with low contaminants that do not require special technologies for treatment, driving down costs. However, many smaller and isolated flares at older sites continue to burn across the country and contribute to global CO 2 emissions...

... Abstract Studies have shown that CO 2 under conditions of high pressure often develops miscibility with oil, thus making it a good agent for improving the sweep efficiencies of reservoirs. A critical question is; at what pressures does CO 2 develop a miscible mixture? This paper examines...

... Abstract Low-salinity waterflooding has been an emerging EOR/IOR technique in the recent times. LSW-alternating-CO 2 injection has been particularly strong in yielding higher oil recoveries in some cases. Limited simulation studies haven been performed to properly exhibit the interpretation...

... of various injection well placements on the efficiency of Enhanced Gas Recovery (EGR) and sequestration, using reservoir simulation, in an attempt to optimize EGR coupled with CO 2 sequestration. The compositional simulator CMG-GEM was used to build a reservoir model with a simple 3D geometric shape...

... Abstract Two Enhanced Oil Recovery (EOR) methods were analyzed for producing hydrocarbons from a newly discovered JLG field using analogous information from a reservoir of similar geologic characteristics as those in southern part of Trinidad. Continuous CO 2 injection and water alternating...

... Abstract A variety of correlations for the estimation of CO 2 Minimum Miscibility Pressure (MMP) have been proposed. Although some of them are less accurate, the correlations are helpful in roughly screening a candidate reservoir for CO 2 flooding and in designing CO 2 parameters without...

... hydraulic fracturing. A CO 2 flooding process is regarded as a promising technique for improving tight oil recovery. However, the gas-oil relative permeability during CO 2 injection is not fully understood because the nanoscale pore confinement in tight oil reservoirs alters phase behavior...

... Abstract The geologic sequestration of carbon dioxide (GCS) into depleted reservoirs has been contemplated and tested in several projects globally both for permanent storage of carbon dioxide (CO 2 ) and enhancing oil recovery (EOR). Utilization of geologic sequestration as a mitigation...

... the development effect of tight oil reservoir, CO 2 flooding is proposed. Based on chang-8 tight oil reservoir in Ordos Basin, an oil sample of typical block is selected. The PVT experiments are conducted. The compositional numerical model of five-spot pattern is established with a horizontal well in the middle...

... Abstract The paper seeks to assess the technical and economic feasibility of implementing carbon dioxide enhanced oil recovery (CO 2 EOR) in Trinidad and Tobago from flue gas production whilst mitigating the effect of greenhouse gases via CO 2 sequestration. An existing power plant...

... Abstract Carbon dioxide (CO 2 ) has been used commercially to recover oil from reservoirs by enhanced oil recovery (EOR) technologies for over 40 years. Currently, CO 2 flooding is the second most applied EOR processes in the world behind steamflooding. Water alternating gas (WAG) injection...

... Abstract A combination of geologic carbon dioxide (CO 2 ) sequestration and CO 2 enhanced oil recovery (CO 2 EOR) can address the two of Trinidad and Tobago's energy sector challenges: falling oil production and increasing CO 2 emissions. Geologic storage of CO 2 in heavy oil reservoirs can...

... be considered for EOR projects are generally in an advanced state of delineation and there has been experience derived from production data for some time. Considering the scope/applicability of carbon dioxide EOR (CO 2 -EOR), the revitalization of such projects in T&T would aid in extending the use of CO 2...

... Abstract The viability of any Enhanced Oil Recovery (EOR) method lies with its ability to increase oil recovery in an economically efficient manner. The practicality of carrying out a CO 2 /surfactant enhanced oil recovery operation is affected by the high cost and large volume of surfactant...

... Complex, West Trinidad (see Figure 3 ), produce about 120 million standard cubic feet per day (mmscfd) of CO 2 in the form of waste gas. Despite the gas being so readily available and at a relatively cheap price (< US $ 0.25/mscf) there is no reason for the current disposal practice (by venting...
