Detailed evaluation of the West Kiehl alkaline-surfactant-polymer field project and it`s application to mature Minnelusa waterfloods. Annual technical report, January 1993--December 1993
1995Co-Authors: M.j. PittsAbstract:The combination of an interfacial tension agent and a mobility control agent has the potential to produce additional oil beyond a waterflood. The West Kiehl alkaline-surfactant-polymer project is the most advanced application of this chemical enhanced oil recovery technique. The West Kiehl alkaline-surfactant-polymer flood was initiated in September 1987 as a secondary application after primary recovery. A preliminary analysis of the West Kiehl alkaline-surfactant-polymer flood indicates that incremental oil of 20% of the original stock tank oil in place will be produced above waterflooding. The cost of the incremental oil will be less than $2.50 per incremental barrel. A statistical analysis of approximately 120 Minnelusa oil fields in the Powder River Basin indicates that the original stock tank oil in place exceeds one billion barrels. If the enhanced oil recovery technology implemented at West Kiehl field could be successfully applied to these fields, the potential incremental oil recovery would approach 200 million barrels. This project (1) evaluates the geological deposition environment of West Kiehl and adjacent Minneluse sand reservoirs; (2) compares the production performance results of the best geologic and reservoir performance analogs and select two fields for future study; (3) compares the two best field analogs to the westmore » Kiehl field using numerical simulation; (4) predict results of applying the enhancement technology on two mature Minneluse waterflood analog units using engineering and numerical simulation; (5) predict waterflood and polymer flood performance of the West Kiehl field using numerical simulation.« less

The Characterization of Natural Surfactant and Polymer and Their Use in Enhanced Recovery of Oil
Petroleum Science and Technology, 2011Co-Authors: Abhijit Samanta, Keka Ojha, Ajay MandalAbstract:Abstract Studies have been done to examine the applicability of natural surfactant and polymer for enhanced oil recovery. A detailed investigation has been made on interfacial and rheological properties of natural guar gum polymer and surfactant obtained from extracted soapnut shell. Based on the physicochemical properties of the surfactant and polymer solutions, optimum compositions were designed for flooding experiments. Three sets of experiments were performed to study enhanced oil recovery by injecting the same pore volume of polymer, surfactant–polymer, and alkaline–surfactant–polymer slug after brine flooding. Significantly higher additional recovery (~24% original oil in place) was obtained by alkaline–surfactant–polymer flooding compared to the other two methods over waterflooding (~50% original oil in place).

Role of oil-water emulsion in enhanced oil recovery
2010 International Conference on Chemistry and Chemical Engineering, 2010Co-Authors: Ajay Mandal, Abhijit Samanta, Achinta Bera, Keka OjhaAbstract:Oil-in-water emulsions are important in the petroleum industry as a displacing fluid for enhanced oil recovery. In the present study commercially available gear oil was used to prepare oil-in-water emulsions. Characterizations of the emulsions were performed with respect to their physicochemical properties and size distribution of the dispersed oil droplet in water phase. Experiments were also carried out to observe the efficiency of the emulsion as displacing fluid for enhanced oil recovery. Substantial additional recoveries (more than 20% of original oil in place) over conventional water flooding were obtained in the present study.

Land surface dynamics and environmental challenges of the Niger Delta, Africa: Remote sensing-based analyses spanning three decades (1986-2013)
Applied Geography, 2014Co-Authors: Claudia Kuenzer, Sybrand Van Beijma, Ursula Gessner, Stefan DechAbstract:The Niger Delta, the largest river delta on the African continent, is one of the most densely populated river deltas globally and hosts the world's third largest mangrove forest. It is a major biodiversity hot spot of our planet. At the same time the delta is home to Africa's largest oil reserves and responsible for a skyrocketing GDP development of Nigeria since the 1970s. Nigeria ranks 13th among all oil producing countries, but oil exploitation also brought with it severe environmental degradation, leading to the delta's nomination for a place on the top 10 list of the "World's Worst Polluted Places Report" in 2013. Despite the outstanding importance of the region for Nigeria, Africa, and the international community most studies published focus mainly on topics of geology, geochemistry, and environmental toxicology. Studies employing earth observation satellite data to assess Niger Delta dynamics are rare. This paper aims at contributing to an overview of Niger Delta geography and environmental threats and challenges, as well as to an understanding of Niger Delta land surface dynamics from 1986 to 2013. Covering the complete delta, we present results of land cover change analyses, results of an assessment of coastline dynamics, as well as the manifestation of oil exploitation activity as expressed via oil access canal dredging and gas flaring, monitored within the 27 year time span investigated. © 2014 Elsevier Ltd.

texas geothermal resource base a raster integration method for estimating in place geothermal energy resources using arcgis
Geothermics, 2014Co-Authors: Daniel S Zafar, Bruce CutrightAbstract:Abstract The large sedimentary basins of Texas have been and are currently the subject of intensive petroleum exploration and production. The Gulf Coast, East Texas, the Anadarko Basin, and West Texas have all produced significant volumes of both oil and gas. Many of the fields and reservoirs within these basins are now mature or reaching the end of their productive lives and present an opportunity for these deep formations to be transitioned from petroleum production to geothermal-energy production using the existing infrastructure and the legacy of geologic information created by the oil and gas industry. The Gulf Coast and the Anadarko Basin have previously been analyzed for thermal energy in place, although formations in East and West Texas have not. A problem lies in the fact that previous studies may have overestimated thermal energy by employing a more simplistic method, in which a basin is split into one or more uniform-temperature blocks for which thermal energy in place is calculated. This is overcome in the present study by using ArcGIS to create a maximum extractable depth raster for both maximum well depth and maximum extractable depth in regions of Texas. The thermal energy in place is then derived through integration of the geothermal gradient raster over the block volume defined by the maximum depth raster to estimate thermal energy in place. A reference temperature of 93 °C (200 °F) is used. The results of this methodology indicate that 1.66E + 23 Joules (2.71E + 13 bbl oil equivalent) reside in place in Texas that is accessible using existing wells. Regionally the Gulf Coast contains 3.20E + 22 Joules (5.24E + 12 bbl oil equivalent), East Texas contains 4.04E + 22 Joules (6.60E + 12 bbl oil equivalent), West Texas contains 1.42E + 22 Joules (2.32E + 12 bbl oil equivalent), and North Texas contains 4.20E + 21 Joules (6.87E + 11 bbl oil equivalent).
