GAS HYDRATES AN UNCONVENTIONAL RESOURCE FOR FUTURE
Abstract: AbstractThis paper presents an overcome of Gas hydrates (GH) as a potential alternate to India’s energy source. Gas hydrates are Icy-white crystalline form approximately 99% of gas and 1% of water which are found under high pressure & low temperature in places such as permafrost (polar) region, shallow offshore sediments of arctic &sub-arctic region, and Deep ocean sediments in the tropic regions. This term have attracted some Energy-Starving countries like …

Revamp of Feed Preheat Network Using Aspen Hysys in a Kero Hydro-Desulphurization Unit
Abstract: The paper is based on the revamp of feed preheat network in a Kero hydro-desulphurization unit. This revamp is beneficial as it does not require additional equipment to raise the feed temperature. Desulphurization of crude is a catalytic process used in oil and gas refining industry to remove sulphur content from refined petroleum products. Previously, feed was charged from the crude distillation unit at 103°C. Due to envisaged changes, the …

Lithological Characterization and Reservoir Characteristics by Computerized Tomography Assisted Micro Density Log of the Rock
Abstract: Lithological characterization of the unconsolidated rock from heavy oil field has been attempted using X-ray computerized tomography imagine techniques. A micro density log is generated to obtain the hidden information of such variations along the depth at microlevel, which normally is not available through conventional log. Useful exploratory leads have been obtained through characterization of the nature of reservoir using simple petro-physical techniques on conventional cores by defining reservoir grade, …

Effects of Fracture Properties on Oil Recovery in Tight Reservoirs
Abstract: Unconventional reservoirs, characterized by low permeability are gradually becoming a force to reckon with in today’s world owing to the rapid depletion of conventional resources. However, low oil production from tight reservoirs can be mitigated by implementing hydraulic fracturing. In this study, Schlumberger’s eclipse-100 simulator was used to simulate various scenarios in order to determine the best fracture geometry and the effects of fracture properties on oil recovery. The properties …

Well Injectivity Management during Geological Carbon Sequestration Activity
Abstract: It is well known that the saline aquifer formations are considered very reliable candidates for carbon sequestration because of their wide availability and they have good storage capacity. Due to high formation salinity, there a big concern about bore formation dry-out resulting from the salt precipitation in the form of halite (NaCl). The mutual solubility between CO2 and brine is responsible for creating the salt deposits, this processes may take …

Mud Acid Effect on Fines Migration Problem Using a Newly Developed Al/Zr-Based Clay Stabilizer (A): Mitigation Can Happen
Abstract: Sandstone reservoirs exhibit severe fines migration problems subsequent to conventional mud acid (HCl: HF) treatments. The acid treatment proved to be effective for a relatively short period of time, with a sudden production decline owing to either that mud acid spent rapidly in close proximity to the wellbore, causing clays to migrate into the acidized area and re-plug the formation; or that the mud acid system actually weakens the structure …

Thermodynamic modelling of the effects of high temperatures on brine fluid density
Abstract: Current trends in oil discoveries points to deep water zones characterized by temperatures ranging from 150oC to 350oC which needs good prediction of the fracture pressure and pore pressure hence imperative to continually understand temperature-density relationships of the fluids which are pumped downhole for well control. This paper seeks to propose a new, cost effective and easier method of estimating the reduction in density of brine completion fluid as it …

Estimation of Dulling Rate and Bit Tooth Wear Using Drilling Parameters and Rock Abrasiveness
Abstract: Optimisation of the drilling operations is becoming increasingly important as it can significantly reduce the oil well development cost. One of the major objectives in oil well drilling is to increase the penetration rate by selecting the optimum drilling bit based on offset wells data, and adjust the drilling factors to keep the bit in good condition during the operation. At the same time it is important to predict the …

The Reserves and Production Trends of Ghana’s Petroleum Resources
Abstract: Fossil fuels consumption has been a major source of energy in the past three decades. Globally, this accounts for over 80% of the primary energy mix. Ghana has huge hydrocarbon reserves. These reserves include fields such as the Saltpond field currently planned for decommissioning, Jubilee, Tweneboa-Enyenra-Ntomme (TEN), and the Sankofa-Gye Nyame (SGN) fields. The dwindling rate of these fields over the years has become a great concern. This work has …

Estimation of Drilling Waste Generation for Effective Waste Management
Abstract: Drilling operations remains the second generator of oil and gas waste after production activities. They are prominent among the primary sources of exploration and production waste. Wastes from drill cuttings and mud, and obnoxious gas emissions are the major contributors of these drilling wastes. These have direct and indirect impact on both humans and the environment. Poor estimation of waste may lead to solid and or liquid loadings at the …
