Abstract: Paraffin deposition is a problem in producing hydrocarbons that can result in losses. Paraffin can form near a wellbore, tubing, or other production facilities. Temperature differences are one of the causes of paraffin depositions. When the temperature of a fluid starts to fall below its pour point, oil flows more slowly. The temperature at which paraffin begins to form is known as the "wax appearance temperature." The development of paraffin can reduce production rates, damage production equipment, and lead to economic losses. In many cases, paraffin can also develop near the wellbore, which can cause formation damage. As a result, when paraffin begins to form, the problem must be handled as soon as possible to minimize more severe damage. The chemical method has been proven to be effective in dealing with paraffin problems. A solvent dissolves the paraffin and reduces the oil's viscosity, allowing it to flow more easily. This study aims to discuss laboratory studies of two different solvents and analyze the best scenarios that can be applied in the field to overcome paraffin problems in the Sangasanga Field and its effect on permeability improvement. The method used in this study is laboratory testing of fluid properties, solubility tests, and permeability tests. This study shows that the Parasol solvent can dissolve paraffin up to 98.2% and improve permeability up to 94.9%.

Abstract: This case study explains the uncertainty of Original Oil in Place (OOIP) calculations in reservoir static modeling of KMJ Oil Field. This field consists of 4 (four) wells in an area of ± 600 acres with high heterogeneity, so in building a 3D Model, it is necessary to analyze the sensitivity and uncertainty of geological concepts, calculations of petrophysical properties, and fluid contact. The OOIP calculation uses a probabilistic method and determines reserves related to field development. The uncertainty analysis study begins by identifying the parameters with the most significant influence (Sensitivity Analysis) in calculating OOIP in the static reservoir model. To determine the ranking of reservoir uncertainty parameters, several geological, geophysical, and petrophysical factors in building a static model must be tested according to the method used in each parameter. The OOIP calculation in the static model is calculated into three scenario categories, namely low estimate (P10), base estimate (P50), and high estimate (P90). The combination of determining facies (shale volume) porosity, fluid contact, and the cut-off is a variable/parameter that is very influential in volumetric multi-scenario calculations (probabilistic method) in the KMJ Oil Field. The results of the uncertainty analysis of the KMJ Oil Field have a low OOIP estimate (P10) of 10.86 MMSTB, a base estimate (P50) of 11.49 MMSTB, and a high estimate (P90) of 12.01 MMSTB. Furthermore, the static model used for reservoir simulation (dynamic model) in the KMJ Oil Field is the base estimate model (P50) of 11.49 MMSTB.

Abstract: The necessity for the adoption of clean and sustainable energy sources that would result in the diversification of Nigeria's energy mix has arisen as a result of the significant area of concern surrounding climate change caused by CO2 emission. It's interesting to note that Natural Gas (NG), a readily accessible alternative energy source in Nigeria with a wealth of approximately 187 trillion cubic feet (Tcf) of proven gas reserves, has remained a crucial part of the energy mix, providing adequate energy with high energy quality and low CO2 emission. However, natural gas naturally contains some acid gases and small amounts of CO2, which act as impurities. This has posed a limitation to its effective utilization due to the bottlenecks in pipeline and equipment corrosion during transportation, storage, distribution, etc. To tackle this challenge, numerous researches have been conducted on the purification of natural gas through available technologies, including the cryogenic, membranes, absorption, and adsorption methods. Additionally, the independent use of these technologies has consistently been proven to be less economical and financially demanding with longer purification time, leading to low product recovery and high energy intensity for regeneration in the NG purification processes, which leaves them uniquely challenged. In order to improve natural gas consumption, this study reviews technological techniques in the use of various natural gas purification procedures and hybrid natural gas purification processes. Membranes are used in the purification process for both the gas-absorption and bulk separation of gaseous pollutants. These strategies, created to strike a compromise between the shortcomings of membrane and absorption processes, demonstrated a better separation that contributed to long-term process improvement.
