The determination of casing setting depth is conducted using data on pore pressure gradients and formation fracture pressures, considering a safety factor and results from the analysis of offset wells in the field. This process sets the optimal casing shoe depth for each well trajectory, considering aspects such as protection of underground water sources and the arrangement of drilling equipment. The design and selection of casing specifications are based on international API standards. Technical aspects such as burst, collapse, axial, and triaxial stress are considered to ensure the structural integrity of the well. Overall, this report presents a methodology for designing hydrocarbon exploration wells in "A" Field, highlighting the challenges and solutions in hydrocarbon exploration in HPHT environments. This approach is aimed at achieving efficient and safe drilling, essential in the oil and gas industry."
This study examines the impact of DBH from oil and gas revenue-sharing funds on societal welfare, as measured through the HDI, focusing on recipient regencies/municipalities during 2016-2023 period. The analysis considers control variables such as per capita Gross Regional Domestic Product (GRDP), poverty rates, and regional expenditure allocations for health, education, and public services infrastructures. The result of a partial analysis indicates that DBH Migas transfer significantly positively affects the HDI at oil and gas producing municipalities. However, when analysed simultaneously with control variables, this impact, though positive, does not achieve statistical significance. Nonetheless, in municipalities that receive substantial DBH Migas funds—specifically those within the 25th percentile—the influence of DBH Migas on HDI remains both positive and statistically significant. Conversely, in municipalities not engaged in oil and gas production, both partial and simultaneous analysis of DBH Migas transfers, along with control variables, significantly enhances the HDI. At the provincial level, however, the DBH Migas variable does not demonstrate a significant positive effect on HDI, either partially or in conjunction with control variables. This study underscores the importance of policies aiming at optimizing the use of DBH Migas funds in oil and gas-producing regions, to drive development focused on human capital enhancement through economic diversification in non-oil and gas sectors. This approach aims to decrease reliance on the oil and gas industry. Since the study found that these factors have a big effect on HDI outcomes, it is also important to work to raise the GRDP, boost regional spending in areas that help HDI achievement, and reduce poverty.
