Abstract

This research was carried out with the aim of determining the effect of wettability on depth pressure and electrical properties in X formation rocks. The samples used in the research were 6 samples with a diameter of 1.5 cm. Testing the wettability properties using the Amott method with the Amott Cell, testing the glass pressure using a porous plate and testing the electrical properties using a resistivity meter. Testing for the wettability of THV samples in the Amott Harvey Index is in the range -0.8901 to -0.9825. Glass pressure tests were carried out to represent the height of the transition zone in the reservoir and produced Swirr values in the range of 20% to 31% of the pore volume. The saturation of the air sample in THV-2 is stable at a pressure of 100 psi and the THV-5 sample is stable at a pressure of 200 psi. In testing the electrical properties of rocks, the formation factor curve aims to obtain the cementation factor value (m) and the resistivity index curve to obtain the saturation exponent value (n). The m value obtained is 1.73 and the n value is 3.10. The conclusion from this research is that Formation Representation of aquarium pressure against the height of the transition zone results in rocks that have strong oil wet properties will have a shorter transition zone while rocks that have weaker oil wet properties will have a longer transition zone. This research did not find a clear relationship between wettability and resistivity.

Abstract

The decline of reservoir pressure and the increase of water cut in mature oil fields often lead to a decrease in oilproduction, making wells uneconomical under natural flow conditions. Progressive Cavity Pump (PCP) is an artificiallift system commonly applied in such conditions due to its characteristics as a positive displacement pump. This studyaims to evaluate the performance of the existing PCP in Well X of Field Z and to identify underload conditions usingvolumetric efficiency as the main indicator. The analysis was conducted using secondary data through InflowPerformance Relationship (IPR) analysis with the Vogel method, nodal analysis, and evaluation of PCP performanceunder operating frequency variations ranging from 30 Hz to 60 Hz. The results show that Well X is producing atapproximately 90% of its maximum inflow capacity, indicating that reservoir inflow is the main limiting factor forproduction increase. Although increasing the operating frequency raises total fluid production, the volumetric efficiencydecreases from 85.3% at 30 Hz to 56.1% at 60 Hz, indicating underload conditions caused by the imbalance betweenpump capacity and reservoir inflow capability. The study concludes that the underload condition of the PCP is not dueto improper pump design but to limited reservoir inflow, and volumetric efficiency is an effective parameter for identifyingunderload in PCP operations.

Abstract

The Tarakan Basin in North Kalimantan is a key hydrocarbon province featuring the Meliat, Tabul, Santul, and Tarakan formations, serving as source rock, reservoir, and seal. Before 2006, the area, especially Bunyu Island, was considered a greenfield due to limited data. This changed with the successful drilling of exploration well A-01 in 2006, which confirmed oil presence in the Tabul and Meliat Formations. This study evaluates development scenarios for the TGB Field using reservoir simulation and economic analysis under a Production Sharing Contract (PSC) with a Cost Recovery scheme. CMG 2021 software was used, based on production history, petrophysical data, geological models, and pressure history. Results show that additional wells significantly improve recovery. The base case with only well A-01 yields 562,188 STB (RF 1.6%). Scenario 1 raises production to 2.99 million STB (RF 8.65%), Scenario 2 to 4.29 million STB (RF 12.38%), and Scenario 3 to 4.59 million STB (RF 13.25%). Although Scenario 3 has the best technical result, Scenario 2 is the most economically viable, with a contractor NPV of USD 1.67 million, IRR of 12%, and pay-out in 7.82 years. It also provides significant government revenue of USD 307 million.

Abstract

The NE Field is one of the fields that has produced gas since 1970 and was not developed again after that due to certain reasons. Currently, the NE Field will be developed again to support production results to achieve the national targets that have been announced. In the development of oil and gas fields, several analyzes are needed both technically and economically. In this study, before carrying out economic analysis, the things that were carried out were a review of potential reserves and estimates of NE field development. using the volumetric method, the total reserves for the NE Field were obtained at 274.32 BCF and after calculating the Recovery Factor, the Remaining Reserve was obtained at 215.46 BCF, then determining deliverability to predict production in order to achieve the target plateau rate that had been agreed upon according to the contract and by simulating 6 wells. obtained a plateau rate of 19.74 MMscf after deducting CO2 with cumulative gas production of 129 BCF and a Recovery Factor of 67%. After obtaining production, an economic analysis was carried out and it was found that PSC Cost Recovery was more profitable for the contractor with NPV results (US$ M) 87,310.06, IRR 46%, and POT 3.41 years for PSC Cost Recovery while for PSC Gross Split the NPV results were ( US$M) 69,323.11, IRR 28%, and POT 6.27 years. And in terms of sensitivity, PSC Gross Split is more sensitive than PSC Cost Recovery.

Abstract

Well FT is a multilayer oil well that is no longer able to produce under natural flow conditions due to insufficient reservoir pressure, as indicated by the absence of an intersection between the Inflow Performance Relationship (IPR) and Vertical Lift Performance (VLP) curves. To restore and optimize production, a continuous gas lift system was designed and evaluated using nodal analysis and PIPESIM simulation. The gas lift design successfully reduced the fluid column density in the tubing, lowered the bottom-hole flowing pressure (Pwf), and shifted the VLP curve to intersect with the IPR curve, enabling stable production. Sensitivity analysis was performed on key operating parameters, including gas injection rate, injection pressure, and injection depth, to determine the optimum operating conditions. The results show that an optimum gas injection rate of 3 MMSCFD provides the most effective production increase before efficiency declines. Deeper gas injection further enhances production by reducing Pwf, while an injection pressure of 600 psia was identified as the optimal condition, offering near-maximum production with improved operational stability. Overall, the implementation of continuous gas lift proved to be technically effective for enhancing the production performance of Well FT.
