Oil rate will be decline at production time in a well. So, we have to produce in another layer who assume have a potential. Before we produce another layer who assumed have a potential, we need to predict oil rate to known how much oil gain. In this field research oil rate prediction in new productive zone was determine following by analogical data and near well references. In this method there is a difference determine of oil rate for each people. Cause of that, in this research using analysis statistical for oil rate predicting in new productive zone based on linear function for Productivity Index (PI) and polynomial function for watercut. Determining equation of linear and polynomial functions for oil rate prediction measuring by production and logging data for each well who assumed productive zone in area X field RMT. Based of statistically analysis for linear function known that coefficient determination (r2) = 0.9964 and polynomial function known that coefficient determination (r2) = 0.9993. This result indicated that we can use both of the functions for oil rate prediction in new productive zone in area X field RMT. After that, based on both of functions calculate oil rate prediction each wells in area X field RMT. So, known differences in oil rate prediction between oil rate data in area X field Y known is 28.13 BOPD or 0.78%.

As time goes by, there will be decreasing of production rates of a field along with decreasing pressure. This led to the necessity for further efforts to increase oil production. Therefore, pressure support is required to improve the recovery factor. Supportable pressure that can be used can be either water flooding and polymer flooding. This study aims to compare recovery factor to scenarios carried out, such as polymer flooding with different concentrations modeled in the same reservoir model to see the most favorable scenario. The method used in this research is reservoir simulation method with Computer Modeling Group (CMG) STARS simulator. The study was carried out by observing at the pressure, injection rate, and polymer concentration on increasing field recovery factor. This study used cartesian grid with the assumption of homogeneous reservoir, there are no faults or other geological condition in the reservoir, and driving mechanism is only solution gas drive. This reservoir, oil type is light oil with API gravity 40.3˚API and layer of conglomerate rock. The simulation result performed with various scenarios provides a good result. Where the conditions case base case field recovery factor of 6.7%, and after water flooding produced 25.5% of oil, whereas with tertiary recovery method is polymer flooding was carried out with four concentrations of 640 ppm, 1,500 ppm, 3,000 ppm, and 4,000 ppm obtained optimum values at 4,000 ppm polymer concentration with recovery factor 28.9%, SOR reduction final value 0,5255, polymer adsorption of 818,700 ppm, reservoir final pressure 1,707 psi, and an increase in water viscosity to 0.94 cP.

Pertumbuhan industri minyak yang cepat, meningkatnya kebutuhan bahan bakar fosil, penemuan cadangan minyak yang menurun dan sulit ditemukan, serta penurunan produksi yang diperoleh dari aset yang sudah tua menyebabkan industri minyak menerapkan metode produksi alternatif. Metode yang paling umum untuk diterapkan adalah teknik enhanced oil recovery (EOR). Salah satu metode EOR yang paling diterapkan saat ini adalah injeksi surfaktan-polimer. Proses injeksi ini sangat tergantung pada karakteristik aliran, heterogenitas batuan dan interaksi antara fluida-batuan. Oleh karena itu, perlu dilakukan studi tertentu untuk memahami mekanisme injeksi. Hal ini dapat dilakukan dengan menggunakan simulator reservoir. Studi ini dilakukan melalui analisis komparatif dari 4 (empat) jenis injeksi yaitu injeksi air, injeksi polimer, injeksi surfaktan, dan injeksi surfaktan-polimer. Dapat dilihat bahwa injeksi air tidak bekerja optimal karena kandungan air telah mencapai nilai tertinggi 98%. Injeksi polimer bisa menyapu minyak yang terkandung dalam zona permeabilitas rendah sekitar 4% dari saturasi minyak sebelumnya. Injeksi surfaktan dapat mengurangi saturasi minyak yang tersisa di reservoir (ROS) sekitar 5% dari saturasi minyak sebelumnya pada zona permeabilitas tinggi. Injeksi surfaktan-polimer bisa menyapu minyak yang terkandung dalam kedua zona permeabilitas tinggi dan rendah hingga mengurangi residual oil saturation after waterflood (SORW) dan ROS masing-masing hingga 7% dan 11% dari saturasi minyak sebelumnya. Dengan demikian, injeksi surfaktan-polimer dianggap sebagai teknik EOR yang paling cocok untuk diterapkan di Lapangan NR.

Area X merupakan bagian dari lapangan Y saat ini mengalami dalam kurun waktu 16 tahun terakhir penurunan laju alir produksi sebesar 64.4%. Diperlukan upaya untuk meningkat laju alir produksi minyak dan recovery factor dari area tersebut, upaya yang akan dilakukan adalah injeksi air atau waterflood dengan mengubah salah satu sumur produksi menjadi sumur injeksi (convert to injection). Penentuan kandidat sumur convert to injection (CTI) berdasarkan kondisi laju alir produksi, jarak antara sumur kandidat dan sumur produksi, serta korelasi antar sumur. Untuk memperoleh hasil yang optimal akan dibuat beberapa skenario yang akan disimulasikan dengan parameter rate injeksi dan penambahan perforasi. Penentuan rate injeksi dilakukan dengan uji sensitivitas terlebih dahulu dan memperhatikan tekanan fracture dari tiap lapisan. Penambahan perforasi dengan melihat korelasi dari data log yang ada sehingga sumur CTI dapat memberikan peningkatan terhadap sumur produksi. Hasil simulasi yang paling optimal dari skenario yang direncanakan diperoleh penambahan produksi sebesar 800 MSTB dan recovery factor sebesar 12.9%.

Designing a slurry with adequate strength resistance is a major objective in oil and gas completion job. Various studies and research confirms that Compressive Strength (CS) and Shear Bond Strength (SBS) are two parameter which is imperative in describing cement strength in well cementing job. This experimental study introduces a Rice Husk Ash (RHA), an alternative cement additive derived from organic waste. RHA rich in silicon oxide (SiO2) and has a pozzolanic reaction, which is correlated in enhancing cement strength. Serial cement samples with various concentration of RHA were prepared to investigate the effect of RHA concentration to CS and SBS. All samples were then Dried for 24 hours in room condition after completing mixing and molding process. A Biaxial Loading test was then performed to all samples to determine the CS and SBS values by using hydraulic press apparatus. Results from the loading test generally indicate an enhancement of CS and SBS for samples with 31%, 32%, 33%, and 34% RHA. An indication of higher CS and SBS is not found for sample with 35% RHA, comparing with 34% RHA. Thus, 34% RHA is the optimum concentration for theses study, which yield 1312. psi of CS and 158.16 psi of SBS. Through this study, there is an opportunity for transforming waste material into alternative additive with higher economic value.

Drilling is an activity carried out to obtain the desired target. Furthermore, drilling mud a very significant material involved in the drilling process, and must, therefore, obtain a rational value from the rheology. A suitable technique to achieve this goal is the use of additives, for instance, Carboxymethyl Cellulose (CMC) to improve the viscosity and air binding. This study, therefore, uses CMC produced from organic oil palm bunches as an alternative for industrial CMC. CMC of Oil Palm Empty Bunches have been tested by Energy Dispersive X-ray Spectroscopy (EDS) to determine its composition. The Empty Oil Palm Oil which uses Tenera type was taken from Riau Province, Rokan Hulu Regency, Kunto Darussalam District. In this study, this experiment used CMC Empty Oil Palm and industrial CMC to find the value of viscosity, plastic thickness, melting point, gel strength, mud cake, and filtering volume of drilling mud and prevent the loss circulation with adding each CMC composition to mud samples with amount of 2 gr, 4 gr, 6 gr, 8 gr and 10 gr. According to the EDS analysis, the Carbon (C) and Oxygen (O) content of CMC from empty oil palm bunches were 58.85% and 41.15%, respectively. In addition, the industrial standard for plastic viscosity and yield point were not attained by using 8 gr and 10 gr of this CMC.

Gas is a state asset that can be traded through state-owned or private companies to consumers. The gas produced will be processed in accordance with the regulations and consumer needs. The processing can be channeled directly to consumers or processed in a way that is more consumptive for the community, such as LPG. The use of LPG is now a necessity by the community for kitchen purposes in general. Gas supply is not necessarily evenly distributed, causing people to innovate to find alternatives by utilizing the natural surroundings. One example of nature that can be used as an alternative is to use biogas. This biogas is a solution for people who have not been reached by LPG or have difficulty getting LPG. So that people can create their own alternative energy as a backup without worrying about running out of LPG.
