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%.

Primary recovery is the stage of oil production by relying on the natural ability of the driving force of the reservoir. Kind of driving force that is water drive reservoir, depletion drive, segregation drive and a combination drive. The pressure drop occurred along its produced oil from the reservoir. Reservoir so that the driving force is the main parameter in maintaining reservoir pressure balance. Through the concept of material balance is the determination of the type of propulsion quifer reservoir and the power that generates driving force parameter analysis capability and aquifer in oil producing naturally. Then do the forecasting production to limit the ability of primary recovery production phase. Combination drive depletion of water drive and the drive is a driving force in the dominant reservoir Falipu Fields with a strongly water aquifer types of drives obtained through material balance equation. Calculations using the method of water influx Havlena & Odeh used as a correction factor for determining the type of propulsion reservoir and aquifer strength. Forecasting production in the Field Falipu generate recovery factor of 41% with a pressure boundary in 2050.

Salah satu upaya stimulasi sumur yang dilakukan untuk meningkatkan produktivitas sumur yang mengalami penurunan produksi karena menurunnya permeabilitas akibat kerusakan formasi adalah dengan pengasaman matriks. Pengasaman matriks dapat dilakukan pada formasi sandstone menggunakan fluida stimulasi berbahan dasar asam Hydrofloric (HF) yang dicampur dengan asam Hydrochlorid (HCl). Dalam pelaksanaannya perlu dilakukan perencanaan desain pengasaman matriks serta mengevaluasi hasil sebelum dan sesudah dilakukan stimulasi pengasaman matriks. Penggunaan Asam Hydrofloric pada batuan sandstone karena dapat melarutkan Silikat. Asam Hydrofloric bereaksi dengan Calsium (Ca) dan Mangan (Mg) membentuk endapan. Pencampuran asam Hydrofloric dan Hydrochlorid akan dapat menghilangkan scale karena sementasi sandstone terdiri dari Ca dan Mg. Evaluasi keberhasilan stimulasi dilakukan pada sumur #H dan #P yang didasarkan pada laju produksi harian sumur, productivity index, kurva IPR (Inflow Performance Relationship) Wiggins serta harga permeabilitas sumur. Dari hasil penelitian yang dilakukan pada sumur #H mengalami peningkatan produksi dari 81.125 BOPD menjadi 121.365 BOPD dengan kenaikan harga productivity index dari 0.12 bbl/day/psi menjadi 0.2 bbl/day/psi dan kenaikan harga permeabilitas dari 11.65 mDarcy menjadi 17.79 mDarcy. Hasil pengamatan yang dilakukan pada sumur #P mengalami penurunan produksi dari 40.89 BOPD menjadi 34.94 BOPD dengan penurunan harga productivity index dari 0.10 bbl/day/psi menjadi 0.09 bbl/day/psi dan penurunan harga permeabilitas dari 10.76 mDarcy menjadi 9.42 mDarcy.

Pada proses injeksi air (secondary recovery) dimana air berfungsi mendorong minyak ke sumur produksi, distribusi air akan dipengaruhi oleh sifat heterogenitas suatu reservoir. Distribusi pendesakan air sulit untuk dideteksi karena air cenderung untuk mengalir di zona-zona yang berpermeabilitas tinggi. Oleh karena itu dalam rangka pengukuran heterogenitas reservoir pada tahap injeksi air, penting untuk mempertimbangkan pengaruh geometri aliran yang disebabkan oleh sifat dinamika batuan. Studi ini bertujuan untuk melakukan karakterisasi heterogenitas reservoir dengan injeksi air di Lapangan X. Proses pengukuran derajat heterogenitas menggunakan metode Lorenz coefficient dinamis (dynamic Lorenz coefficient) yang merupakan pengembangan dari parameter Lorenz coefficient. Sifat dinamis injeksi air yang meliputi geometri aliran injeksi dianalisis dengan menggunakan streamline. Informasi yang didapat dari simulasi streamline berupa laju alir injeksi dan time of flight (TOF) streamline akan menjadi dasar perhitungan volume pori yang tersapu oleh air injeksi. Sehingga nilai flow capacity dan storage capacity (F – F) untuk masing-masing region dapat dihitung. Selanjutnya derajat heterogenitas reservoir dihitung dengan persamaan Lorenz.

On the one hand, the existence of the oil and gas industry is needed by humans, such as for the country’s energy and foreign exchange needs,however, on the other hand, oil and gas industry activities also have great potential to pollute the environment, such as pollution of water, soil, air, and disruption of flora and fauna biodiversity. The negative impact of oil and gas activities can certainly lead to the problems such as health, economic and socio-cultural problems which will lead to community conflict. Environmental management is very necessary so that the existence of the oil and gas industry can provide benefits and welfare for humans. Knowledge about the environmental impacts is evoked from upstream oil and gas activities is very important, because communities around oil and gas operation areas will feel both direct and indirect impacts from these oil and gas activities. Especially in remote areas or inland areas where there is still a lack of information about the potential environmental impacts of oil and gas activities. Thus, education and counseling are very necessary for communities around oil and gas working areas so that they receive information and enlightenment about the potential environmental impacts resulting from oil and gas activities. The target of community service activities is the society of Sungai Pakning Village, Bukit Batu District, Bengkalis Regency, Riau Province. The issue faced was during a location survey in Sungai Pakning sub-district, Bukit Batu sub-district, Bengkalis regency, and information from the Head of Sungai Pakning sub-district, that there was still a lack of public knowledge about the environmental impacts of oil and gas activities, so it was necessary to provide education and outreach on the environmental impacts of oil and gas in Sungai Pakning sub-district. Bukit Batu District. The solution offered by the community service proposing team is to provide material regarding knowledge of the environmental impacts resulting from oil and gas operations. The approach taken was in the form of observation, discussion and question and answer with a group of partners, formulating problems and providing solutions to problems. The results achieved by this activity are that the Sungai Apit sub-district community gained knowledge about the environmental impacts resulting from oil and gas operations and CSR programs which undertaken by PT Kilang Pertamina Internasional (PT KPI) Sungai Pakning Refinery Unit.
