Studi ini bertujuan untuk mengetahui dampak fluktuasi harga minyak di pasar dunia terhadap harga minyak Indonesia melalui data runtun waktu dari harga rata-rata minyak dunia dan harga rata-rata minyak Indonesia. Melalui koefisien korelasi dalam ilmu statistik, data runtun waktu dari kedua variabel harga rata-rata minyak dunia dan harga rata-rata minyak Indonesia diperoleh nilai 0,91, harga ini mendekati nilai +1 yang berarti menunjukan hubungan yang kuat antara dua variabel yaitu harga rata-rata minyak dunia dengan harga rata-rata minyak Indonesia. Meningkatnya harga minyak Indonesia tentu akan berdampak buruk pada perekonomian dalam negeri, oleh karena itu perlu adanya perhatian pemerintah untuk menempuh langkah-langkah yang bisa mengubah kebiasaan masyarakat yang semula boros BBM menjadi hemat BBM. Selain itu, dibutuhkan pula kebijakan dalam mendorong pengembangan energi alternatif.Kata kunci: minyak, ekonomi, harga

The pressure behaviour of a well can be easily measured and is useful in analysing and predicting reservoir performance or diagnosing the condition of a well. Since a well test and subsequent pressure transient analysis is the most powerful tool available to the reservoir engineer for determining reservoir characteristics, the subject of well test analysis has attracted considerable attention. A well test is the only method available to the reservoir engineer for examining the dynamic response in the reservoir and considerable information can be gained from a well test. A well test is the examination of the transient behaviour of a porous reservoir as the result of a temporary change in production conditions performed over a relatively short period of time in comparison to the producing life of field. The build up can be both the part of the test when the well is shut in and a value represented by the difference in the pressure measured at any time during the build up and the final flowing pressure. The most common megods of transient (time dependant) pressure analysis required that data points be selected such that they fell on a well-defined straight line on either semi-logarithmic or cartesian graph paper. The well test analyst must the insure that the proper straight line has been chosen if more than one line can be drawn through the plotted data. This aspect of interpretation of well test data requires the input of reservoir engineer. Equally important is the design of a well test to ensure that the duration and format of the test is such that it produces good quality data for analysis. The results obtained from transient pressure analysis are used to discover the formation damage by detemining skin. This experiment will be analyzed oil well which is NA-20 well in Senja field. The results from the analysis of the data obtained on NA-20 well is 4.84 mD permeability, skin +1.42, pressure changes due to skin (ΔPskin) 264.384 psi, and flow efficiency 0.842 with 851.61 ft radius of investigation. The result from the analysis of the well showed that NA-20 well in Senja field have formation damage.

Drilling operation is process for creating a hole before production operation. “CT” Well and “Y” Well is located at same area which is Z Block. Those wells are vertical offshore wells. “CT” Well had been drilled on 1971 before “Y” Well was drilled on 2009.While drilling “CT” Well occurred total loss circulation on 12 ¼” at 3928 ft and cured with injection of 375 bbl LCM (Loss Circulation Material) with concentration 300 ppb but the loss circulation still occurred. Then total loss circulation occurred again at depth 4343 ft and 4545 ft. It cured with the same method but it didn’t succeed at all. Thus, using blind drilling method is the only option to anticipate the loss. This operation took 17 days using those methods.Well “Y” on 12 ¼” was drilled conventionally. When it reached depth 2910 ft occurred total loss circulation. Based on “CT” Well, using Under Balanced Drilling Method is the best way to anticipate the total loss circulation. This method only took 8 days Keywords : Grid Model Reservoir, Single Porosity, Grid Cell.

Y Field is a field that located on Sumatera Island. That located at Jambi Province precisely. This X well which will be drilled is a development wells at Y field. All of the draw well in this Y Field is an onshore wells. This X well shall be drilled using water-based mud. This water-based mud is used because it is cheaper and more economical than using oil-based. But, this mud needs tobe added an additive because the water-based mud has a deficiency in controlling the formations of clay. Planning of mud system for X well is using method of the offset wells, that is using around of wells data to be used as a comparison. This first X well drilled for hole section 26” by size of casing 20” with depth up to 150 ft and mud which used is type of gel/water. And then it is continued with hole section 17 ½” by size of casing 13 3/8” with continuing the former mud of drilling in hole section 26”. The depth starts from 150 ft until 1000 ft. The next hole section is 12 ¼” by size of casing 9 3/8” which a depth that starts from 1000ft until 4100 ft and using new of mud with polymer mud. Last hole section 8 ½” without casing and using polymer mud to continuing the previous drilling from the depth of 4100 ft until 4900 ft. Problem that faces by this draw well is the presence of faults and high pressure at depths below 1000 ft, so it needs to be prepared LCM (Loss Control Material) and Jumbo Bag to overcome the occurrence of kick.

Drilling operations always require fluid in their activities. Because to penetrate the soil and rocks will be very easy with the use of fluid. The fluid will help soften the soil and rocks making it easier for the drill bit to penetrate it. Drilling fluid is also needed to attach the casing to the drill wall. So that the wall does not collapse, as media logging and so on. Of course, each drilling zone (surface zone, intermediate zone, and production zone) has different characteristics and different additive substances are needed. This study wants to find out the function of the use of calcium chloride additives on the nature of cement hardness and choking time. This research is important because it will be known this addictive nature as a retarder or accelerator. By knowing the nature of this additive so that it can be used in the right zone. Testing on Calcium Chloride additive for the value of compressive strength is very effective at a concentration of 8%, 24-hour immersion time and a temperature of 150 ° F with a test result of 4483 psi. Whereas, at temperatures of 80 ° F and 100 ° F, the maximum value of compressive strength for Calcium Chloride additive occurs at a concentration of 10% with a test result of 2393 psi and 2888 psi. Based on the data presented, temperature plays an important role in testing the thickening time of a cement sample. The addition of calcium chloride additive functions as an accelerator.

Fisika adalah suatu ilmu yang mempelajari tentang alam semesta, baik mempelajari partikel yang berukuran kecil sampai dengan planet yang berukuran makro. Bidang kajiannyapun beragam dari mempelajari struktur bumi sampai dengan sistem tata surya. Salah satu penerapan ilmu fisika adalah di bidang industri perminyakan. Perkembangan teknologi perminyakan dewasa ini sangat pesat sekali, salah satunya adalah dalam pengeboran atau drilling. Operasi pemboran tidak pernah lepas atau mengabaikan penggunaan fluida pemboran. Fluida pemboran terdiri dari dua pekerjaan yakni rekayasa lumpur pemboran dan penyemenan.Penyemenan diperlukan supaya dapat mengurangi permasalahan sewaktu melakukan pemboran pada trayek selanjutnya. Tingkat keberhasilan penyemenan ditentukan oleh 2 hal yakni kualitas bahan penyemenan yang terdiri dari bahan dasar semen serta aditif dan teknik pelaksanaan penyemenan. Pada penambahan Sodium Lignosulfonate terjadi penurunan nilai compressive strength dan menaikan nilai thickening time pada konsentrasi 1% adalah 255 menit dengan temperatur 80°F karena pada dasarnya additive ini bersifat retarder. Pengujian additive Calcium Chloride untuk nilai compressive strength sangat efektif pada konsentrasi 7% dengan hasil test 4483 psi pada temperatur 150°F, sedangkan pada temperatur 80°F dan 100°F hasil test yang didapat sebesar 2393 psi dan 2888 psi, sedangkan nilai thickening time menurun dikarenakan sifat additive ini sebagai accelerator.

Indonesia has large enough gas reserves to meet household and industrial needs. It's just that, the price or the existing gas-related system is not maximal yet. One of the things that can ease the burden on the state is the use of household gas networks, some people are still hesitant to use it even though the price is relatively cheap compared to LPG. In determining the gas price, one of the components that has an effect on determining the gas price is the toll fee through pipes to be channeled. So the authors aim to conduct this research in order to educate and maximize solutions for energy dependency, for example the location I took is located in North Sumatra Province, with a pipeline stretching 156.5 km from X1 to X3. With OD 16 "along 18.5 km and existing OD 12" along 138 km. The maximum capacity of the two pipes is 150 MSCFD and 75 MSCFD, and the average volume that flows is not up to 10%. The construction of the pipe requires a cost of $ 42,391,716 USD, and nearly 55% of the total is pipe material including fittings, coatings, and others. With an average annual revenue of $ 11.561943 this project alone should have been able to return on investment for less than 5 years. With tariff analysis, the amount can be optimized with volume by reducing a few dollars per MSCF, to $ 7.49 making it more economical.
