In the world of oil is very common in the production system. This production system produces oil from wells after drilling and well compressions. Over time, the production of a well may decrease due to several parameters of pressure drop and the presence of clay which makes the pipe diameter narrower. There are several methods used to increase the decrease in production including adding artificial lifts such as sucker rod pump, electric submersible pump and gas lift, reservoir stimulation and pipe cleaning if the pipe diameter is reduced due to clay. The well has been installed an artificial lift is a gas lift and this well need an optimization to increase its production. The EC-6 well optimization is planned by comparing the lift-up scenario of the gas lift by adjusting the rate of gas injection and deepening the orifice injection and also an installation of electrical submersible pump. Best percentage of optimization production from EC-6 Well, last scenario is chosen which is new installation artificial lift ESP from gas lift (existing) and gaining 18.52% form existing production

在世界石油生产系统中是非常普遍的。该生产系统在钻井和井压后从井中采油。随着时间的推移，由于压力下降和粘土的存在使管径变窄，井的产量可能会下降。有几种方法可以增加产量的下降，包括增加人工举升，如有杆泵、电潜泵和气举，如果由于粘土导致管径减小，则进行油藏增产和管柱清洗。该井安装了人工举升气举，需要对其进行优化以提高产量。EC-6井的优化计划是通过调整注气速率和加深注气孔来比较气举的举升方案，并安装电潜泵。EC-6井的最佳优化产量百分比，选择最后一种方案，即从现有的气举中安装新的人工举升ESP，从现有的产量中获得18.52%的优化产量

The method used in this reserve estimation is volumetric, regulated by Badan Standar Nasional Indonesia (BSNI) (SNI 13-6482-2000). This method considers that the reservoir is a form of dimensional space so that its volume can be measured. This type of method can also be used in reserve classes ranging from hypothetical resources up to proven reserves, with parameters used in this calculation obtained through assumptions and those that are the result of preliminary survey activities, which consist of geological (MT maps), geophysics (MT maps), and geochemistry (geothermometer) surveys. Data obtained from preliminary survey activities contains data on thickness, area, and temperature of the reservoir. Other parameters that have not been obtained from preliminary survey activities, such as rock porosity and heat capacity, final temperature, water and steam saturation, internal energy of water and steam, water and steam density, recovery factor, load factor and span and are based on assumptions compiled by BSNI (SNI 13-6482-2000). In addition of using volumetric methods, calculations are also performed using the Monte Carlo simulation method. This method uses random numbers as uncertainty factors in some parameters that have been obtained from the preliminary survey as mentioned above, with the type of distribution determined based on calculation parameters..

With the reservoir temperature of 220^oC, area of 7.4 km², & thickness reaches 1550 m, the potential for geothermal reserve at "X" Field based on the volumetric method is 36.90 MWe. Meanwhile, using the Monte Carlo simulation method, the potential reserves at a 90% confidence level are around 47.93 MWe: which has the the most likely reservoir temperature of 220^oC with the range of values varies around 200-225^oC, reservoir area with the most likely value is 7.5 km² ranging from 4-11 km², and the most likely thickness value is 1550 m with 1200-1700 m for the minimum and maximum values.The calculation results of the geothermal energy reserve potential in the "X" Field are 36.90 MWe using volumetric method and 47.93 for Monte Carlo simulation method.

储量估算中使用的方法是体积法，由印尼巴丹国家标准(BSNI) (SNI 13-6482-2000)规定。该方法认为储层是一种维度空间，因此可以测量其体积。这种方法也可用于从假设资源到已探明储量的储量类别，计算中使用的参数是通过假设和初步调查活动的结果获得的，这些活动包括地质(MT图)、地球物理(MT图)和地球化学(地温计)调查。从初步调查活动中获得的数据包括储层的厚度、面积和温度。其他尚未从初步调查活动中获得的参数，如岩石孔隙度和热容、最终温度、水和蒸汽饱和度、水和蒸汽内能、水和蒸汽密度、采收率系数、载荷系数和跨度，这些参数基于BSNI (SNI 13-6482-2000)编制的假设。除采用体积法外，还采用蒙特卡罗模拟法进行了计算。该方法使用随机数作为上述初步调查中获得的一些参数的不确定因素，根据计算参数确定分布类型。储层温度220℃，面积7.4 km2，厚度1550 m，基于体积法的X气田地热储量潜力为36.90 MWe。同时，利用蒙特卡罗模拟方法，在90%置信水平下的潜在储量约为47.93 MWe，其中最可能的储层温度为220℃，取值范围在200 ~ 225℃之间，最可能的储层面积为7.5 km2，取值范围在4 ~ 11 km2之间，最可能的储层厚度为1550 m，最小值为1200 ~ 1700 m，最大值为1200 ~ 1700 m。利用体积法和蒙特卡罗模拟法分别计算出X油田的地热能储量潜力分别为36.90 MWe和47.93 MWe。

Evaluation of Cutting Carrying Index when using Diesel Oil base mud in well T is carried out on section 12-1 / 4 ", 8-1 / 2", and 5-3/4 ". This is because the use of mud on the previous section did not use Diesel Oil base mud, but only used native mud and KCL Polymer base mud. In the CCI evaluation of the Diesel Oil mud, several parameters included, Equivalent Circulating Density and rheology of diesel oil base mud. Based on the primary data on well T the ECD calculation can be done by calculating the average annulus velocity, velocity critical around annulus hole, and the pressure loss in it. The value of ECD obtained on section 12-1 / 4 "ranges from 14 ppg to 15 ppg, section 8-1/2” has 16,08 ppg to 16,4 ppg, and section 5-3 / 4" reaching 14,72 ppg as the biggest value. Based on the ECD, CCI value is obtained, this is because the ECD value describes the mud weight around the annulus hole. A good CCI value must be greater than or equal to 1, then evaluated with the results of CCI on route 12-1 / 4 "obtaining the greatest CCI value 1.6 in the jar and drill collar I. On route 8-1 / 2", CCI value evaluated in the heavyweight drill pipe section with a change in the value of 0,76 to 1,08. The CCI value on section 5-3 / 4“ changes in value from 0,65 to 1,19 in heavyweight drill pipe section.

分别在12-1 /4”、8-1 / 2”和5-3/4”井段对T井使用柴油基泥浆的携砂指标进行了评价。这是因为上一段使用的泥浆没有使用柴油基泥浆，而只使用了原生泥浆和KCL聚合物基泥浆。在柴油泥浆的CCI评价中，主要考虑了柴油基泥浆的等效循环密度和流变性等参数。根据T井的原始数据，通过计算平均环空速度、环空井周围临界速度和环空井内压力损失来进行ECD计算。12-1 / 4”段的ECD值为14 ppg ~ 15 ppg, 8-1/2”段的ECD值为16.08 ppg ~ 16.4 ppg, 5-3 / 4”段的ECD最大值为14.72 ppg。根据ECD，可以得到CCI值，这是因为ECD值描述了环空井周围的泥浆比重。良好的CCI值必须大于或等于1，然后用12-1 / 4”路线的CCI结果进行评价，得到最大的CCI值1.6，在8-1 / 2”路线上，对重型钻杆段的CCI值进行评价，其值变化范围为0.76 ~ 1.08。在重型钻杆段，5-3 / 4”段的CCI值在0.65 ~ 1.19之间变化。

X-Field is located in South Sumatra, where there are several gas fields with considerable CO2 gas potential. In this field, no research has been conducted on CO2 injection neither in the laboratory nor simulation. Therefore, the purpose of this study is to analyze the effect of CO2 injection on the value of recovery factor with one-dimensional simulation using CMG. To be able to make an accurate simulation model, it is necessary to do validation by comparing the results obtained with the CO2 injection test from experiments in the laboratory. Laboratory experimental data used in this study is from Vulin’s literature. The result of recovery factor for X-field is 98.80%. From the results of this study, it is known that the injection rate of CO2 has no effect on changes in recovery factor. However, the difference of CO2 injection pressure in these two samples influences the change in recovery factor. The higher injection pressure of CO2 in an immiscible condition is, the higher the value of the recovery factor is achieved. In addition, the difference in oil composition in these two samples affects the value of MMP, where the higher the intermediate component of a reservoir fluid is, the lower the MMP will be. X-field has a high intermediate component fraction, therefore the value of MMP obtained is lower than the MMP from Vulin’s literature. The value of MMP in X-field is 2610.68 psia

X-Field位于南苏门答腊岛，那里有几个具有相当大的二氧化碳天然气潜力的气田。在这一领域，无论是在实验室还是在模拟中都没有对CO2注入进行过研究。因此，本研究的目的是利用CMG一维模拟分析CO2注入对采收率数值的影响。为了能够做出准确的模拟模型，需要将得到的结果与实验室的CO2注入试验结果进行对比验证。本研究使用的实验室实验数据来自Vulin的文献。x场的采收率为98.80%。从本研究的结果可知，CO2的注入速度对采收率的变化没有影响。然而，两种样品中CO2注入压力的差异影响了采收率的变化。在非混相条件下，CO2注入压力越高，采收率越高。此外，两种样品中油成分的差异也会影响MMP的值，其中储层流体的中间成分越高，MMP越低。x场的中间成分分数较高，因此所得的MMP值低于Vulin文献中的MMP值。x字段的MMP值为2610.68 psia

The reservoir on Field A that has an estimated large reserve of natural gas of 10,73 TSCF would have a potential economic value when developed correctly. The natural gas reserve is planned to be extracted by utilizing 18 subsea production wells connected to five subsea manifolds at a depth of 300 ‒ 1000 m at below sea level. Gas production will be done by using FPSO. Produced gas then will be pumped to onshore processing facilities on Yamdena island through undersea pipeline that used corrosion resistant alloy as long as up to 100 km in length. The natural gas processing would either be done by building an LNG facility scenario or building a GTL facility scenario on Yamdena island. The LNG scenario would produce the natural gas into LNG and gas condensate. While the GTL scenario would produce the natural gas as a synthetic liquid fuel such as LPG, naphtha, kerosene, and diesel. The feed gas volume used on both scenarios is assumed to be 1.041 MMSCFD. The economic indicator calculated for GTL yields an NPV of 1.743,44 MMUS$ and for LNG yields 1.940,51 MMUS$. The IRR calculated for GTL yields 13,27% and for LNG yields 13,14%. The POT period calculated from cummulative cash inflow for GTL scenario will take 9,84 years time, while on LNG scenario POT will take 9,90 years time. The PI value calculated for GTL scenario yields a value of 1,46 and for LNG scenario yields a value of 1,44. Results from sensitivity analyses on economic indicator found that the parameters which has significant effect on the change of economic indicator values are product sell price.

A油田的天然气储量估计为1073 TSCF，如果开发得当，将具有潜在的经济价值。天然气储量计划通过18口水下生产井进行开采，这些井连接到海平面以下300 - 1000米的5个水下歧管。天然气生产将由FPSO完成。产出的天然气将通过长达100公里的耐腐蚀合金海底管道输送到Yamdena岛上的陆上处理设施。天然气处理将通过在Yamdena岛上建造LNG设施或GTL设施来完成。液化天然气方案将天然气生产成液化天然气和凝析气。而GTL方案将天然气作为合成液体燃料生产，如液化石油气、石脑油、煤油和柴油。假设两种情况下使用的原料气体积为1.041 MMSCFD。GTL的净现值为1.743.44百万美元，LNG的净现值为1.9405.51百万美元。GTL的收益率为13.27%，LNG的收益率为13.14%。根据GTL方案累积现金流入计算的POT期将需要9,84年的时间，而LNG方案的POT期将需要9,90年的时间。GTL方案计算的PI值为1,46,LNG方案计算的PI值为1,44。对经济指标的敏感性分析发现，对经济指标值变化影响较大的参数是产品销售价格。

Drilling is one of the important things in the drilling process, from the start of drilling to the point of reaching the intended depth, can assist the smooth process of drilling. The potential problems that can arise one of them is the drilling mud reply (loss of circulation). One way to prevent and cope with the discovery of drilling mud is dissolved. At this time Polymers Synthesis and Sago Flour as material for dissolved system. Both materials enter into the colloidal effect. The colloid solution itself is a relatively large, relatively large dispersion system within the dispersing medium.The purpose and objective in collecting these tasks is to determine the effectiveness of Synthetic and Sago Flour Polymer materials in tackling the drilling mud stock problem. Based on the results of the research found, that A sludge system can provide most of the standard specification where the value of physical properties and rheology. While the B sludge system is inversely proportional, most of it does not meet the standard specification. It can be underlined that B system with Sago Flour as LCM is effective in handling dispersion drilling mud.

C2 well is an exploration well located in south sumatera area managed by PT. MEPI in planned CSS field will be drilled to a depth of 12.000 ftTVD vertically. Planning the use of casing while drilling is done by using 16" protective casing on the trajectory 17-1/2" from a depth of 1.500 ft to 4.600 ft. The use of casing while drilling (CWD), is expected by using the casing as drillstring, then the clearance between the boreholes wall with the OD casing becomes small which will cause the event "Plastering Effect". This phenomenon is expected to isolate the wall of the drill hole which is easy to happen lost circulation. On vertical wells only need a casing method while drilling level-2 (non-retrievable) because at level-2 only casing with bits (drillshoe) only, where drillshoe will be left in the shoe casing. From the analysis results can be said on well C2 can be applied casing method while drilling because in terms of hydraulics drilling which the drill hole clearance with horsepower square inch method (HSI) and cutting lift based on cutting carrying index (CCI) is good, but for mechanics drilling needs to be considered torque, drag, and buckling loads. In terms of torque loads MLT Rings should be installed for 16” protective casing, from drag loads where the 2.000 HP rig can withstand maximum load of hookload, and 16" protective casing might not occur buckling as the maximum weight on bit (WOB) is still under critical buckling load.

C2井是位于南苏门答腊地区的一口勘探井，由PT管理。MEPI在计划的CSS油田的垂直钻探深度将达到12,000 ftTVD。随钻套管的使用计划是通过在深度为1500英尺至4600英尺的17-1/2英寸的轨迹上使用16英寸的保护套管来完成的。随钻套管(CWD)的使用是通过将套管用作钻柱来实现的，然后井壁与外径套管之间的间隙会变小，这将导致“抹灰效应”。这种现象有望隔离易发生漏失的钻壁。在直井中，当钻第二级(不可回收)时，只需要使用套管方法，因为第二级只需要使用钻头(钻鞋)进行套管，而钻鞋将留在鞋套中。从分析结果来看，C2井可以采用随钻套管法，因为就水力钻井而言，采用马力平方英寸法(HSI)和基于切削承载指数(CCI)的切削举升的钻井间隙较好，但对于力学钻井而言，需要考虑扭矩、阻力和屈曲载荷。在扭矩载荷方面，MLT环应该安装在16”保护套管上，在2000马力钻机可以承受最大钩载荷的情况下，16”保护套管可能不会发生屈曲，因为最大钻压(WOB)仍处于临界屈曲载荷下。

BN-52, BN-104, and BN-110 wells are located on the X field, PT. PERTAMINA FIELD RAMBA ASSET 1, South Sumatra. The three wells are oil-producing wells in field X. Using the Vogel equation, the IPR curve and maximum flow rate of each well are obtained, which are 152.14 BOPD, 57.2 BOPD, and 53.76 BOPD respectively. By using the exponential Decline Curve Analysis calculation method, it can be seen the rate of decline in production, as well as the time of well production to economic limit. The results of the Decline Curve Analysis show that the BN-52 well will still be in production until March 2022, and the BN-110 well can produce until March 2020. In the analysis with the Stiff & Davis Method, carbonate deposits are proven, with each Stability Index value +1.19, +1.60, and +1.35, whereas with the Skillman, Mcdonald & Stiff method there was no scale sulfate, with S values of each well at 57,272 meq / l, 54,416 meq / l, and 55,147 meq / l. The scale causes oil production to decrease, consequently the IPR curve shifts to the left. The decreasing production of the three wells is due to a scale that inhibits the flow rate. Maximum flow rate was obtained by using the Standing correlation in each well of 100.06 BOPD, 54.53 BOPD, and 28.72 BOPD. The decline in oil production caused by scales must be handled appropriately.

BN-52、BN-104和BN-110井位于南苏门答腊岛PT. PERTAMINA field RAMBA ASSET 1的X油田。3口井均为x油田的采油井，利用Vogel方程，得到了每口井的IPR曲线和最大流量，分别为152.14 BOPD、57.2 BOPD和53.76 BOPD。采用指数递减曲线分析计算方法，可以看出产量递减的速度，以及油井生产达到经济极限的时间。递减曲线分析结果表明，BN-52井将持续生产至2022年3月，BN-110井将持续生产至2020年3月。在Stiff & Davis方法的分析中，证实了碳酸盐岩沉积，稳定指数分别为+1.19，+1.60和+1.35，而在Skillman, Mcdonald & Stiff方法中，没有发现硫酸盐结垢，每口井的S值分别为57,272 meq / l, 54,416 meq / l和55147 meq / l，结垢导致产量下降，导致IPR曲线向左移动。这三口井的产量下降是由于水垢抑制了流量。每口井的最大流量分别为100.06桶/天、54.53桶/天和28.72桶/天。对水垢造成的产量下降，必须妥善处理。

Pada pemboran di lapangan minyak “X” terjadi permasalahan hilang sirkulasi lumpur (lost circulation). Lost circulation adalah hilangnya sebagian (partial lost) atau semua (total lost) dari fluida pemboran ke dalam formasi. Pada pemboran sumur Adan Bterjadi permasalahan lost circulation ketika pemboran menembus formasi Baturaja dengan lithologi batuan limestone dan sumur Cterjadi permasalahan lost circulation ketika pemboran menembus formasi Baturaja dengan lithologi limestone dan formasi Talangakar dengan lithologi 90% limestone dan 10% sandstone. Penyebab dari permasalahan lost circulation karena formasi yang memiliki lubang pori yang cukup besar sehingga terbentuk rongga-rongga atau terbentuk gua (cavern).

Dengan permasalahan lost circulation ini maka dilakukan penanggulangan pada tiap-tiap sumur A, B, dan C dengan menggunakan beberapa metode. Pada sumur Apenanggulangan dilakukan dengan Lost Circulation Material (LCM) CaCO₃ dan dilakukan penyemenan. Sumur Bini penangganan lost circulation dengan LCM CaCO₃ dan blind drilling. Sedangkan pada sumur Cpenangganan dilakukan dengan menggunakan LCM CaCO_3.

Penanggulangan masalah hilang sirkulasi lumpur yang telah dilakukan pada sumur A, B, dan sumur Cpada tiap zona loss secara keseluruhan telah dilakukan dengan baik dan pemboran tiap sumur di lapangan minyak “X” tercapai hingga kedalaman sesuai target yang diinginkan.
