Basically, complete information of the insitu state of stress means both the trends and magnitudes of the principal in situ stresses. Some stress determination techniques can provide a complete stress tensor (e.g. differential strain analysis, DSA, method), some provide an incomplete tensor (e.g. sleeve fracturing method), and some provide merely the directions of the principal stresses. The Shear wave (S-wave) splitting technique presented by Widarsono et al (1998), following the earlier works made by Yale and Sprunt (1989), obviously falls in the last category. In some cases, which usually do not require in situ stress information regarding the magnitudes as an input parameter, principal stress directions still provide useful information. Nevertheless, the expanding use of in situ stress information requires, as stated above, a complete information, which means the stress magnitudes as well as directions. Designs of hydraulic fracturing, wellbore stability, and prevention of sand problems are among examples for which information about in situ stresses is required.In relation to the requirement outlined above, the effort which results are presented in this paper was devoted to presenting efforts to predict in situ stress magnitude by using ultrasonic wave propagation. This paper mainly presents efforts to find relations between acoustic propagation and in situ stress magnitude with an ultimate goal to provide the S-wave splitting technique presented in Widarsono et al (1998) with a means for estimating stress magnitudes.","PeriodicalId":21649,"journal":{"name":"Scientific Contributions Oil and Gas","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84818064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results of microbiological laboratory tests of allanalyzed injection water samples showed three parts.

In 1990 thetotal emission of CO2 from the burning of fossil fuel was estimated at 83.8 million tonnesand by the end of the year 2020 the total emissions are estimated to be 368.3 milliontonnes. Currently, Indonesia has no specific regulation in place for controlling CO2 emissionseither in the form of an act or government regulation.Some approaches in controlling such emissions are through “common and control”and or “market based instrument” (sometimes this term is called “economic instrument”).Based on experience from developed countries, economic instrument in the form of carbontax or emission tax is preferred due to it’s effectiveness compared with the commonand control instrument.This empirical study is intended to analyze the role of economic instrument in the formof a carbon or emission tax on the energy of fossil fuel through a modified DICE (DynamicIntegrated Model of Climate Change and the Economy). The DICE model is alsocalled a “Three –Box Model” or “Two Folded Model”By using some rate of social preference (R), the model outcome suggests that appropriateoptimal taxes for petrol and coal are if model using R value of 5%. Value of carbon taxper ton in optimal condition for period of 1990-2019 is within the range $US3.90 – 40.35or $US1.06 -11.00 USD CO2 per ton. The price is equivalent to $US 0.002 – 0.024 perliter petrol and $US 1.95 -20.25 per ton coal.Based on the model output it is indicated that carbon or emission tax with optimalscenario has no significant impact on income per capita relative to “Base Case”. Shouldthe government apply tax instruments with optimal scenario, revenue of emission taxes willfall between $US 457.6 – 2,362.8 million for period 1990-2019. The revenue consists of$US 376.1 – 1,585.6 million generated from petrol and $US 81.4 – 777.2 million fromcoal.","PeriodicalId":21649,"journal":{"name":"Scientific Contributions Oil and Gas","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82469073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of fossil fuels, either flaring natural gas and burning fossil fuels, are predicted contributing GHG emissions. As a consequence, International cooperation through United Nation Framework Convention on Climate Change (UNFCCC) has pointed to increase policy interest in developing CO2 and GHG emission trading system. The system would allow the countries who have opportunities to reduce CO2 and GHG emission (generally developing countries) and sell or trade GHG emission reduction to the countries (generally developed countries). The second part of this paper will be emphasized on oil and gas reserves, production, refineries,and utilization. Indonesia oil resource as of January 1st, 2006 amounts to about 56.60 BBO, while gas resources as of January 1st, 2006 is about 334.5 TSCF. Indonesia has nine refineries owned by PT Pertamina (Persero) and six refineries owned by private. Indonesia has also voluntary participated in reducing GHG emissions by formulating energy policy, doing research on carbon capture and storage (CCS), and developing innovative projects.

Such spills might be purely an accident but some others are suspected to be deliberately spilled. Nevertheless, both cases need an identification system to trace back the spill source and eventually the spill data can be brought to the court as an evident. Previously, the identification system was conducted through a pattern recognition of n-paraffin hydrocarbons of crude oil samples which are very distinguished from their gas chromatographic (GC) pattern of n-C17, Pristane, n-C18, Phytane, and other nparaffin’s down to n-C30. Unfortunately, some crude oils have similar pattern that matching of two chromatograms could give an ambiguity result. Pattern recognition of isoprenoid hydrocarbons have been developed to characterized crude oils that potentially pollute the Indonesian waters. Differing from the n-paraffin that each hydrocarbon peak can be determined definitely, the developed method does not need to identify each of the isoprenoid hydrocarbons, instead pattern of their chromatographic separation are sufficiently distinguished. GC isoprenoid pattern recognition is made from the isoprenoid peaks that emerge between n-C17 and n- 18. It two crude oils having similar pattern of n-paraffin’s show very distinct pattern of iso-paraffin’s. The method thus can be used as complimentary step in matching the GC pattern of crude oil samples . Although in some cases GC isoprenoid peaks are not completely separated, this would not be disadvantages since their retention time and area can be measured and integrated definitely, respectively. Nevertheless, the separation of iso-paraffin peaks can be easily conducted using a recent GC method namely a comprehensive two dimensional gas chromatography (GCxGC), a method which is recommended to be implemented further in this research.","PeriodicalId":21649,"journal":{"name":"Scientific Contributions Oil and Gas","volume":"142 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88984301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
