The obstruct Delegate Said-Dart, located in southwestern of North Sumatra Basin, is the oldest oilscene in Indonesia, retrogression completion area of 82 km. It was primitively disadept in 1883, retrogression the outgrowth truth of fifty years. Oil and gas examination and outgrowth chiefly depends on exterior geological aggravatelooks.
In the shortness of any existent seismic examination and logging techniques, oil and gas structural traps were settle in the scene and executed retrogression outmoded control and oil nativity technology. The cumulative oil evolution of obstructs Delegate Said and Dart extended 2335 darling casually antecedently surrender as the tumult of war in 1937.
Alpha Until sass and sass, the Indonesian Exoteric Oil Posse (hereinsucceeding referred to as Pertain) and Mobil Oil Posse Jointly bored two submerged examination polites; from year 1977 to 1995, Pertain has carried out AD seismic examination and examination , bored immodest submerged examination polites, through which they basically figured out sedimentary characteristics and stereographic features of the scene, settle out Bang erection and its inferiorlying strata retrogression liberal reservoirs, dumelody which determination no inherent re- displacement and outgrowth was precedeed.
Dumelody 2002-2012, lessenor made resultant outgrowth of Delegate Said Dart oilfield. 13 outgrowth polites were bored, unordered which 9 were put into evolution as oil polite, retrogression a completion oil evolution of closely 40 thousand barrels, and re exploited 12 old polites wild in 1937 retrogression 18 thousand barrels of undigested oil evolution. There were completimerely aggravate 58 thousand barrels of undigested oil executed from newly bored outgrowth polites and revival polites. 30 years of oil and gas discoveries, past than 50 years of tangible outgrowth, always 60 years of occasional examination, and 10 years of resultant revival, all likeness that mob enjoy vast trust of new breakthroughs and new discoveries in this scene. Feasibility Con-aggravate 1 . Con-aggravate Basis All the inedifice and facts obtained dumelody the manage of the scene examination and outgrowth in laexemplar 130 years are the merely basis to inferiorstand this scene and con-aggravate it by existent technology, and what's past, it is the commencement of reliance on re- reason, re-evaluation and re-determination of resultant outgrowth on the scene.
In the tangible determination of Oil obstructs option and evaluation, three aspects of this lied enjoy been noticed as follows: (1) Antecedently substance wild in 1937, hanging on partary basic inedifice as exterior geological aggravatelook and hydrocarbon leakage, BPML companies precedeed 50 years of control and evolution act, control 176 polites in Delegate Said oilfield, unordered which are oil polites, accounting for 83%; 247 polites were dilled in Dart oilfield, and 161 were oil polites, accounting for 65%.
From sum and prosperity trounce of BPML control polites, it can be seen that the control prosperity trounce was very proud, indicating that the oil and gas reservoir-cap arrangement is fully preserved. 2) Pertain and Mobil bored two examination submerged polites, Delegate AAA and Delegate Bal 1970, and immodest examination polites, TTS-I, DOUR-I, TTS-I and Path-8 were bored by Pertain.
According to AD seismic facts from 1973,1974,1975,1978, there are merely a slender sum of seismic lines, liberal quantities of AD digital seismic were intensively unmoved in year 1985 and 1990, which instrument that merely Path-8 polite is the examination polite bored succeeding bulk of AD digital seismic; from dissection of seismic store and control interval, it is scheme that merely Path-8 polites used the AD digital seismic facts, which was one of merely two oil polites melody this determination (another polite is Delegate 81). 3) Dumelody 2006-2009, 13 outgrowth polites were bored in TTS, unordered which 9 were put into evolution as oil polites, retrogression control prosperity kindred of encircling 70%, durationliness in the output of encircling 4 darling barrels of undigested oil, polite DE-AAA was abundant in evolution and the furnish accounted for 50% , indicating that the area remains proud erection exigency and oil sources enjoy been incessantly supplemented.
From facts dissection of TTS geological studies, control scheme and control engineemelody and other aspects, it is settle that he ample geological con-aggravate does not regret the use of seismic facts and erect, stagnant clinging to the partary BPML determination geological aggravatelook, and numerous ingredients including wickedness option of control technology resulting careful defilement of the target flake by mud notwithstanding leaded to the consequences of low control prosperity kindred and the low oil and gas evolution.
But from the dissection of nigh polites retrogressionin the control interval of mm, DE-181 A could exlean massive oil and gas evolution inferior the event of merely decorous control technology, which instrument a vast immanent for resultant outgrowth for an old oilscene located nil . Km anticline composition, and retrogression 14. 98 darling barrels of undigested evolution antecedently the year 1937. The aggravate likenesss, although succeeding 130 years of examination and outgrowth, the deep evolution determination of Delegate Said Dart oilscene is stagnant the 50 years antecedently 1937, and the examination and outgrowth technology is proportionately lag succeeding.
With widely use of existent oil and gas examination and outgrowth as polite as control technology, the scene accomplish be serviceserviceable to create new discoveries and breakthroughs. In fresh months, PIPE has setup a functional technical team of oil and gas examination and outgrowth, through facts store, store, post- ordemelody dissection and examination of the oilscene geological, seismic, logging and other aspects, collectively retrogression facts dissection and precursive con-aggravate on control technology, polite exemplaring, and evolution act, the deep conclusions are as follows. 2.
Project Profile The Delegate said Dart Oilscene scheme a TACT (TECHNICAL ASSISTANCE CONTRACT) scheme ordinary by Pertain and TTS retrogression the end of oil revival and advancement of revival ingredient, the signal of the lessen is 20 years. Party A, Pertain, the exoteric oil posse of Indonesia; Deal-out B, P. T. TTS, a posse ordinary inferior Indonesian law, retrogression headquarters in Jakarta, who offers technical abettance for hydrocarbon examination. Dumelody the signal of the lessen, TTS may recaggravate 80% of its sieges from the sales acquisition of oil evolution in the primitive 3 years, and up to 65% in the succeeding years.
Of the retaining undigested oil succeeding require revival abatement, Pertain has straight to 73. 2143%, and TTS has straight to 26. 7857%. Having passed all approval procedures required by Indonesian Ministry of Energy and Mineral Instrument (SEEDS) and examines by authorities in attack of siege and law, PIPE was received by apt authorities of Indonesia to maintenance 100% shares of TTS and PIPE got actual licenses to precede petroleum examination and outgrowth activities in this kingdom.
Geographical and Structural Location The Delegate Said-Dart Oilscene is located in Pangolin Brendan, North Sumatra Province, Indonesia, km northwest from Media, km south from Pangolin Brendan-Pertain Oil Refinery and km Pangolin Us Oil Port respectively. The national deportment is very handy gone North Sumatra Highway instantly leads to the oilfield. (Fig. 1) Fig. L Location of Delegate Said Dart Oilscene The area inferior discourse is characterized by abrupt topography retrogression a apex eminence of less than 100 meters. The hollow where the oilfields were settle has an eminence of mm and the mean tallness of this area is mm.
Part of the area is adept by forests, durationliness the other negotiate-out has been converted into farms. The clime of this area is enthusiastic vaporous and rainy. The bulk of the oil polites are located in unreserved spaces of clumps of bushes. Straight now in the oilfield, all body roads are in cheerful-natured-natured provisions, durationliness the bypaths individualed retrogression polite sites are deeply destroyed. The oilscene is located in the southwestern negotiate-out of North Sumatra Basin, which is bounded on the west by defenseless pre-tertiary casts of Barista Mountains, on the south by Asana Dome, on the east by continental rejection of Strait of Malice, and on the north by Madman Sea Basin (Fig. ). The deep composition of the basin is located in Besetting- Delegate Said-Dart force anticline hem, a structural hem retrogression NW?SE trending axis and asymmetric flanks. Fig. Structural Location of Delegate Said Dart Geological Evaluation North Sumatra Basin is located in the northwestern tip of Sumatra Island, and extends northward to Madman Sea, retrogression a completion area of 13. 7x104km2. The onshore negotiate-out of the basin, which occupies merely 16% of the completion area, extends from coastal lowlands to sole of Barista Mountains.
Being classified as convergent-arc basin (according to Clammy), North Sumatra Basin is one of the most weighty hydrocarbon areas in Indonesia retrogression 3. 1 51st proven oil taciturnitys in locate and 6. 96x1011 mm proven gas taciturnitys in locate, completimerely 10. 1 laxest (oil equipollent), unordered which, the onshore oil taciturnitys are 2. 31st and gas taciturnitys are 6x1011 mm. The most valuserviceable Arrant Oilscene and Run Gasified are located in the north of Delegate Said Dart Oilfield. 3. Taciturnity Dissection Geological Reserves Evaluation 1.
Calculation Basis (1) Seismic casuistical structural sense, exemplar oil evolution facts, clear and cast proud- exigency visible parameters of effectatory dissection; (2) The old polite reservoir of oil and gas evolution facts , reservoir profoundness and the animalism parameters; (3) New polite control, logging, petrochemical, clear properties, oil and gas likenesss and other ramset's; (4) Collectively retrogression reservoir geological inferiorstandledge, scene outgrowth practices in tangible face, and the taciturnity forethought parameters succumb from other companies; 2.
Reserves Forethought Individual The deep reservoir of Delegate Said Dart oilfields is Upper Tertiary MOBS strata. According to the divergent oil-pliant provisions of reservoir, the reservoir of MOBS can be subdivided into 9 members (MOBS-O ? MOBS-8 ), in which the deep pliant erection is MOBS-2, stereographic animalism is encircling 50-80 meters and the net reservoir animalism is between 10-35 meters. For the other 8 reservoir erections, the proudness is proportionately slender, layer of taciturnitys is correspondingly slender, which can be used as immanent outgrowth reservoir.
Due to the emulation of old polite advice, the taciturnity forethought individual is bald to "Central Force Fold Belt" deep outgrowth flake series: MOBS-I, MOBS-2, MOBS-3, the forethought individual is likenessn in Tserviceable 1: Oilscene Outgrowth Flake Series Reservoir Top Profoundness (m) Reservoir Thickness(m) Delegate Said MOBS-I MOBS-2 1 WWW. 5 MOBS-3 >280 350 20 percent), senior register retrogression (>20 percent), or bald settle operability succeeding startup is aggravate 30 percent. The scarcity to meet and lay-open new scenes is intrusive the upstream sector to the extremes in signals of twain environment and technology.
For the senior western petroleum companies, there are few opportunities to take-out oil and gas retrogression minimal expose any longer. This is compounded by an toil-wide serviceable effect shortage. This shortage of serviceable effect appears to be having a negotiate-outicularly adverse impression on turnarounds (shutdowns) in the refinery sector. Settle turnarounds are the determinationic and prepared shutdown of facilities to accomplish deeptenance and/or invest new equipment. Figure 1 likenesss the act of 36 cent proud-complexity refinery turnarounds.
The mean register retrogression is past than 35% and the mean require aggravaterun is 25 percent. Perhaps past weightyly, there is a liberal limit of variability in the act as implied by the bars which value plus one and minus exemplar derangement. This instrument that the turnarounds are proudly unpredictable. As these trends gather momentum, exposes to scheme deed accomplish merely acception. The use and implementation of expose skill arrangements varies widely resisting the oil and gas toil. Techniques manage from partary spreadsheet inveterate arrangements to past pesticides enterprise-wide software arrangements.
For the most negotiate-out, scheme teams are identifying and tracking exposes. However, able quantification and implementation of defense delineations is failureing. Pristine Rated Risks in Oil and Gas Sector Inveterate on a factsbase of expose records we enjoy authorized what symbol of exposes twain scheme and turnaround teams are conformably rating as the most grave precedent to the deed rate. In completion, past than 25 expose records of diffemelody bulk and granularity enjoy been evaluated and nice to unearth the dominant sources of perceived scheme exposes in these sectors.
For the most negotiate-out, these teams used alike methodologies and tools to categorize schemes retrogressionin a despicable Expose Breakdown Composition (ORBS) as polite as an applicserviceable Act Breakdown Structures (WEBS). Individual scheme teams lean to subordinately conlean on their sense of expose categories and to which part retrogressionin the ORBS the expose should be allocated. To aggravatecome such failure, sundry basic and aggravatearching categories enjoy been introduced to restrain all exposes in a comparserviceable rank. Principal Projects This dissection is inveterate on nine senior oil and gas schemes.
The collectively sum of kiss authorized retrogressionin the reviewed expose records sumed to endured- eleven (1 1 1) succeeding eliminating entries that are too proud-level, unspecific, or may not limit retrogressionin the frameact of this con-over. Subsequently, nine basic categories, such as Market/Commercial, Technology, and Organizational enjoy been created to rank all competent exposes. Pursuant to the ranking, all categories enjoy been counted to particularize the rank-order, or precedentity of each condition retrogressionin the schemes expose framework. Technology cltangible topped the roll, followed by Planning/Schedule and then Organizational.
Project teams are conformably focused on ensumelody that technical specification and scheme issues are polite-defined precedent to the deed rate and lean to survey these issues as the ones retrogression the twain proudest verisimilitude of event and proudest impression. The pristine regret of these teams is to fix that there is tit interval to in the scheme specification faces to minimize the chances of past scheme changes dumelody constructive scheme or erection Tserviceable (1) - Scheme Expose Rating Rated in manage of Expose Severity RISK CATEGORY SUB-CATEGORIES 1 .
