Karstification process occurs as a result of dissolution on limestone lithology formed in typical morphology of caves, rounded or elongated pits and conical hills. This also related with structural pattern that also intesively occurs at western part of Buton Island. Research area located at lattitude 5027’0” S – 5032’0’’ S and longitude 122049’30” E - 122052’30” E. Purpose of this research was to identified karst landscape and karstificatiom process on Wapulaka Formation and recognize the structural pattern on this formation. By using field observation and SRTM data interpretation we considered that karst formations formed on Wapulaka Formation was Quarter limestone which diagenesis process of dissolution forming karst landform also related with uplifted event at pliocene – pleistocene. This formed related with complex interaction between the geology, climate, hydrology and biological factors that created various landscape morphology such as caves, underground river, stalagtite, stalagmite and others cave ornament.

From year to year the number of oil production will be reduced and the amount of water production will grow, so will cause problems in managing the water. Some of the problems that arise are limitations in the surface water treatment systems, the availability of water treatment chemicals, and declining well productivity. Doing some work over to lower the value of water production and increase the value of oil production, one of which is the partial water shut off. On the hawa field, some job well done partial water shut off. The results of such work nothing works and nothing failed. Analysis performed on the job partial water shut off with the observation of the historycompletion and the processing of data and calculation of the value of production history OOIP to get the value of remaining reserves. After analysis, it was found some causes of work partial water shut off the well would be successful if it fulfills several criteria such as: the value of remaining reserves are still large enough, she had never done work partial water shut off in the layer and selecting the type of isolation right tool. While the cause of such failures is that the well had done work partial water shut off the same perforation interval. The criteria are very important and necessary in deciding the work partial water shut off the a better well done or not.

Material Management has always been a major challenge in the world of industry, especially the world of gas transportation. Poor on material planning, limitationon material supply the length of lead time delivery of materials is often a major constraint on the operational productivity. The obligation to maintain the reliability of the instrument to ensure smooth gas supply to consumers remains to be one of the challenges in maintaining productivity. These efforts will not be successful if the company is not able to increase the flexibility of the material supply chain. Not Providing Information Regarding Details Material stock, remoteness Distance Between warehouse and Station, Not Providing Information Details on stock Material, remoteness Distance Between warehouse and Station, and manual data collection worsen the problem tha couldt cause the error on calculating material stock, moreover the problem become more complicated by the lack of collaboration of material information that should be known by the user as the material user on field and planners as a warehouse supervisor. One solution to the problem is to develop the Material Traceabillity Strategy- A technology that can replace manual data entry process that still use paper as a recording media, allows personnel to track and manage the material in real time, Improve Information Sharing among divisions. This paper will discuss the problems and solutions that are applied in order to improve the reliability of materials that can improve supply chain collaboration in the handling of the material. This paper emphasizes the importance of the revolution in material handling in oil & gas transportation company that has been applied and proved successful in PT. Pertamina Gas Eastern Java Operation Area.

Analisis Potensi Daya Listrik Pada Sumur Produksi Panas Bumi Dengan Mengunakan Metode Back Pressure Pada Unit XY Rycha Melysa; Fitrianti Fitrianti

As the increasing demand of energy in indonesia, PT.Pertamina Geothermal Energy area Kamojang that is one of the companies which are engaged in geothermal power plant which contributed the need for electricity domestic with a total capacity of 235 MW with consisting of 5 units of steam power plants electricity.But to produce the electrical power needs to be done a calculation about the potential electrical power for every production wells, so it is necessary to do back pressure production test for every production wells.Back pressure production test was conducted to obtain capability of geothermal production well, it is necessary to know the output curve of well production , back pressureproductionproduction test done by closing the wells first untill wellhead pressure reach a stability and then produce well with setting wellhead pressure at different wellhead pressure until it achieve stability for each setting of the wellhead pressure.The result of back pressure production test for every production wells in unit “XY” that the maximum mass flowof XY-1, XY-2, XY-3, and XY-4 wells at 10 kg/cm² are 28,49 tons/hour, 103,72 tons/hour, 175,31 tons/hour and 68,97 tons/hour. So the maximum potential for unit “XY” is 50 MW with total mass flow is about 373,04 kg/cm².

The cementing process can determine successful oil well when producing oil to the surface. Planning the time required for the cement suspension to achieve consistency of 100 UC (unit of consistency) or thickening time and the maximum limit of water content used is the nature of cement slurry that affect the quality of cement. The addition of coconut shell charcoal with variation of heating temperature 400 0C, 500 0C, 600 0C, 700 0C, 800 0C, 900 0C to the basic cement was done in this study to determine the effect of heating temperature of coconut shell charcoal to thickening time and free water cement drilling. This experimental study uses an additive material derived from coconut shell charcoal. This experiment begins by preparing a cement sample with a coconut shell charcoal concentration of 1%. The coconut shell charcoal used has different heating temperatures of 400 0C, 500 0C, 600 0C, 700 0C, 800 0C, 900 0C. Suspense cement is made by mixing G grade cement, water, bentonite, CaCl2 and coconut shell charcoal. Thickening time test using atmospheric equipment consistometer and measuring cups used to determine the value of free water. The results showed that the thickening time and free water values were influenced by the heating temperature of coconut shell charcoal. The higher coconut shell charcoal temperature used in the cement suspension make thickening time of the cement suspension becomes shorter. The optimum heating temperature of coconut shell charcoal is 700 0C with thickening time of 1 hour 38 seconds 52 seconds and free water 1.2 mL.
