Cause of Lapindo Hut Mud Flood Case
Civics Individual Paper OVERCOMING PT.LAPINDO BRANTAS HOT MUD CASE

By: Aditya Rahman Sulaiman 10/HK/295884/19279 International Undergraduate Programme Lapindo hot mud flood case or we usually called it “banjir lumpur panas Lapindo” is an event of the unstoppable mud gush in Kecamatan Porong, Kabupaten Sidoarjo, Jawa Timur and this accident have been happened since 29 may 2006. There are 2 views of the cause of this Lapindo hut mud flood case. First, some scholars said that the primary cause of this event was because drilling mistakes and technical problems. Other theory said that it was happened because natural disaster, this theory explaining that sooner or later hot mud gush will be arise, the lapindo’s mining activity is only the trigger.
First theory believes that there is an eror in the mining activity, PT.LAPINDO is suspected not doing a proper procedure in using the correct brace and bit (mata bor), they use it within different depth which has different thickness and causing a fault. In the begininning, PT LAPINDO won a drilling well tender called “pengeboran sumur Banjar Panji-1” from PT Medici Citra Nusantara as worth as US$24 million. PT LAPINDO was planning to drill the well until 8500 feet or 2590 meter depth. In order to reach that depth, infiltrate the Kujung layer (lapisan batu gamping), anticipate circulation loss potency (losing mud from the formation cause a high density liquid or mud come up) and kick potency (infiltration of other fluide to the upper layer), normally PT LAPINDO is needed to use a casing for its brace and bit. Running their work, PT LAPINDO has already used 30 inch casing for 150 feet depth, 20 inch casing for 1195 feet, 16 inch casing for 2385 feet and casing 13-3/8 inch for 3580 feet until 9297 feet, they only not yet put the last casing, the 9-5/8 inch casing for reach the Kujung layer in 8500 feet. The fact is, PT LAPINDO has a wrong prognosis a drilling term which briefly means drilling method of

    Judicial Review

    The controversy of judicial review which at extreme points, is called judicial activism, is a concept new to India. Judicial review can be defined as the judiciary, in the exercise of its own independence, checking and cross checking the working of the other organs of the government, while trying to uphold the ideal of ‘the rule of law’. Judicial activism more reformist in character is often confused with judicial review. According to Black’s Law Dictionary, judicial activism is “a philosophy of judicial decision-making whereby judges allow their personal views about public policy, among other factors, to guide their decisions, usually with the suggestion that adherents of this philosophy tend to find constitutional violations and are willing to ignore precedent.”However, due to the frequent misreading of the two terms, this article will only refer to judicial review as a proportionate mixture of the two.…

    I believe that we should focus on other ways of getting energy besides drilling, especially off shore. We all have seen what can happen if something go wrong when we drill off shore. I don’t feel that we know enough information about drilling deep water. According to Margolis, “ water pressure at those depths is more than 200 times that of the atmosphere at the surface, and no one knew what all the heat, gas, and salt below the seafloor might do to the drilling equipment”(Margolis, 2010, para.). If the pressure was too great and the right precautions not taken, the well could have blown and even set the drill platform on fire, Bueno recalls. After more than a year of drilling, they had hit nothing” (Margolis, 2010, para.).…

    In this research, the researcher will elaborate the accident which happened in 2011, Bohai Bay, China, where a China government controlled company, namely, China National Offshore Oil Company cooperates with a US-based company, ConocoPhillips to explore and drill oil. In the project, the two companies collaborating, the CNOOC accounts for 51% of the shares, and CONOCOPHILLPS accounts for 49% of it, whereas the minority, CONOCOPHILLPS, is responsible for conducting the real exploration and development. Unfortunately, in late June, 2011, some oil trace was discovered on the sea surface near the No.19-3 marine drilling platform in Bohai Bay. And the following information also proved that the 19-3 marine drilling platform was leaking the oil into the sea, while the amount of the leak oil kept increasing. The government had urged CONOCOPHILLPS and CNOOC to prevent the oil leaking into the sea water, while both of the companies did not prevent the tendency successfully. What is worse, the new leak point was kept being discovered in the following months. During this period the report that came after another…

    The safety steps included in this process are aimed to protect water supplies to be used by the population and to assure that neither the fluid that will be pumped through the well, nor the oil or gas that will eventually be gathered enters in contact with the water sources designated for the human consumption. To comply with these regulations steel surface or intermediate casings are interleaved into the well to depths of between 1,000 and 4,000 feet. The space between these casing “strings” and the drilled hole (wellbore), called the annulus, and is filling up with cement. Once the cement has been set, the drilling continues from the bottom of the surface or intermediate cemented steel casing to the next depth. This process is repeated, using smaller steel casing each time, until the oil and gas-bearing reservoir is finally reached (generally 6,000 to 10,000 ft).…

    Mud Density

    • 370 Words
    • 1 Page

    Mud weight otherwise known as drilling fluid density is a very important property of the drilling fluid which must be determined regularly during the drilling process. It is defined as the weight per unit volume of the drilling fluid or drilling mud usually expressed in units of g/cm3 or more conveniently lb/gal. Drilling fluid density or mud weight must be measured at regular intervals of the drilling process because as different formations are encountered during the drilling process, different fluids and substances are released by those formations into the drilling fluids which alter the density of the mud. In many cases, if these variations in mud weight are not controlled (which can only be known by checking the mud regularly), hazards such as loss of circulation and potential blowouts can be risked. But by regularly checking on the mud weight, those risks mentioned above can be prevented from occurring. Since the hydrostatic pressure of the mud depends directly on the density of the fluid and if the hydrostatic pressure is much greater than the formation pressure, it can lead to the losing of the continuous phase (liquid phase) of the drilling fluid to the porous formations (loss circulation). Conversely if the hydrostatic pressure of the drilling fluid is less than the pressures of the formations encountered, this can lead to the gushing of the formation fluids into the drilled wellbore which if not properly checked, can lead to blowout (the most dangerous hazard in drilling). The aims and objectives of this experiment were to determine. n. [Drilling Fluids]…

    Boring ashore is an immense extend in itself in addition to endeavoring to penetrate a mile under unpleasant oceans in a dark pit. Seaward boring is a serious and perilous process that takes exactness and time. Oil wells are regularly high rise size articles many feet beneath the surface. They are greatly mind boggling structures and the scarcest misstep might be annihilating to nature 's turf. When boring can start, exploratory wells are situated up to discover the accurate oil gushers. When a spot is found with a sufficient measure of oil, a subsea boring format is placed set up to guide out where the parts of the well ought to be spotted. In the following step, a drill string, which join from the beginning the stage, is utilized to make gaps in the sea depths. At the point when the opening is profound enough, metal channel packaging is situated up around the dividers of the gap to stabilize it. Finally, a conductor funnel is placed set up to keep spillage from the openings. When petroleum is hit, preparation packaging is established to permit the oil to be pumped to the surface.

    Well Completion Tubing

    17C-1 The Lease Pumper’s Handbook Chapter 17 Well Servicing and Workover Section C THE TUBING STRING C-1. Tubing and Casing Perforation. The relationship of casing perforations to tubing perforations is important to the performance of the well, whether it is a flowing well or produced by artificial lift. The lease operator must know if the tubing perforations are above or below the casing perforations or at the same level (Figure 1). This can be critical as to how much oil the well produces and the problems encountered. For wells that produce a lot of scale, production personnel operate under different philosophies. One school of thought is that the higher the tubing perforations can be raised above the casing perforations and still achieve a satisfactory daily production, the less the scale will break out of the water in the tubing and flow line. Some companies raise the tubing perforations a few feet above the casing perforations, while other companies move them much higher. Some operators maintain that if tubing perforations are placed even with or lower than the casing perforations, the reduction in reservoir pressure will increase daily production, resulting in increased income to solve the additional production problems. Other companies place the tubing perforations below the casing perforations even if it results in a tubing arrangement where the tubing has no mud anchor. A shop-made two-foot perforated joint is used. The joint is closed on bottom and has dozens of ½-inch holes drilled into it. A collar is used to screw it directly under the seating nipple. This reduces the length of the pump gas anchor to one foot or less. Companies favoring this method maintain that it gives the highest daily average production. The most typical tubing arrangement is to place the tubing perforations a few feet above the casing perforations. This maintains a small amount of liquid against the formation, instead of having a drained or dry matrix area at the bottom of the…
