Pipeline External Corrosion Protection

Paper Id: 17 [Abstract]

The protection of pipelines from external corrosion is commonly accomplished by the combination of pipeline coatings with cathodic protection, to protect those portions of the pipeline that are inadequately coated or where the coating contains defects. Defects in pipeline coatings that expose bare steel are termed holidays. Conventional anode resistance formulas that ignore the current and potential distribution on the pipes are inadequate for the modelling of pipelines with holidays. Current and potential distribution must also be considered when modelling multiple pipelines. Factors such as variations in coating quality and stray current interference have an effect on the quality of the cathodic protection system. Another major factor in the design and maintenance of the underground infrastructure (e.g. pipelines, storage tanks, tunnels etc) is the electrical interference (electrical pollution) from power lines, railways and other electrical sources. Traditional resistance formulas are inadequate in modelling these complex interactions. Pipes with coated surfaces can be modelled in several ways. It was assumed in the analysis that the coating is a highly resistive barrier.

Matrix Acid Stimulation

Paper Id: 18 [Abstract]

Matrix acid stimulation is a relatively simple technique that is one of the most cost-effective methods to enhance well productivity and improve hydrocarbon recovery. Carbonate acidizing is usually performed with HCL except in situations where temperatures are very high and corrosion is an issue. Acids attack steel to produce solutions of iron salts while generating hydrogen gas. Over the years, many different acidizing systems have been developed for specific applications.<br />Matrix acidizing, with the appropriate systems in correctly identified candidate wells, is the most cost-effective way to enhance oil production in sandstone and carbonate reservoirs. Increased understanding of the chemistry and physics of the acidizing process as well as improvements in well site implementation have resulted in better acidizing success. Use of computer software that includes all known rules and guidelines for sandstone acidizing can greatly improve the success ratio by eliminating inappropriate designs and standardizing treatments. New acid systems with improved performance were developed specifically to address many of the problems inherent in sandstone acidizing.

Enhancing Condensate Recovery from Gas Condensate Reservoirs through Gas Injection
Abdollah Esmaeili¹ ; Yermek Aubakirov¹ ; Fatima Kanapiyeva¹ ; ¹Al-Farabi Kazakh National University, Almaty, Kazakhstan;
Paper Id: 16 [Abstract]

Gas reservoirs can be classified into dry gas reservoirs, wet gas reservoirs and Gas condensate reservoirs. In gas condensate reservoirs, the reservoir temperature lies between the critical temperature and the cricondentherm. The gas will drop out liquid by retrograde condensation in the reservoir, when the pressure falls below the dew point. This heavy part of the gas has found many application in industry and also in daily life and by remaining in reservoir not only this valuable liquid is lost but also its accumulation will result in forming a condensate bank near the well bore region which makes a considerable reduction in well productivity.<br />In this paper, gas injection will be studied in a gas condensate reservoir to increase the recovery factor moreover the capability of different injection gases (CO2, N2, CH4 and separator gas) will be compared through different injection schemes. The injection schemes which will be considered are: different injection rates, different injection pressures and different injection durations. We think that the response of the reservoir in different cases will be different but that injection of all of them can increase the condensate recovery. As many parameters can affect the decision of selecting the injection scheme, other than the gas and condensate recovery factor, doing an economical evaluation is inevitable to take them all into account and determine the best one. <br />In this paper, the efficiency of different schemes of gas injection and gas recycling in condensate recovery from a gas condensate reservoir, through compositional simulation has been studied and compared. The effect of changing injection rate, injection pressure and injection duration has been investigated by three injection gases (N2, CO2, CH4) and gas recycling. The appropriate and optimum case can be selected considering the results of the simulation work and doing an economical evaluation, taking into account all the parameters such as: the price of the gas and condensate, the price of the injection gases and the cost of the facilities needed in each scheme with regard to the present level.

Oil Production and Environmental Damage
Abdollah Esmaeili¹ ; Yermek Aubakirov¹ ; Fatima Kanapiyeva¹ ; ¹Al-Farabi Kazakh National University, Almaty, Kazakhstan;
Paper Id: 19 [Abstract]

Most countries depend on oil. States will go to great lengths to acquire an oil production capability or to be assured access to the free flow of oil. History has provided several examples in which states were willing to go to war to obtain oil resources or in defense of an oil producing region. States have even become involved in conflicts over areas which may only possibly contain oil resources. This trend is likely to continue in the future until a more economical resource is discovered or until the world's oil wells run dry. One problem associated with this dependence on oil is the extremely damaging effects that production, distribution, and use have on the environment. Furthermore, accidents and conflict can disrupt production or the actual oil resource, which can also result in environmental devastation. One potential solution to this problem is to devise a more environmentally-safe resource to fuel the economies of the world.
