The  Oil  &  Gas  industry  has  grown  and  new  discoveries  and  technologies  have  risen  in  order  to  accommodate  the  dynamics   of  such  industry.  With  investments  ranging  billions  of  US  Dollars  is  mandatory  to  create  measures  to  avoid  pressure  vs   temperature  related  issues  during  the  extraction,  transportation  and  of  the  crude  in  order  to  minimize  losses  and  maximize   the  profit  (Borsani,  2001).  Hydrates  in  oil&  gas  pipelines  poses  a  very  big  issue  to  the  industry.  Hydrates  are  normally  formed   when  the  adequate  conditions  (gas,  water,  compatible  pressures  and  temperature  ranges)  are  present.  They  are  in  the   market  several  methodologies  to  prevent  the  evolution  or  emerging  of  hydrates.  An  adequate  thermal  study  during  the   design  of  the  pipeline  and  its  insulation  layers,  constitutes  a  greater  value  on  the  path  to  avoid  hydrates  formation  during   the  pipeline  operating  life.  On  This  paper  the  study  is  dedicated  on  the  impact  of  thermal  analysis  in  one  of  the  pipelines   operating  in  one  of  the  Angolans  Offshore  fields.  COSMOS  Geostar  is  the  tool  used  for  the  investigation.  The  study  was   conducted  in  a  pipeline  considering  the  thermal  conduction  through  a  normal  pipe  section  and  the  thermal  conduction   through  a  field  joint.  This  project  has  proven  the  efficiency  of  COSMOS  in  assisting  on  the  determination  of  a  proper  type,   nature  and  size  of  insulation  to  be  applied  in  a  certain  piping  system  for  crude  oil  production  and/or  transport.

The National Energy Board (NEB) is a Canadian federal regulatory agency whose mandate under the NEB Act is to regulate the construction and operation of interprovincial and international oil, gas and commodity pipelines; the construction and operation of international and designated interprovincial power lines; the setting of tolls and tariffs for oil and gas pipelines under its jurisdiction; the export of oil, natural gas and electricity, and the import of natural gas. International and interprovincial pipelines are subject to the statutory requirements of the NEB Act and Regulations made by the NEB. The regulations typically incorporate consensus standards such as the Canadian Standards Association (CSA Z662 - Oil and Gas Pipeline Systems). The NEB tracks and monitors compliance to ensure that companies fulfill the requirements of the Act and Regulations as well as any conditions imposed at the time of approval of the facilities. In carrying out its mandate, the NEB promotes the safety of people, the protection of property and the environment, and economic efficiency in the Canadian public interest. Recently, the NEB has implemented a formal system to track and monitor compliance. In approving new projects, the NEB imposes conditions outlined in approval Orders and Certificates. It then tracks these conditions for compliance, completeness and effectiveness. The compliance information is gathered mainly from activities such as inspections, audits and company filings. This paper explores in greater detail the NEB’s role in terms of tracking and monitoring compliance, NEB expectations of regulated companies and the effectiveness of a self-reporting condition. It also discusses the advantages for companies to be in compliance and its importance.

Corrosion Defects

Corrosion is considered as one of the most predominant causes of pipeline failures in the oil and gas industry and normally cannot be easily detected at the inner surface of pipelines without service disruption. The real-time inspection of oil and gas pipelines is extremely vital to mitigate accidents and maintenance cost as well as to improve the oil and gas transport efficiency. In this paper, a new, non-contact optical sensor array method for real-time inspection and non-destructive evaluation (NDE) of pipelines is presented. The proposed optical method consists of light emitting diodes (LEDs) and light dependent resistors (LDRs) to send light and receive reflected light from the inner surface of pipelines. The uniqueness of the proposed method lies in its accurate detection as well as its localization of corrosion defects, based on the utilization of optical sensor array in the pipeline, and also the flexibility with which this system can be adopted for pipelines with different services, sizes, and materials, as well as the method’s economic viability. Experimental studies are conducted considering corrosion defects with different features and dimensions to confirm the robustness and accuracy of the method. The obtained data are processed with discrete wavelet transform (DWT) for noise cancelation and feature extraction. The estimated sizes of the corrosion defects for different physical parameters, such as inspection speed and lift-off distance, are investigated and, finally, some preliminary tests are conducted based on the implementation of the proposed method on an in-line developed smart pipeline inspection gauge (PIG) for in-line inspection (ILI) application, with resulting success.
