Total methane content in the atmosphere has increased for two times during last two hundred years. Since 1900s, the annual rate of growth for methane dramatically increased. The sources of methane emissions to the air are their storage reservoirs, different oil-gas refineries, main pipelines and their transport facilities as well. A new method for detection of methane escape from the main pipelines has been developed and the order of its realization shown. Mathematic algorithm of the method is presented and the calculation formula for optical thickness of methane over the track obtained. Obtained formula allows diagnosing the escapes in gas pipelines distantly. Block-scheme of operation algorithm of the realization of offered method has been developed as well.

Simulation Results

The real thermal parameters always have inevitable influence on the simulation results of the structure thermal field and stress field in the construction of mass concrete. A new measuring and calculation method for concrete thermal conductivity was put forward. Eight or six sensor points measuring method and calculation formula are present, and the latter is the simplification of the former. Comparing the real thermal conductivity with the calculation result by the new method, it can be seen that the thermal conductivity can be obtained within about 6 day’s age at site and with the accurate degree of 98%. The new method will provide an efficient way for the concrete structure researcher and designer.

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.

Testing Protocol

In this article, a new testing equipment and protocol in order to evaluate acid gas scavengers for direct chemical injection into gas pipelines is described. The testing protocol address several shortcomings in previous accepted tests which did not take into account the formation of a spray of the product, or tested the product in its final formulation.
