ATCO Commercial Division initiated a novel method of tube string protection approximately two years ago. This was a method of lining the tubes for oil, gas and water wells to prevent deterioration from corrosive elements with the medium being pumped through the well. These fluids and gases often contain high concentrations of Hydrogen Sulphide at very high temperatures.
The methods used in the past for overcoming this corrosion have either involved the use of exotic and therefore expensive well tubes, or internal pipe coating which can be subject to damage and therefore increased corrosion during workovers on the wells.
ATCO Commercial Division introduced Saudi Aramco to Duoline, manufactured by Maxtube, which is a pre-formed GRE (Glass Reinforced Epoxy) well liner, tolerant to extremely high temperatures and high concentrations of H2S and other corrosive materials. It inserted inside the tubing before the tubing is strung down the well.
As an experiment, we lined the tubing of three wells, which had previously been giving Saudi Aramco severe problems during workovers and wire line work because of harsh corrosion to the tubing resulting in many tubing pulls.
These wells have now been in operation for almost two years and Saudi Aramco have had no problems whatsoever during workovers and wireline work. We have now been asked by Saudi Aramco to provide them with pricing for the lining of a further three wells, all in the Berri Field, which we feel confident we will be successful in receiving the order for with more to come.
The success of this initiative has been the result of the efforts of one of the sales engineers in the Commercial Division, Fadhel Al Hashem, who despite being told by Saudi Aramco that they would insist upon a minimum of two full years successful operation for the original wells before the product would be approved for use, persevered with project, continually checking with the various engineers and departments involved within Saudi Aramco, to bring this to the position in which it is in today. Congratulations Fadhel
