That may be a bad assumption.<br /><br />Remember the fluid flow model studies Halliburton did before recommending the 20 centralizers? Without all those centralizers, the pipe would be slightly off center and there were predicted to be channels in the cement. We can thank the cost-shaving organization for which former CEO Tony Hayward has yet to pay the full price, but BP went with the 6 centralizers in hand.<br /><br />Probably, the cement sheath has channels through it.Kinuachdrachhttps://www.blogger.com/profile/13275320683766290581noreply@blogger.com
