Фиктивный эффект, которым иногда объясняют аномальный подъем давления при испытании герметичности скважины давлением
(в частности, объяснение персонала, приведшее к переоценке качества цементажа и к аварии Deepwater Horizon - http://ru.wikipedia.org/wiki/Взрыв_нефтяной_платформы_«Deepw... )

They believed that what they were seeing was a bladder effect.
We do not need to know anything about the bladder effect theory, except to say it had no merit. Professional engineers have subsequently said that this is a theory without any basis. But the drillers were convinced of the validity of their theory and concluded that the rise in pressure was due to the bladder effect, not due to the failure of the well to seal.

He was teased into agreeing and in the end he accepted the view of the drillers that it was reasonable to see the pressure rising in this situation because of the bladder effect.
