Abstract

I et boresystem for boring av en brønn fra en overflateposisjon blir hydraulisk kalibrering utført ved å ta et antall hydrauliske kalibreringsmålinger der hver hydraulisk kalibreringsmåling blir tatt ved en respektiv borestreng-RPM og strøm- ningshastighet innenfor et hydraulisk kalibreringsområde. En hydraulisk basislinje- funksjon blir så bestemt som forutsier, innenfor en forutbestemt nøyaktighetsgrad, hver av antallet hydrauliske kalibreringsmålinger.
