The dynamic change of the bottom-hole pressure
tested is always susceptible to the wellbore storage effect.
A step change in well operability has been realised through the combination of real-time bottom-hole pressure
data from the ESP and the surface equipment Strike designed and built to take into account lessons learned from Klebb 1.
In each production scenario the bottom-hole pressure
will be set above the bubble point pressure and the reservoir will be always undersaturated.
Meaningful and realistic data was retrieved from this environment for the first time and downloaded from the returned microchip that showed the dynamic bottom-hole pressure
of 7,500 psi and circulating bottom hole temperature of 190 degrees Fahrenheit, consistent with static bottom hole pressure of 6,700 psi due to mud weight and wireline tool recorded static bottom hole temperature at 235 degrees.
Faulkner added, "The initial bottom-hole pressure
is coming in at 9000 psi and both existing fracs are intact and not watered out.
Johnny Edwards, President of Energy Resource Technology GOM (ERT), a wholly owned subsidiary of Helix, stated, "Preliminary data from down-hole test tools confirmed oil in the Wang well with over 11,800 psi of bottom-hole pressure
Johnny Edwards, President of Energy Resource Technology GOM (ERT), a wholly-owned subsidiary of Helix, stated, "Preliminary data from down-hole test tools confirmed oil in the Danny II well with over 9,500 psi of bottom-hole pressure
MPO's Total Control Driller ("TCD") is an advanced MPD system that maintains constant bottom-hole pressure
to mitigate many drilling hazards.
At this time, the oil and gas flow rate would be expected to increase substantially due to the lower flowing bottom-hole pressure
Part of the West Koynare structure of the Lower Triassic Alexandrovo formation, the well has also recorded the highest bottom-hole pressure
encountered in the country, measuring 11,500psi, as well as recording low sulphur content.
Shut-in casing and tubing pressures are 2,600 psi, indicating virgin bottom-hole pressure
Calliope can achieve substantially lower flowing bottom-hole pressure
than conventional production methods because it does not rely on reservoir pressure to lift liquids.
