High quality X-Y density data in deviated wellbores in New Zealand

Recorded in an 8.5” deviated wellbore in New Zealand, at up to 52deg deviation. 9 Tool Taxis provided an optimum positioning of all sensors of the Quad-Combo/Dual- Density toolstring. They also reduced the drag to a minimum and oriented the bottom Guide upwards in order to navigate to TD past the multiple borehole breakouts. A modified flex-joint connected the two Density tools, with the measuring skids aligned perpendicular to each other. The lower Y-Density tool was oriented to record density on the low side of the wellbore. Petromac Centering Taxis perfectly centralized the upper X-Density tool in the borehole so that the density skid made perfect contact with the wellbore wall when it was opened. Petromac Wireline Express enables cross density measurement. 0.1 0.05 0.02 0.02 0.05 0.1
