JFAR publishes report on climate change science for actuaries LNB News 01/01/0001 2871 Acoustic logs do not measure cement quality directly, rather, this value is inferred from the degree of acoustic coupling of the cement to the casing and to the formation. Properly run and interpreted, cement-bond logs (CBL) provide highly reliable estimates of well integrity and zone isolation. Just as … See more Early CBL designs (1960s) used a single transmitter and single receiver for an amplitude measurement. In an evolution similar to that of openhole acoustic logs, new designs were subsequently introduced that … See more Ultrasonic tools can be operated to address two objectives concurrently: casing integrity and cement evaluation. A further example is … See more Radial-cement-evaluation devices were developed to overcome some limitations of conventional cement-bond tools and to permit more accurate … See more Conventional cement-bond logs (CBLs) comprise a pulsed transmitter and several receivers of acoustic energy positioned as a vertical array of … See more

WebApr 14, 2024 · The need to evaluate cement behind multiple casing strings has become critical for well P&A or slot recovery. This technical paper discusses how P&A operations can be optimized in offshore applications using Epilogue dual-string barrier evaluation technology to reduce the costs associated with rig time and potentially the unnecessary … WebA cement bond log measures the integrity of the cement bond and is obtained using sonic tools which measure the amplitude of sound pulses from the transmitter to the receiver. The acoustic signal travels down the casing wall in between a transmitter and receiver. fashion nova plus size long dresses

WebJul 4, 2024 · It’s just a common sense, step-by-step approach in interpreting any well logs. But the results are magical.This is a technique I called ‘The Ko Ko Rules’. To make it work, you need to have Gamma Ray Log, Resistivity Logs, Density and Neutron logs plotted on the same log plot respectively. Then, by looking at how the curve deflects ... WebDec 6, 2015 · It will indicate that cement bond and cement evaluation logs play an important role in identifying possible well integrity issues, which can result from poor … WebThe shear and Stoneley waves are visible even if there is poor cement bond, but the annulus must be full of cement. In addition, the tool can provide all standard measurements of the existing open hole sonic tools including short and long spaced BHCS logs and cement bond logs. fashion nova plus size haul
