Technology Vivid Acoustic Logging applies to most well conditions and measures various leaks and flow behind casing. As long as leaks or flows behind casings are there, VIVID will find it. Deployed via E-line or slickline, VIVID can RIH thru tubing without well kill or tubing change. In one trip, VIVID is able to precisely locate leaks in tubing, GLVs, SSSV, CIV, Packers, Production casing, Intermediate casing, surface casing and conductor pipes. A sequence of pressure bleed off and build up is only necessary in A/B/C wellhead valve to locate all the leaks and flow behind casings. Even in some cases pressure bleed off is difficult, VIVID will only require a min. of 50 psi bleed down or 2-3 psi/hr pressure drop to secure a success activate the leak or flow to be detected by VIVID sensors. Flow behind casing can be measured to find source either from formation or shallow even for gas bubble flow. Application VIVID has served many oil companies such as Petronas, Shell, Chevron and provided accurate data to help clients save a great deal of time and money. |
