UTILIZING ULTRASONIC AND PULSED-EDDY CURRENT TECHNOLOGIES TO MAP THE LOCATION OF FIBER-OPTIC CABLE AND CLAMPS: A CASE STUDY

In an ongoing attempt to learn more about subsurface conditions before and during production, service companies and operators have explored a wide range of technologies. One technology, that allows for transmission of subsurface data back to the surface, is the installment of fiber optic cable behind casing. Fiber optic cable not only provides subsurface data conditions affecting production, but it serves as a highway for data transmission in seismic surveys, as well as, monitoring production information itself along the entire length of the cable. We will expand on methods used to preserve this installment of the fiber optic cable by identifying its location behind casing. Circumferential ultrasonic scanning techniques have been used for many years to inspect the casing itself, and cement behind the first string of casing. These techniques offer a better inspection of channeling, or partial vertical void in cement behind first string of casing, than just your standard radial cement bond tool. Cement and Casing Inspection have been useful services of the ultrasonic scanning services, but it isn’t without limitations, whereas this scanning tool has a shallow depth of investigation. Traditionally, standard cement bond logs are used in conjunction with the circumferential ultrasonic scanning services to examine the bond index, and to offer some additional understanding of the cement bond to casing, as well as cement to formation bond. In that shallow ultrasonic scan, is where this publication will demonstrate the value added of locating the fiber optic cable, but it is not without some uncertainty. To reduce some of that uncertainty, a pulsed-eddy current system, which uses an arm-mounted pad sensor that contacts the inside of the first casing string, utilizes pulsed-eddy current technology to accurately locate the position of the fiber optic cable mounting clamps. Detecting the location of the clamps, offers great insight into oriented perforation, but as this publication will demonstrate, the fiber optic cable can meander in between those clamps. The circumferential ultrasonic scanning service offers visibility of the meandering of that fiber optic cable, in between clamps, and when used in combination with the pulsed-eddy current system, this creates an integrated service that reduces the probability of perforating the installment of the fiber optic cable. Purpose of this paper, will be, to demonstrate the use of the impedance data, gained from the circumferential ultrasonic scanning tool, in combination with the fiber optic clamp location from the pulsed-eddy current tool, to locate the fiber optic flatpack between clamp locations. However, there are limitations in the location of the fiber flatpack, as in, gaps between flatpack and casing, and/or lack of cement coverage. The final product will include the depth location of clamps, station degrees of fiber loop, degrees of fiber flatpack location, and level of confidence by interval shading. This information will give customers greater confidence in the execution of oriented perforation procedures, without damaging fiber optic cable flatpack.

PSX-29 Late-Breaking Abstract: The effectiveness of in vivo determination of meat quality using an ultrasonic scanning device in Kazakhstan

Improving beef quality is important task for livestock in Kazakhstan. Almost all indicators characterizing the quality of carcasses and beef are evaluated after slaughter. Their use in breeding is limited (Legoshin G.P. 2010). For lifetime assessment of carcasses in pedigree and slaughter cattle, Aloka 500B, EXAGO, EVO ultrasonographs are used, using which there is a high coincidence of the lifetime forecast of muscular development over the eye muscle area with the indicator in carcasses after slaughter of animals (Bisembaev A.T. 2019). A high correlation of prognosis of ribeye area with live weight of animals was noted (Lisitsyn A.B. 2010). The aim of the project is to study the effectiveness of in vivo determination of meat quality using an ultrasonic scanning device. Tasks: to determine the ribeye area, the fat of the cattle using an EXAGO ultrasonograph; compare the ribeye area, the fat of the slaughter cattle, determined using an EXAGO ultrasonograph and measured on the carcass after slaughter. The studies were carried out on pedigree bull-calves of the Kazakh white head (85 animals), Auliekol (101 animals) breeds aged 14–15 months and on the feeding stock (6 animals) with a live weight of more than 943 lb. The ribeye area, the fat were obtained: Kazakh white head had 23.2 sq.in and 0.10 in, Auliekol – 20.4 sq.in and 0.09 in. The animals studied after slaughter yielded full-bodied carcasses, while the slaughter yield averaged 56.3%. The correlation between live weight level and ribeye was r=0.97. The coincidence of ribeye, measured by an ultrasonograph with a post-mortem measurement averaging 93.8%. The introduction of ultrasound methods for determining beef productivity in beef industry will allow livestock husbandry to become cost-effective and improve the beef quality. The results of ultrasound images for the carcass traits will be applied in selection and breeding work.
