... operation was successful relative to prior attempts with conventional methods. The intersect and following abandonment process were not completed without lessons learned. Hole conditions, an up-hole casing exit junction, and custom cement blends were a few of the areas of focus for future improvement...

... Abstract Oilfield cements have been an integral part of any drilling operation and forms the primary barrier when it comes to ensuring wellbore integrity. The strength of the cement layer is one of the primary factors that confirms the success of the drilling job and ensures the well remains...

... Abstract Well construction typically involves cementing a casing placed in the well in order to support the casing and isolate it from the surrounding formation and fluids. For oil and gas wells, well integrity is a critical issue that can affect safety and productivity throughout the life...

...Sedimentation Test The sedimentation test needs newly mixed cement slurry to be placed within a tube with a diameter of 25 mm and a length of 200 mm ( Figure 5 ). The slurry-prepared samples are placed in the tube. To avoid evaporation, a top cover is put on the test tube, and the sample...

...Challenges Another advantage of using resin-blended cement is higher resistivity in sour gas environments. It has been proven that long-term exposure of CO 2 and H 2 S on epoxy resin has minimal impact to the overall integrity of epoxy resin ( Wang et al. 2021 ). Thus, resin-blended cement...

... can be described, with quantitative estimation of borehole enlargement, outer casing deformation, etc. With the amplitude of the TIE, it is possible to get an image sensitive to the acoustic properties of the formation, especially in the case of a cement filled annulus when the impedance contrast...

... undertake. Well abandonment normally involves setting barrier plugs at critical intervals to prevent the wellbore from becoming a conduit for fluid migration ( API Bull E3, 2018 ). Most, if not all regulations and recommended practices are built around cement, its placement, minimum lengths, and ways...

... Well integrity is very important for well operation in oil and gas industry. Advanced technologies and analyses have been developed to ensure well integrity. One of the most important analysis to be done is the evaluation of the cement bond which measures the presence and bonding of cement...

... Abstract In this study, commercially available styrene butadiene rubber (SBR) polymer up to 3% was added to the highly sensing chemo-thermo-piezoresistive smart cement with a water-to-cement ratio of 0.38 to investigate the effects on the sensing properties. Series of quality control, curing...

... Abstract Well abandonment is often not thought of as a crucial part of a well's life. As such, traditional methods of abandoning a well utilizing cement and bridge plugs are still common practice among most operators throughout the world. Although resins have been utilized by some...

... Abstract Cementing is an integral part of well construction. Cement provides the seal, protection, and support for the casing to maintain the strong barriers that isolate the well. The benefits of cement are well known and a compendium of knowledge on well cement design and durability has been...

... Abstract Typical industry standard for evaluation of cement integrity at downhole conditions is through the use of acoustic measurements. These systems generate compressional acoustic waves which travel through wellbore fluid to impact the casing. Attenuation of these waves is used to derive...

... Abstract MPD enables drillers to navigate through narrow drilling windows to reach designed target depths. After a hole section is drilled, pressure management is still required to pull drill strings out and run and cement liners. Conventional cementing programs and procedures may...

... Abstract In this study, a field well was installed and cemented using the smart cement mixture with enhanced piezoresistive properties. The field well was designed, built, and used to demonstrate the concept of real time monitoring of the flow of drilling mud and smart cement and hardening...
