Paper presented at the ADIPEC, November 4–7, 2024
Paper Number: SPE-222228-MS
... Abstract The introduction of Perforate, Wash and Cement (PWC) techniques have delivered a step-change in annular cement remediation efficiency versus conventional methods. The development of Tubing-Conveyed Perforating (TCP) charges capable of perforating production casings without damaging...

Paper presented at the ADIPEC, November 4–7, 2024
Paper Number: SPE-222823-MS
... enhanced safety and permanence in the same reservoirs that have securely held oil and gas for millions of years. This paper explores the benefits of deploying novel cementing technology in CCS wells in Eastern Australia. CO 2 injection leads to a corrosive environment, which can cause cement sheath...

Paper presented at the ADIPEC, November 4–7, 2024
Paper Number: SPE-222504-MS
.... This necessitated further planning, such as adjusting the length of the liner and performing off-bottom cementing. All whilst ensuring the lower completion, featuring inflow control devices (ICDs), could be run unhindered. TAML level 4 junctions require precise planning, orientation, and access. The integrity...

Paper presented at the ADIPEC, November 4–7, 2024
Paper Number: SPE-223032-MS
... Fig. 5a shows the ultrasonic sensor placement on a rotating sub and the propagation of the signals. Two sets of ultrasonic transducers are placed opposite to each other (180°). The side with the single transducer provides the traditional ultrasonic measurement, which provides cement acoustic...

... and remarkable successes. Over 70 wells have been meticulously drilled and brought into production. Upon completion, the operator faces the critical task of ensuring well integrity, which hinges on the cement's performance against each section of the casing under scrutiny. There are two types of well designs...

Paper presented at the ADIPEC, November 4–7, 2024
Paper Number: SPE-222408-MS
... For repairing cement to cure SAP in B annulus, there are different options, for cement that is highly bonded to the casing but exhibit micro-annulus with cross flows, technologies around steel removal as standard section milling or dual/triple casing section milling are to remove casing...

Paper presented at the ADIPEC, November 4–7, 2024
Paper Number: SPE-222750-MS
... In this context, if feasible, casing removal should be limited to that required to establish a sound environmental barrier. Casings within the zone where the primary and secondary barriers are to be located could be left in place if they are structurally sound, and perforation, wash, and cement (PWC) methods...

Paper presented at the ADIPEC, October 2–5, 2023
Paper Number: SPE-216898-MS
... Abstract Successful placement and curing of cement behind casing is critical for the environment, operational safety, economics and lifespan of any oil and gas well. Cement bond logging technologies have evolved, from basic CBL, to include different measurement physics, sensor technologies...

Paper presented at the ADIPEC, October 2–5, 2023
Paper Number: SPE-216885-MS
... During venues related to cement quality, shareholders, stakeholders, and suppliers shared and presented findings, lessons learned and best practices to improve zonal isolation. The outcomes of studies, workshops and committees could be divided into the following three categories: Abstract...

Paper presented at the ADIPEC, October 2–5, 2023
Paper Number: SPE-216375-MS
... Circulating Density (ECD), wellbore stability, hole cleaning and stuck pipe. Technological changes were implemented, including the utilization of newly developed spacers and cement slurries to achieve competent cement behind 9-5/8" casing for reservoir sealing, the use of circulating subs across open...

Paper Number: SPE-217005-MS
... and the line top inflow testing are time consuming, especially in challenging well environments. The paper documents executed two case studies that illustrate how a Systematic Risk Control Approach enables the execution of drilling out cement, negative Test, Wellbore clean out, and Casing Pickling...
