... at country level. In our current challenging drilling environment, a competent annular zonal isolation is required for long-term integrity. The well known worldwide cement practices has been key to obtain good results, among them, casing rotation has been widely applied to liners but not so commonly to full...

... Abstract In the Talara basin, the cementing of the production section represents a challenge to achieve effective zonal isolation around the pay zone and ensure an efficient hydrocarbon production. For this purpose, well cement design must be tailored to accomplish specific goals. Challenges...

.... It evaluates Primary cement Using bond logs that was run three days after the cementing operation. The logging results indicate an average amplitude of around 5 mV, so the 5 ½" in. Casing cement job had 90% average bond index. Good zonal isolation was achieved. In addition, Mechanical factors...

... Abstract The objective of this paper is to present the improvement in zonal isolation and cement sheath properties using foam cement in heavy oil Chichimene Field in Colombia. Achieving complete zonal isolation in the pay zone have become a major challenge in these fields, recently, given...

... purpose of the primary cement job is to provide zonal isolation for the life of the well. To achieve good initial annular isolation and allow the formation to be produced reliably, it is necessary to effectively displace all the drilling fluid from the well. This can be achieved by using a combination...

... concerns in an effort to effectively obtain long term zonal isolation. Application of cementation engineering for production casing in development fields has resulted in the need for low-density slurries that can rapidly develop compressive strength. Furthermore, improvement in rock mechanics...

... conditions and low fracture pressures. In these wells, combinations of demanding well and formation parameters have made it more difficult to achieve successful cement placement. Minimizing losses during cement placement, achieving predicted top of cement (TOC) and reliable zonal isolation are current...
