... of the water production, chemical isolation provides one effective solution to this issue. This paper describes a cost-effective coiled tubing (CT) intervention to implement permanent zonal isolation for water shutoff using an organically crosslinked polymer (OCP) sealant system and a modified organically...

... . Abstract Plug-and-perf multi-stage hydraulic fracturing completions in unconventional reservoirs rely upon complete hydraulic isolation from the previous stage to ensure effective treatment of the active stage. Failure to isolate stages can be a result of partially set plugs, plugs set in wellbore debris...

... Abstract This abstract is submitted as an addendum to SPE-188853-MS, which deliberate about Improving Sweep Efficiency by Zonal Isolation Using High Expansion Ratio Inflatable Plugs. "M" field contains medium gravity viscous crude (10-20cp) in high permeability sands. Application of EOR...

... Abstract Results from a long-term field study to improve zonal isolation show that rotating production casing in unconventional well laterals is possible and that it delivers excellent cement quality. This paper reports the results of the study. To date, 44 production strings have been rotated...

... Abstract Currently, hydraulic isolation of wells drilled with nonaqueous fluids (NAFs) relies heavily on the elimination of mud from the annuli before the placement of cement. Failure to expel all NAFs will result in residual fluid channels that will compromise well integrity and can even serve...

... Every cementing operation has a set of specific objectives combining technical consideration (ranging from simple fill-up criteria to sophisticated isolation requirements) with project economics and local regulations. To fulfill its objectives, the cementing design must first consider wellbore...

.... The comparison provided quantification of the actual in-situ contaminated cement condition. The cement shear properties offer an additional piece of information for drilling and cement engineers to evaluate cement sheath and validate well isolation objectives.This evaluation and validation become even more...

... some adopted from deepwater operations, has led to improved zonal isolation and operational efficiencies. The conventional methods used to cure losses during drilling with cement plugs can be inefficient usually requiring multiple attempts with mixed success. A revised method focuses on hydrostatics...

... of these materials in H 2 S environment. Objective Maintaining the integrity of the cement column throughout the life of the well is crucial in order to achieve full zonal isolation. In many cases, even following cementing best practices is not enough to prevent damage to the cement column. In the past, self...

... Abstract Openhole gravel pack (OHGP) completions are often selected as the preferred completion technique to provide long life, high capacity, low skin completions. One drawback to OHGPs, however, is the inability to isolate undesirable water or gas within the completion interval whether...

..., there was no solution to reliably stimulate a large un-cemented or openhole sections. This lead to potential losses of EUR in those wells where for some unplanned event, a section of the wellbore cannot be cemented or isolated with plugs. Recently, a well was drilled and unforeseen issues resulted in 3,300 feet...

... Abstract Utilization of chemical treatment to isolate or shut off zone is not uncommon in this industry. Cement will normally be chosen as candidate to perform the job as it is more permanent and more economically effective. With recent advanced technologies, cement particles are now designed...
