Paper presented at the SPE Formation Damage Control Symposium, February 14–15, 1996
Paper Number: SPE-31078-MS
... Abstract The evaluation of a present acid injection profile used in acid flowback analysis is an important tool for optimizing acid treatments, as it affects the acidizing process by improved results of hydrocarbon production rather than subjecting the well to yet another optimized acid...

Paper Number: SPE-0300-0030-JPT
Published: 01 March 2000
...Karen Bybee This article is a synopsis of paper SPE 58736, "Flowback Analysis of Acid Stimulation of Seawater-Injection Wells: Case Histories," by K.C. Taylor, SPE, and H.A. Nasr-El-Din, SPE, Saudi Aramco, originally presented at the 2000 SPE International Symposium on Formation Damage Control...

... of iron control additives, the volume of washout zones, the optimum flowback time, the relative amounts of carbonate minerals dissolved by the acid, and the dilution of the spent acid. Confirmation of well damage mechanisms was obtained by analysis of dissolved and suspended solids produced during each...

Paper Number: IPTC-21860-MS
... of all the ions in the water for each sample giving the concentrations over the flowback period. Abstract Acidizing is the most commonly used method to stimulate carbonate reservoirs. To achieve a better assessment of the operation, a flowback analysis is conducted. Flowback analysis can give...

Paper presented at the SPE International Conference on Oilfield Chemistry, April 8–9, 2019
Paper Number: SPE-193610-MS
... Abstract The success of carbonate acidizing depends on the selection of proper fluid recipes, reservoir formation parameters, job design, and execution. Analysis of flowback spent acid will improve the acidizing process in future treatments, enhance the designed recipes and treatment design...

Paper presented at the IADC/SPE Asia Pacific Drilling Technology Conference and Exhibition, August 27–29, 2018
Paper Number: SPE-191017-MS
... Abstract Acidizing treatments are the primary technique to enhance production of carbonate formations. Analysis of historical matrix treatment flowback, and laboratory assessment provide insights on the reservoir response to the acid recipe, and thus, positively enhance the selection of fluid...
