Paper presented at the SPE International Conference and Exhibition on Formation Damage Control, February 19–21, 2020
Paper Number: SPE-199269-MS
... Abstract Using flowback additives in slickwater fracturing fluids is a relatively recent innovation, and regained permeability testing using corefloods is the preferred performance evaluation method. The coreflood rig simulates the hydraulic fracturing process by injecting the fracturing fluid...

Paper presented at the SPE International Conference and Exhibition on Formation Damage Control, February 19–21, 2020
Paper Number: SPE-199293-MS
... Abstract The presence of residual oil or gas during fines migration in porous media greatly affects particle mobilization and capture. This paper investigates the effects of kaolinite content on fines migration and formation damage in the presence of oil residual. We carried out corefloods on...

Paper presented at the SPE International Symposium and Exhibition on Formation Damage Control, February 13–15, 2008
Paper Number: SPE-112500-MS
... derived analytical-model-based method for determination of both coefficients from breakthrough concentration and pressure drop during laboratory coreflood on quasi steady state commingled flow of injected and formation waters, and also from just pressure drop measurements during two corefloods with two...

Paper presented at the SPE International Symposium and Exhibition on Formation Damage Control, February 18–20, 2004
Paper Number: SPE-86477-MS
... importance of using the correct coreflood protocol when evaluating an oil soluble scale squeeze inhibitor. Examples of different procedures for different types of scale inhibitor show that use of the incorrect procedure can seriously influence the formation damage and lead to misapplication in the field...

Paper Number: SPE-39420-MS
... order to optimize treatment volume and minimize precipitation of hydrated silica and other precipitates. To validate the model a series of laboratory coreflood tests has been fully analyzed. The results indicate that the formation of silica gel is significant based on the HF effluent analysis. The same...

Paper presented at the SPE Formation Damage Control Conference, February 18–19, 1998
Paper Number: SPE-39595-MS
.... Before pumping any type of remedial stimulation treatment, it was decided to test the recommended acid formulation in the lab. Acid corefloods were performed on composite samples from whole core using a typical 10% HCl/l .5% HF formulation. This acid formulation proved to be damaging as lab results...

.... Write Librarian, SPE, P.O. Box 833836, Richardson, TX 75083-3836. U.S.A., fax 01-214-952-9435. Abstract Solids characterisation forms an integral part of many studies related to petroleum engineering, e.g., coreflood evaluation as- sessment of fines migration and characterisation of precipitates; and is...

Paper presented at the SPE Formation Damage Control Symposium, February 26–27, 1992
Paper Number: SPE-23785-MS
... consolidated rocks using conventional coreflooding apparatus have been studied in conjunction with LMP measurements. LMP measurements were conducted before and after the formation damage experiments. The present paper includes an interpretation of a complex formation damage mechanism involving precipitation of...
