“…Fluid loss control in solids-free brines is generally achieved by; increasing the viscosity of the fluid [5][6][7][8][9][10][11][12][13][14][15][16] and developing internal/external filter cake using lost control additives 17 . In a recent study, Svendsen et al 18 has shown that extensional viscosity can be successfully used to establish an internal filter cake in association with a coiled tubing drilling fluid application.…”

Xanthan Gum has been used extensively as a viscosifier in the oil industry for different applications due to its unique rheological properties. An experimental study has been conducted to investigate the formation damage characteristics of Xanthan Gum based fluids and the results are presented in this paper.A series of core flow experiments have been conducted to investigate the possible relationship among the Xanthan Gum concentration, fluid extensional viscosity, shear viscosity, filtration loss characteristics, pressure drop across the core samples and hence, any change in the original permeability of the porous media.Results of extensional and shear viscosity measurements, API filtration loss tests, and formation damage tests conducted by using fluids of different xanthan gum concentrations are shown in this paper.

“…The excess pressure drop may be due to the substantial extensional component present in this flow configuration (Khan et al, 2003;Durst et al, 1987;Jones and Walters, 1989;Saasen et al, 1990;Navarrete et al, 2000). Naverrete and Mitchell (1995) suggested that for the XG solutions, the flow was dominated by the shear viscosity, whereas for the PHPA solutions the flow was dominated by the extensional viscosity.…”

In this study, the effect of the rheology of viscoelastic fluids on the formation of internal filter cakes has been investigated. A series of core flow experiments have been conducted to investigate the possible relationship among the polymer concentration, fluid extensional viscosity, shear viscosity, filtration loss characteristics, and pressure drop across the core samples, and hence, any change in the original rock permeability. Results of extensional and shear viscosity measurements, API filtration loss tests, and formation damage tests conducted by using three different partially hydrolyzed polyacrylamide (PHPA) solutions (0.5, 1.5, and 3.0 lb/bbl) are shown. Comparison of the PHPA test results with the previously published xanthan gum (XG) test results is also provided.

“…It has been recognized that the excess pressure drop may be due to the substantial extensional component present in this flow configuration. [5][6][7][8][9][10][11][12][13][14] Durst et al 8 , for example, suggested that as much as 75 % of the pressure losses in the formation may result from extensional viscosity.…”

TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractFormation of internal cake due to the invasion of reservoir rock by drilling, completion, and fracturing fluids is known to be one of the major causes of productivity reduction. Although the causes of internal cake formation are relatively well identified, the actual physical mechanisms involved in internal cake formation are yet to be understood. In particular, a quantitative means of relating physical properties of fluids to the degree of productivity reduction are not well established. A detailed investigation on the role of the rheology of viscoelastic fluids on the formation of "internal filter cakes" is, therefore, needed.The extensional viscosity for pure liquids without any structure is 3 times the shear viscosity. For these liquids, contribution of the extensional viscosity to the pressure loss is, therefore, constant and often neglected. However, for viscoelastic fluids, such as polymer based drilling and completion fluids, the extensional viscosity may be several orders of magnitude larger than the shear viscosity. This will lead to a significant increase in pressure loss, which is very often attributed to the development of internal cake.A series of core flow experiments have been conducted to investigate the possible relationship among the polymer concentration, fluid extensional viscosity, shear viscosity, filtration loss characteristics, and pressure drop across the core samples and hence, any change in the original rock permeability.Results of extensional and shear viscosity measurements, API filtration loss tests, and formation damage tests conducted by using two different Partially Hydrolized Polyacrylamide (PHPA) solutions ( 1.5 and 3.0 lb/bbl) are shown in this paper.Comparison of the PHPA test results with the previously published Xanthan Gum (XG) test results are also provided.
