“…Results show that the formation of external filter cake on the core face has reduced the further invasion of the filtrate into the core. The return permeability value (74.0%) of the drilling fluid formulation containing nanocomposite was found to be higher than the PHPA system (67.0%) and it is a good value for water based drilling mud (Audibert et al, 1999). In case of PHPA system, the high filtrate invasion and spurt loss volume had lead to the more adsorption of the polymers on the core surface.…”

“…Its properties considered in the above equation correspond in fact to the filtrate properties since for WBM, filtrate viscosity has been evaluated to be close to water viscosity 7,9 . The potential damage due to polymers contained in the filtrate is globally represented by an hysteresis of filtrate/oil relative permeability curves for simulation of drilling and back flow periods.…”

“…The degree of alteration, generally called "Formation Damage", depends on a large number of parameters such as nature and characteristics of the drilling mud, formation properties and operating conditions. Formation damage can cause significant decreases in oil and gas productivity, especially for open hole completed horizontal wells [3][4][5][6][7][8][9][10] . Worldwide yearly lost production due to formation damage is equivalent to billions of dollars in lost revenue.…”

“…Since last decades, significant efforts have been made in laboratory to study permeability reduction due to nearwellbore formation damage [3][4][5][6][7][8][9][10] . In particular, IFP has developed specific laboratory testing equipment and procedures 9 to characterize drilling induced formation damage during overbalanced operations and to quantify the performance of various cleanup techniques used in the industry.…”

TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractIt is well known that formation damage due to drilling fluid has a huge impact on well productivities, especially for open hole completed horizontal wells. To evaluate this impact to keep maximum oil productivity, a numerical model has been developed to simulate formation invasion and damage during the drilling phase of a well. This model can be used to study the impact of various parameters related to drilling fluid properties or drilling conditions on well performances.In previous papers 1,2 , a methodology combining both experimental and numerical approaches has been proposed to model the near-wellbore formation damage for both waterbased mud (WBD) and oil-based mud (OBM) and filter cakes removal by natural clean up procedures. However, anisotropic permeability was not considered, although heterogeneities were taken into account. The main difficulty of near-well modelling of anisotropic media is that the generally recognised elliptic flow behaviour in the well vicinity is not valid as the well cannot be considered as a point (or line) source. Flow behaviour is radial at the wellbore boundary and becomes gradually elliptic when going away from the well. To accurately model near-wellbore formation damage, a new grid system, which is obtained based on elliptic coordinate transformation, is proposed in this paper, and a new numerical scheme is given for the modelling of near-well flow in anisotropic media.The proposed model can be used to study non-uniform formation damage and cleanup results around the well due both to permeability anisotropy and gravity effect. Examples are presented to study sensitivity of various parameters (fluid properties, drilling conditions, …) on well performances. This model is developed for the modelling of horizontal wells as well as slanted wells. It can be used as a tool for well design and construction. Finally, a field example in a deep offshore reservoir is presented to show an application of the developed model.

“…To quantify this impact both for overbalanced drilling (OBD) and underbalanced drilling (UBD), a near-wellbore numerical model has been elaborated (Ding et al 2002(Ding et al , 2004(Ding et al , 2006, that considers specific parameters deduced from special laboratory experiments according to the nature and characteristics of the drilling fluid (Alfenore et al 1999;Audibert et al 1999;Longeron et al 2000). In overbalanced drilling (OBD), formation damage is caused by the presence of filter cakes and invading drilling fluid in porous media.…”

It has been widely recognized that formation damage caused by drilling fluid has a huge impact on well productivities. The degree of formation damage can be studied using a numerical model. However, uncertainties in the prediction of productivity loss need to be investigated. To quantify these uncertainties, experimental designs combined with the Response Surface Methodology (RSM) are used to assess the impact of uncertain parameters on formation damage. This approach allows to identify the most influential parameters on well productivity loss and to estimate the risks of formation damage. A good control of the most sensitive parameters can limit productivity loss. This approach provides key recommendations for the selection of drilling fluid to maximize well performance.
