Primary Investigation of Barite-Weighted Water

The removal of barite filter cake is a challenging problem because the conventional filter cake removal treatments that use hydrochloric acid (HCl) or chelating agents were ineffective in dissolving Barite sagging can be prevented or mitigated using several approaches. Mohamed et al. [33] have evaluated the effect of reducing the particle size of barite and concluded that using micro-sized barite reduced the sag factor, but it did not eliminate barite sagging; i.e., sag factor was greater than 0.53.Mitigation of barite sagging during the drilling of high-pressure

Single stage filter cake removal of barite weighted water

Based on the result of this work the filter cake removing formulation dissolved more than 90% of the filter cake formed by real barite drilling fluid in a single stage within 24 h. The removal formulation consists of high pH potassium base DTPA of 20 wt% concentration, enzyme as a polymer degrading agent, and one of the following convertingpressure especially for deep gas and oil wells.14 The mud ﬁlter cake will form due to the pressure gradient and with the possibility of invasion into the formation.15 This could cause the barite to precipitate as a scale in the near-wellbore area, which decreases the productivity and can cause erosion to theMinimizing the Barite Scale in Carbonate Formations

Experimental approach for assessing filter-cake removability

Predicting formation damage in cased-hole and open-hole completion wells is of high importance. This is especially relevant when the damage is caused by reservoir drill-in fluids hence being well-bore induced. Cake filter removal has proven to be a good approach to estimate induced damage and to evaluate drill-in fluids’ performance. We Elkatatny, S.M.

Barite sag is a challenging phenomenon encountered in deep drilling with barite-weighted fluids and associated with fluid stability. It can take place in vertical and directional wells, whether in dynamic or static conditions. In this study, an anti-sagging urea-based additive was evaluated to enhance fluid stability and prevent solids sag in water Secondary damage is a form of formation damage that occurs during the removal process of barite filter cake layer but has received less attention. Regained permeability testing using High Pressure High Temperature (HPHT) Filter Press aimed to test the ability of several commercial filter cake breakers in removing synthetic-based Evaluation of secondary formation damage caused by the

A common weighting material used in the oil and gas industry is barite. In this work, the impact of barite concentration on water-based drilling fluid was evaluated. The investigated drillingThe flowback test conducted showed a positive outcome where 82.7% return was obtained when soaked into the filter cake breaker for 72 h. Pressure at which filter cake is removed and easy backflow from formation to the wellbore is allowed is known as lift-off pressure [23].

Effective removal of iodate by coprecipitation with barite:

Iodate was removed from aqueous solution by coprecipitation with barite even in the presence of competitive anions. Iodate was substituted for SO 42− site in the barite structure. Charge compensation was achieved by the substitution of sodium Na + -IO 3− pairs at the nearest Ba 2+ site.Summary. Barite is one of the most common weighting materials used in drilling fluids for deep oil and gas wells. Consequently, the main source of solids forming the filter cake is “barite particles,” the weighting material used in drilling fluids. Barite is insoluble in water and acids such as hydrochloric acid (HCl) and formic, citric, and acetic acids, Removal of Barite-Scale and Barite-Weighted Water- or Oil

Barite (BaSO4) and celestite (SrSO4) are the end-members of a nearly ideal solid solution. Most of the exploitable deposits of celestite occur associated with evaporitic sediments which consist of gypsum (CaSO42H2O) or anhydrite (CaSO4). Barite, despite having a broader geological distribution is rarely present in these deposits. In this
