... in the oil and gas industry. The research involved creating cement slurries by mixing Saudi Class G cement with red mud in an 85/15 ratio. The primary objective was to assess whether red mud could be used as a sustainable alternative raw material in cement production without compromising quality. To achieve...

... the CT to penetrate and reduce injectivity of the watered-out zone 1.1 m 3 of cement slurry was placed through the CT in the annulus liner/OH via additional perforations made by a HPJT The top of cement was tagged and successfully pressure tested up to 1,300 psi. The new layer was opened...

... formation Considering the challenges, multiple solutions were engineered from the initial design of cement slurries to the completion of the cement job. To combat lost circulation, a thixotropic and acid-soluble cement was tailored to remedy losses and prevent accidental sidetracking. The fluid...

...Materials and Methodology The cement slurries used in this study were prepared according to API standards API (1991 , 2013 ) and using Saudi Class G cement, an antifoaming agent, a fluid loss additive, and tap water with a salinity below 300 ppm. All materials, including the cement...

... for the cementing job. The selection of cement slurry and cementing placement technique is crucial in successful cementing jobs with minimal loss. Abstract Lost circulation while cementing intermediate sections across the Umm er Radhuma (UER) Formation, a naturally fractured limestone formation in UAE...

... Fraction (SVF) exceeding 56% and a high-density cement mix of 12.5 ppg. This modification aimed to increase the visibility of the cement system in the evaluation logs, thus enhancing the accuracy of Cement Bond Log (CBL) readings. The high-density cement slurry system was designed to achieve higher...

... and expandable slurry design was proposed to overcome wellbore stresses. Third, a novel laboratory testing procedure was developed to confirm the shear bonding of the cement slurry to the halite salt formation. In the event that the 8.5-in. openhole section across the salt formation encounters high-pressure...

... protected. Cathodic protection addresses the exposure of the casings to the external corrosive environment but doesn’t help in the double casing ("shielded") area. Due to the fact that complete fluid displacement with absolutely clean cement slurry behind the casing cannot be guaranteed and there is always...

... of sacrificial fiberglass pipe to be able to pump a higher volume of cement slurry with flash setting silicate spacer that improves the possibility of curing losses and mitigating stuck pipe risk. In addition, it shows how smearing the wellbore with gravel can enhance the chances to cure the most challenging...

... full-scale application in the petroleum industry is yet to be realized. One critical area where geopolymer cement can play a significant role is in high-pressure well cementing applications. To replace heavy-weight Portland cement slurries in these applications, the development of high-density...

.... Cement integrity in oil and gas wells is crucial to ensure excellent zonal isolation and prevent gas migration to the surface over a long production time. Therefore, cement slurry should be carefully designed to yield better performance in sealing the annulus between the casing and drilled formations...

... Simsima has caused the hole to collapse on the BHA resulting in multiple sidetracks till the well inclination was dropped to manage completing the section. Attempts to cure the losses in the UER to date have been unsuccessful. Conventional extended cement slurries have been widely used to cure losses...
