... in order to study the effect of adding the epoxy resin into the geopolymer slurry in terms of the final cement's setting time and compressive strength, Table 1 . In addition, testing conditions are set to simulate downhole conditions. Our aim is to increase the final cement strength while having...

... energy concept. The methodology is used to compare different wells with and without mud loss conditions using real-time data from two wells. Mechanical specific energy and hydraulic mechanical specific energy (HMSE) using the pressure component were calculated. The unconfined compressive strength...

... such as fiber-reinforced polymer composites dated back to 1940-50s to replace metals such as aluminum, titanium, and steel for higher stiffness, strength-to-weight ratio, and "corrosion-free" properties ( Roeseler W.G., Sarh B. and Kismarton M.U., 2007 ). Oil and gas industry also attempted using composite...

...-structure development (during early stages of deposition-transition time during ductile and cementation periods) Fig. 3 A, B and C are the plots of the mechanical properties from table 1, and it shows the variations in unconfined compressive strength (UCS), static Young's modulus ( E sta...

... To achieve its goal, the material must have outstanding flow properties to penetrate potential cracks in the cement plug. It must also display a high bond strength to both the cement, the casing and the rock formation. The sealant properties are presented in this study and compared with microfine...

...) HCl for comparison. Lactic and formic acid concentrations were set to be (0.5 or 1 M), and HCl concentration was calculated as appropriate to reach a blend with strength of 4.4 M. In terms of corrosivity evaluation, blends of lactic and HCl acids showed a corrosion rate of up to 1.97 lb/ft 2 at 300...

... while drilling but with limited success. A new lost circulation solution combines lightweight (10.5- lbm/galUS) high solids fraction cement (trimodal system) and a thixotropic agent, which develop fast gels with high compressive strength. Thus, it enables plugging of large voids and fractures to deliver...

... Abstract The rock properties in the reservoir rocks represent stiffness and strength properties, while the unexpected variation in the dense intervals varies with the fabric and other sedimentological and rock types. The purpose of this paper is to present the mechanical rock testing parameters...

... Resin-cement composite systems provide benefits of both the resin and the cement material properties. Both pure resin and composite designs can be customized based on the operator’s challenge, with respect to density, viscosity, rheology, fluid loss, static gel strength, thickening time...
