... performed on the new CS-LCM included evaluating its flowability before and after the reaction and estimating the compressive strength. Additionally, the developed strength robustness of the CS-LCM was evaluated by its ability to withstand large differential pressures across extra-large holes (31 mm) in test...

... the compressive strength of class G cement by 17.8%. Polypropylene fiber can be used as an alternative material for silica floor in shallow wells. Polypropylene fiber has a significant effect on reducing the porosity and the permeability of the base cement. Cement Slurry Preparation Polypropylene fiber...

... in which one reflected the bit exponent and the other reflects the formation compressive strength. Each formation type had its own compressive strength coefficient. Khoukhi in 2012 compared extreme learning machines (ELM) and radial basis function networks (RBF) on Bourgoyne and Young's model...

... of the consolidated sand pack increases with increasing PEA concentration without sacrificing much compressive strength. This will help reducing the amount of resin used and therefore reducing the overall chemical cost. Fig. 2 shows the sand packs consolidated by the chemical with various concentration of PEA...

... Abstract Unconfined compressive strength (UCS) of rock is a key parameter in drilling and stimulation of oil and gas wells such as wellbore stability and fracturing operations. Better estimates of UCS could increase the efficiency of drilling and stimulation operations. Current techniques...

..., complete circulation can be achieved deploying this slurry. The set cement mechanical properties, including compressive strength, have significantly improved which is essential for ensuring long-term isolation. Conventional water-extended cement slurries are not considered adequate to isolate...

... challenge faced initially was with tractoring in the low uniaxial compressive strength (UCS) of the reservoir formations (UCS=1400-3000 PSI) in Bahrain. Since tractoring is known to be an effective deployment method for hard formations (UCS>5000 PSI), the new OH tractoring technology (UltraTRAC...

Thickening time of 2–10 hours can be adjusted by changing retarder concentrations. (2) Less than 35 ml API fluid loss and thin and hard filter...

... Abstract Cementing deep high pressure and high temperature (HPHT) gas wells has always been a challenge. Conventional heavy weight cement systems which have been used in the past have often had to sacrifice the set cement mechanical properties such as compressive strength, permeability...

The study results showed that all the independent variables play important roles in achieving an appreciable increase in compressive strength of the new system in comparison with other additives. Also, the new system out-performed the other additives as it shows no reduction in conductivity...
