“…Rice husk, for instance, has been studied by Soares et al (2015) and Rita et al (2018) as an additive to improve the mechanical properties of oil well cement matrices. Another study by Novriansyah et al (2016) investigated the effect of activated charcoal obtained from palm kernel shells on the strength development of a cement-nanosilica-charcoal mix. The study found that the addition of activated charcoal significantly increased the compressive strength of the cement mix, with the optimum percentage of charcoal being 5 % by weight of cement.…”

Cementing is one of the most critical drilling operations in the oil and gas industry. However, the production and utilization of cement is a major emitter of CO2 into the atmosphere. Processes and technologies that can reduce the overall carbon footprint of the oil and gas industry while meeting the increasing global demand for energy are of key interest to stakeholders. Furthermore, local cement when compared with imported class G cement is unable to meet the compressive strength requirement of an oil well cement. Therefore, the objective of the present study is to investigate for the first time the capability of natural pozzolana clay from Ghana as a sustainable alternative to improve the physical and rheological properties of local Portland cement for well cementing operations. Pozzolana is a naturally occurring clay that is mainly composed of silica and alumina. To achieve this, well cementing blends of varying percentages with up to 30 % of pozzolana and 70 % of local Portland cement by mass were formulated and examined to determine their rheological properties, free fluid, and compressive strength. The experimental results indicated that blending natural pozzolana material and local Portland cement effectively reduced the free fluid of local Portland by up to 85 % and the plastic viscosity by up to 62.5 %. Furthermore, the addition of pozzolana significantly increased the compressive strength of local Portland cement by up to 188.5 %. Based on the results, it can be concluded that pozzolana can improve the performance of local Portland oil well cement and further reduce the carbon footprint of the oil and gas extraction process by minimizing the quantity of Portland cement used for well cementing operation.

“…If CSC is exposed to heat and the temperature increase up to 100 o C, the water molecule will vaporize and CSC turns out as fluid (liquid or gas) absorber. Experiment by Hawley [7] indicated that charcoal purification and tar creation occur and continue when the temperature reaches 500 o C. Less experimental studies have been investigated the effect of heating temperature to CS and SBS parameter. Work by Novriansyah [8] has approved that CSC additive can enhance cement strength.…”

Abstract. This experimental study introduces an organic wasted material, which hopefully can be another solution besides other expensive chemical-based additives. The study intends to investigate the effect heating temperature on charcoal powder, which is originated from the coconut-shell waste material, related to its ability in enhancing cement strength. Six samples with different additive concentration should be prepared before initiating the strength test. the strength test principally follows the bi-axial loading test procedure, where each sample will be burdened by a certain amount of the load force until failure condition was reached. The recorded pressure where the failure occurs will be treated as maximum load, which is needed for determining compressive strength and shear-bond-strength values. Those parameters should be in refer to respectable standard in the oil and gas industry. Results from the strength test clearly indicate that higher heating temperature yields to a cement with a high strength. The optimal heating temperature has reached for a sample with 700 o C charcoal powder. It is a potential opportunity in increasing the economic value of the waste material.
