Plantain Peels Powder, Burnt Palm Head Powder and Commercial Sodium Hydroxide as Additives for Water Based Drilling Mud

Abstract

Drilling operation efficiency is enhanced by the application of drilling mud constituted with suitable additives. This work investigates the use of locally sourced plantain peels powder (PPP) and burnt palm head sponge powder (BPHSP) in comparison with the use of commercial sodium hydroxide (NaOH) as additives for the enhancement of the pH and rheological properties of water-based mud. The water-based mud samples with and without various amounts (1.0-5.0 g) of PPP, BPHSP and commercial NaOH, respectively. Analyses of the results revealed that the pH and rheological properties (apparent viscosity, plastic viscosity and yield point) of the formulated waterbased mud were relatively enhanced with the respective use of the commercial NaOH, BPHSP and PPP as additives. The pH, apparent viscosity and yield point respectively increased with increase in the quantity of each of the added additives (commercial NaOH, BPHSP and PPP). The commercial NaOH had the highest percentage of improvement on the mud pH with 22.2-50%, followed by that of BPHSP (16.7-44.4%) and PPP (11.1-33.3%), respectively. Therefore, commercial sodium hydroxide, burnt palm head sponge ash powder and plantain peels powder can respectively be used as additives to enhance or improve the pH and rheological properties (viscosity and yield point) of water-based mud.

Evaluation of pH of Drilling Fluid Produced from Local Clay and Additives

“…Also an increased in pH for plantain powder (9 to 11.75) and banana powder (up to 11.42) additives was reported. Peretomode (2018) reported increased in pH of drilling mud from 9 to 11-135 for commercial NaOH, then from pH 9 to 10-12 for plantain peels powder, while the burnt palm head sponge powder achieved increased in pH from 9 to 10.5-13. In addition, plastic viscosity and apparent viscosity of 4-6cP and 6.5-12.5cP for NaOH, 5cP and 6.5-11cP for locally sourced additives was reported.…”

“…Importantly, the pH of drilling mud is one of the key parameters to determine its performance. As such, it performs better within pH range of 8.0 to 10.5 for water base mud (Peretomode, 2018). Drilling mud lower than pH 7 suggests it being acidic, which leads to pitting, corrosive to materials and equipment, and simultaneously result in environmental pollution (Okorie, 2009).Therefore, maintaining the pH of the drilling fluid within defined standard range is important during drilling operations.…”
