“…Al., 2019;Okon and Agwu, 2015), provided it's carrying capacity and other essential properties are not compromised. The PV values of the three mud samples fall within the API accepted range for plastic viscosity of 8 -35 cP except the PV values of 5 cP at 100 o F and 6 cP at 140 o F of the BL mud sample (Orji et al, 2018;Biwott et. al., 2019).…”

“…It is a measure of the shear stress required to initiate flow after a static period or a period of inactivity (Onojake and Chikwe, 2019). A higher gel strength value is required to prevent mud sagging and fluid loss, and also to maintain wellbore stability when drilling operations are paused provided it falls within the API range of 2 -35 lb/100ft 2 for 10 minutes gel strength (Biwott et al, 2019;Khan et al, 2023). The variation of the 10-Minutes and 10 -seconds gel strength with temperature is also presented in Figure 3.…”

Drilling muds have relied on a range of base fluids, with mineral oil-based formulations dominating the landscape for decades. However, mineral oil-based muds contain a plethora of toxic aromatic compounds which are persistent in the environment. Hence, the objective of the paper was to synthesize and compare the performance properties of drilling muds formulated with C14 and C16 esters of lauric acid using appropriate standard procedures. Benchmarking of the esters with a reference synthetic base fluid indicated that the esters have suitable physicochemical properties for application as synthetic base drilling fluid. Their kinematic viscosities are within the API recommended range, ethyl laurate (EL) has a lower cloud point relative to the reference, and the two base fluids have higher flash point and electrical stabilities relative to the reference. The results obtained from comparing the rheology of muds prepared with ester products and that prepared with the reference fluid indicate that the muds prepared with ethyl, and n-butyl laurate have higher electrical stability than the mud prepared with the reference base fluid. The results also show that the muds prepared with the esters synthesized in this work displayed better rheology profiles than the mud prepared with the reference synthetic base fluid. However, ethyl laurate (EL) formulated mud had better thermal stability than n-butyl laurate (BL) at the temperature range studied. Through the investigation of these ester-based drilling muds, we showcased the potential of these esters to enhance drilling efficiency, minimize environmental impact, and optimize operational performance.

“…In one recent study Moringa oleifera extracts have been used to improve the rheological properties of the water-based drilling fluids. [169] The extraction of Moringa oleifera cationic protein (MOCP) could help in developing an environment friendly shale inhibitor. It is already known that the nanosilica improves the shale inhibition characteristics of shale formations.…”

Nanomaterials find several applications in the oilfield operations. In oilwell drilling, nanomaterials are being used for mitigating wellbore instability conditions, improving thermal stability of the fluid, minimizing formation damage by preventing fluid invasion into the reservoir, improving fluid rheology, and controlling fluid loss. A wide range of nanomaterials from organic as well as inorganic and composites are being developed to accomplish the mentioned functions. Significant nanomaterials being developed include nanocellulosic particles, nanoclay, nanosilica, nanometals, nanometal oxides and nanopolymers. Improving fluid properties to develop smart fluids by the incorporation of nanomaterials is an emerging research field which is yielding promising results. This review article presents the recent development made in the applications of the nanomaterials in drilling fluids especially the nanosilica particles surface modified by organic ligands. Surface modification of nanosilica with organic ligands namely 3‐Glycidoxypropyl‐triethoxy silane (GPTS), hyperbranched polyethyleneimine (HPEI) and Moringa oleifera cationic protein (MOCP) are discussed. Applications of nanomaterials in drilling fluids to minimize wellbore instability, prevent formation damage, improve thermal stability and conductivity, stabilize fluid rheology, improve hole cleaning, and minimize the chances of downhole string sticking have been reviewed.

Aim: Polymer flooding is used for enhanced oil recovery. Only polymers that can withstand harsh environments work best. HPAM is mostly the polymer used for enhanced oil recovery because it is available and cheap, but it does not withstand high temperatures and high salinity reservoirs. Xanthan Gum withstands high temperatures and high salinity reservoirs, but it is expensive and plugs the reservoir. The aim of this study is to compare the salinity stability of gum Arabic and Terminalia Mantaly, a novel biopolymer, with commercial Xanthan gum. Study Design: Locally formulated biopolymers from gum Arabic exudates bought from Bauchi State in Nigeria and from Terminalia Mantaly exudates obtained from the University of Port Harcourt. The appropriate rheological tests were carried out at the laboratory. Place and Duration of Study: The laboratory experiments were carried out at the department of Petroleum Engineering, Covenant University, Ota in Ogun State of Nigeria between 2020 and 2021. Methodology: The gum Arabic, Terminalia Mantaly and Xanthan Gum powders were dissolved in deionized water to get various concentrations in ppm. The polymers were mixed and kept for 24 hours to achieve a homogenous solution. The Automated OFITE® Viscometer at different revolutions per minute (RPM) of 3 (Gel), 6, 30, 60, 100, 200, 300, and 600 was used to measure the rheological properties of the various concentrations before Sodium Chloride (NaCl) and Calcium Chloride (CaCl2) of various concentrations were added and allowed to hydrate for another 24 hours before measuring their rheological properties again. Results: The study showed that Xanthan Gum, Gum Arabic, and Terminalia Mantaly biopolymers can be used in high salinity reservoirs. Terminalia Mantaly, a novel biopolymer, is insensitive to salinity in monovalent and divalent ions. Conclusion: Xanthan gum exhibited high viscosity even at low concentrations. Gum Arabic exhibited good tolerance to salinity at NaCl 3.5%. Terminalia Mantaly was very stable with both monovalent and divalent ions. Divalent ions have more effects on polymers than monovalent ions in reservoirs. Recommendation: It is recommended that Terminalia Mantaly be investigated more, as it can replace imported biopolymers for Enhanced Oil Recovery (EOR).
