Drilling fluid with better rheological and filtration properties control are required to optimise the performance of oil well drilling. In this study, a non-ionic anionic surfactant was used as an additive in water-based drilling optimize their properties. The rheology taken after being hot rolled for 16 hours at 250oF 275oF, while tests were conducted temperatures up 300oF. It found that improved Moreover, additives 41.3% more effective reducing loss compared mud without surfactants. long...
Nanomaterials are good potential additives in drilling fluid to improve the thermal and physical-mechanical properties of fluids, but their use this field is still scarce. Ester-based (EBDF) an environmentally friendly fluid. However, its restricted low moderate temperatures due poor hydrolytic stability. This study investigates roles morphology graphitization carbon nanomaterials on rheology, filtration, emulsion stability EBDF at high pressure temperature (HPHT) conditions. Various were...
The abundant oil palm empty fruit bunch (OPEFB) as by-product of milling processes exhibits a potential an alternative cellulose feedstock for bio-adsorbent. This study aimed to produce highly carboxylated bio-adsorbent direct industrial application from OPEFB-based via mercerization and followed by esterification with succinic anhydride (SA) enhance its adsorptive capability towards hazardous heavy metal dyes ions. modification using SA provides the carbon backbone platform carboxyl group...
This study evaluated the potential use of three polyol esters (POEs) derived from palm oil as a lubricant in bentonite suspension drilling fluid.Three different POEs were investigated, which are pentaerythritol ester (PEE), trimethylolpropane (TMPE), and neopentylglycol (NPGE).It was revealed that reduced coefficient friction (COF) by more than 80%.However, TMPE NPGE undesirably caused foaming altered gel texture suspension.PEE showed best performance it produced highest lubricity lowest...
