Oil-based mud has shown a commended performance over the years in mitigating borehole instability especially when penetrating through a reactive shale zone which is known to have swelling and dispersion problems. However, the strict environmental regulations worldwide have limited the use of oil-based mud. Therefore the methyl glucoside, known as MEG, a specially formulated water-based mud has been introduced where its performance is close to the oil-based mud. This project studied the effect of using MEG in potassium chloride (MEG/KCl) mud in controlling shale swelling and dispersion. Five different concentrations (0, 5, 15, 25, and 35% by weight) were used in the hot rolling dispersion test. Besides, the rheological properties and fluid loss control were also tested as per the American Petroleum Institute – Recommended Practice – 13B (2009). The results showed that MEG/KCl mud was capable of improving the shale inhibitive performance to mitigate the shale swelling and dispersion problems. The higher concentration of MEG used such as 25% and 35%, the less shale would swell or disperse. However, the effectiveness of MEG was corresponding with clay content present in the shale.

Lumpur metil glukosida, atau dikenali sebagai MEG, ialah lumpur dasar air terkini yang mesra alam. Lumpur ini mempunyai prestasi yang hampir menyamai lumpur dasar minyak. Projek ini dilaksanakan bagi mengkaji kesan penambahan MEG ke dalam lumpur natrium klorida (MEG/NaCl) untuk mengawal pengembangan dan penyerakan syal pada beberapa kepekatan yang berlainan, iaitu 5% hingga 35% berdasarkan berat. Kajian ini melibatkan ujian penyerakan putaran panas yang berdasarkan American Petroleum Institute – Recommended Practice – 13I. Sifat pengawalan sedemikian turut dikaji menggunakan beberapa sampel syal yang mempunyai kereaktifan dan kandungan lempung yang berlainan. Selain itu, prestasi lumpur MEG/NaCl turut dikaji menerusi ujian sifat reologi, kawalan kehilangan turasan, aktiviti air dalam lumpur, dan proses penuaan, sebagaimana yang dicadangkan dalam American Petroleum Institute – Recommended Practice – 13B. Kajian menunjukkan bahawa lumpur MEG/NaCl boleh mengurangkan masalah pengembangan dan penyerakan syal. Namun begitu, kepekatan yang berkesan adalah bergantung kepada kereaktifan dan kandungan lempung yang wujud dalam sampel syal. Hasil kajian juga menunjukkan bahawa MEG ialah agen kawalan kehilangan bendalir yang baik. Kata kunci: Ujian penyerakan putarasan panas; metil glukosida (MEG); penyerakan syal; pengembangan syal; lumpur dasar air The methyl glucoside drilling fluid, or designated as the MEG, is a recently developed environmentally–friendly water–based mud. It is said to possess performance that approaches the oil–based mud. This project studied on the effects of introducing MEG into sodium chloride (MEG/NaCl) mud in controlling shale hydration and dispersion at different concentrations, namely 5% to 35% by weight, through hot rolling dispersion test, based on the American Petroleum Institute – Recommended Practice – 13I. The inhibitive features were further evaluated against several shale samples which had different reactivity and clay contents. Besides, the performance of MEG/NaCl mud was also evaluated through series of rheological properties, fluid loss, mud water activity, and ageing process tests as recommended in the American Petroleum Institute – Recommended Practice – 13B. The experimental results revealed that MEG/NaCl mud system could satisfactorily exhibit shale stabilization performance. The effective concentration of MEG, however, was corresponding on the reactivity and clay content present in the shale. The experiment results also showed that MEG is a good fluid loss control agent.

AbstractThis work investigates the efficacy of a biodegradable natural product, litchi leaves powder (LLP) as a filtration loss control agent in the water-based drilling fluid formulations. In order to evaluate the potential of litchi leaves powder (LLP), a strict protocol of experimentations according to API (American Petroleum Institute) standard has been followed. The experimental outcome showed that before hot rolling and after hot rolling of mud samples at 100 °C it was observed that 3–5% Concentration of LLP significantly increased the rheological parameters such as PV, YP and gelation of drilling fluid as compared to reference mud. Also, LLP reformed the filtration loss control characterization, suggesting a better biodegradable fluid loss reducing agent. After hot rolling at 100 °C for 18 h, the water-based drilling fluid with LLP as an additive showed a marked reduction in filtration control property as compared to reference Mud (RM). Experimental results concluded that 5% concentration of LLP significantly reduced the filtration loss of drilling fluid by 70.6% as compared to reference mud under the influence of 100 psi pressure. However, the conventional fluid loss additive CMC (LVG) reduced the filtration loss by maximum 67.5% as compared to reference mud. Therefore, LLP can be used as an alternative to CMC (LVG) in water-based drilling fluid with a maximum subsurface temperature of 100 °C.

This paper aimed at improving the water-based drilling mud using Moringa oleifera (M. Oleifera) plant leaves. The rheological properties (plastic viscosity (PV), yield point (YP), and gel strength) of the mud were measured using standard procedures. The mud weight was not affected by M. oleifera concentration (10.03-10.63 pounds per gallon (ppg)). pH of the formulated mud decreased by 28% with increasing concentration of the M. oleifera leaves. The highest PV (33cP) was recorded by mud with 1% M. oleifera leaves at 50ºC while the least value (22cP) was given by control mud at 70ºC temperature. Highest YP (57 1b/100ft2) was recorded by mud sample with 4% concentration of M. oleifera leaves while 1% gave the lowest YP value of 91b/100ft2 at 30ºC and 49ºC respectively.  Gel strength at 10 seconds showed improvement with 2% concentration of leaves by recording maximum of 5 1 b/100 ft2 at 70ºC while the lowest gel strength was recorded by 1% leaves concentration at 49ºC. A good gel strength (30.21 b/100 ft2) at 10 minutes was recorded by mud sample with 3% leaves of M. oleifera at temperature of 30ºC. The results indicated that the M. oleifera leaves significantly improved the rheological properties of the mud. It was also observed that the mud weight of formulated muds with M. oleifera leaves were not affected which leads to stability of the wellbore if the formulation is used.  These great result calls for the need to use M. oleifera leaves to improve rheological properties of the drilling mud. An investigation of M. oleifera as fluid loss control should be done as well as need to carry out isolation and characterization of the active ingredients from M. oleifera leaves so as to establish the compound (s) associated with its activity in drilling mud.

The extent of damage to formation caused by water based drilling mud containing corn cob treated with sodium hydroxide to partially replace polyanionic cellulose (PAC) as a fluid loss control additive has been studied. Core samples were obtained from a well in Niger Delta for this study with a permeameter used to force the drilling mud into core samples at high pressures. Physio-chemical properties (moisture content, cellulose and lignin) of the samples were measured and the result after treatment showed reduction. The corn cob was combined with the PAC in the ratio of 25-75%, 50-50% and 75-25% in the mud. Analyzed drilling mud rheological properties such as plastic viscosity, apparent viscosity, yield point and gel strength all decreased as percentage of corn cob increased in the combination and steadily decreased as temperature increased to 200oF. Measured fluid loss and pH of the mud showed an increase in fluid loss and pH in mud sample with 100% corn cob. The extent of formation damage was determined by the differences in the initial and final permeability of the core samples. Experimental data were used to develop analytical models that can serve as effective tool to predict fluid loss, rheological properties of the drilling mud at temperature up to 200oF and percentage formation damage at 100 psi.

The experimental study was conducted on rheological properties in laboratory to measure the integrity of cement slurry. Three samples were used and analyzed at different parameters to check the elasticity of cement slurry. Additives with various concentrations, i.e. silica fume % BWOC (Present by Weight on Cement) (15, 17, 19 and 21), dispersant % Wt (Percent Weight) (0.21, 0.26 and 0.31) and additional 1; % Wt of fluid losscontrol were used to improve the performance of the cement slurry at the temperature of 123oC. The results have shown that increase in the concentration of dispersants that have caused to decrease in the Plastic Viscosity (PV), Yield Point (YP) and GS (Gel Strength). The rheological properties of cement were improved with the addition of fluid loss control additive in 21 % BWOC (Present by Weight on Cement) silica fume increase the water quantity in cement slurry that improve its durability and to reduce the strength retrogression in High Temperature High Pressure (HTHP) environment. Results were achieved through HTHP OFITE Viscometer (Model 1100).
