Title: Evaluation of Wheat Husk as Environment Friendly Fluid Loss Additive as a Substitute of CMC(LVG) in Water based Drilling Fluid up to 100°C. Authors: Althamas Yaseer; Mubarak Khan; Shaik Abdul Mugni; Malavika Reddy Kummetha; Ved Prakash Abstract: Filtration control is an important property of a drilling fluid particularly while drilling through the permeable formations. This property of a drilling mud is obtained or enhanced using various additives. Currently organic polymers are commonly used as additives to control filtrate loss in water based drilling mud and exhibits negative impacts on the environment when released, hence there is a tremendous need for new environmental friendly, biodegradable additives which can help in controlling filtration loss with least effect on environment and also on worker's health. This study involves the introduction of environmental friendly food waste product i.e. "wheat husk powder" (WHP) as a filtration loss additive. The effects of various concentration of WHP on physical and chemical properties of a mud such as mud weight, pH, PV, AV, YP, gel strength, filtration loss (API), BHR and AHR rheological properties were evaluated and all the results were compared with the properties of the reference mud prepared with the conventionally used filtration loss additive CMC (LVG) in order to asses and validate the effectiveness of WHP in optimizing the performance of drilling mud. The results obtained showed that WHP was behaving as a filtration loss reducer and the drilling mud prepared with WHP was thermally stable at up to 100 0C. Hence WHP is successful replacement of CMC (LVG) in aspect of cost effectiveness, filtration loss reduction, environmental friendly and thermal stability.

Title: Use of Sodium Lignosulphonate in Aqueous Drilling Fluid System for Mud Property Enhancement Authors: Mohmad Afzal Mohmad Sidik; Azfarhaad Kadri; Rishabh Raj; Bhairab Jyoti Gogoi Abstract: Sodium Lignosulphonate (SLS) is yellowish brown powder which is completely soluble in water. It is an anionic surfactant with high molecular weight polymer. It is also rich in sulfo and carboxyl group and has better water-solubility, surfactivity and dispersion capacity. Sodium Lignosulphonate is stable at high temperatures ranging from (150 °F to 250 °F) which occur in well bores during drilling. It acts as a deflocculant which prevents coagulation of bentonite and also as a stabilizer to stabilize emulsions and as thinning agent in drilling fluids. In this study SLS is used as an additive in aqueous drilling fluids and its results are compared with other drilling fluid samples of different compositions.

Title: Validation of Apparent Viscosity Formula using Different Drilling Fluid Samples Authors: Mohmad Afzal Mohmad Sidik; Azfarhaad Kadri; Rishabh Raj; Bhairab Jyoti Gogoi Abstract: A Marsh Funnel is a simple device which uses a simple technique to measure the apparent viscosity of a drilling fluid. In this experiment we will validate M.J Pitts and Faleh H. M. Almahdawis formula for apparent viscosity, i.e., μeff = ρ (t - 25) and μapp = ρ (t - 28) respectively, where μapp = apparent viscosity in centipoise, ρ = density in g/cm³, t = quart funnel time in seconds. To validate we will check the apparent viscosity of a drilling fluid using a marsh funnel and a hand crank viscometer and compare the reading gained using the above formula and the reading from the hand crank viscometer. By this method we will be able to check which of the above two formula is more accurate and suitable for checking the apparent viscosity of a drilling fluid. The drilling fluid prepared will contain different types of additives to ensure that the formula will be applicable for a variety of drilling fluids.

Title: Use of Bamboo Leaf Ash as an Additive to Aqueous Drilling Fluid and Study the Variation of Rheological and Filtration Loss Properties Authors: Gautham V Nairy; Mohammed Farhan Jameel; Mariam Susan Matthew; Anushka U N; Bhairab Jyoti Gogoi Abstract: Requisition of efficient use of imprudent by-products for the enhancement of drilling fluid is preferentially beneficial for a hassle-free and relentless drilling process. Intricately designed drilling fluids have been used in the petroleum industry having significant properties to meet many operational requirements. The conventional methods are proven to be efficient in the current scenario, but they have limited capability and may not be suitable for future drilling operations due to the increasing challenges in the petroleum industry. A need exists for a strong, stable and customizable fluid which can not only satisfy the basic functions of a drilling mud, but also make productive use of waste products for its enhancement. This paper deals with the possibility of using Bamboo Leaf Ash (BLA) as an additive in Water Based Drilling Fluid (WBDF). The main components of BLA include silica (SiO2), aluminum (Al2O3) and iron oxide (Fe2O3). The yield percentage of silica from bamboo leaf ash is 78%. In our study we have attempted to use BLA as an additive to WBDF comparative analysis of the rheological properties of drilling fluids with different percentage of BLA has been studied. Based on the comparative study it is observed that BLA can be used as an additive to WBDF.
