The Effect of Coconut Fibres, Banana Trunk Peel and Baggasse on the Lost Circulation of the Drilling Mud

Abstract

<p>Lost Circulation Materials (LCM) are specially designed not to damage the penetrating formation during handling of loss circulation problems and are very effective for drilling operations worldwide. Optimization of LCM composition may stop loss circulation effectively and protect the production zone from the invasion of mud filtrate. The concentration of lost circulation materials (LCM) is a key parameter to determine the effectiveness of LCM. In this study, laboratory equipment such as the Hamilton beech mixer, Fann VG meter and API filter press are used to evaluate the effectiveness of various LCMs in dealing with loss circulation. In this research, coconut fibre, banana tree skin, and bagasse are used as LCM in various concentrations. The mud losses were simulated using an 80 mesh shaker. The quality of the muddy rheological properties was<br />the basic parameters to be evaluated. The test was carried out at 80oF and 200oF. The experimental results show that bagasse has the best performance both at 80oF and 200oF as LCM compared withcoconut fibres and banana trunk. The lost circulation of mud filtrate at 80oF and 200oF due to the addition of 2 gram bagasse is 34 ml and 40 ml, respectively.</p>

Laboratory Study: Comparison of Physical Properties of XCD Polymer Drilling Mud and PHPA

“…Drilling fluid or often referred to as drilling mud is a fluid composed of various materials or chemicals that have a very important role in a drilling operation [1]. Drilling mud serves to lift drill cuttings (cutting) to the surface [2], [3]. Drilling mud has physical properties and these physical properties are very influential in determining how optimal the drilling mud is in lifting cuttings [4].…”

Cutting Evaluation of HPWBM Drilling Mud Using CCI, CTR, and CCA Method at 17 ½ inch Hole in Directional Well G, Field S.

“…The main function of this drilling mud is to clean the drill cuttings (hole cleaning) left at the bottom of the borehole so that it rises to the surface, and prevent fluid loss and pressure loss so that the formation pressure and drilling fluid remain stable [4,5]. Therefore, several parameters must be considered from the drilling mud including; density which eISSN: 2614-0268 67 pISSN: 2615-3653 affects the ROP (Rate of Penetration), Rheology (viscosity, yield point, and also plastic viscosity) which affects the speed of removal of drill cuttings, fluid flow rate (flowrate) which affects the direction of flow in the annulus of the borehole [6][7][8][9]. The process of removing cutting or hole cleaning from a drilling operation is divided into three methods where there are CCI (Cutting Carrying Index), CCA (Cutting Capacity Annulus), and CTR (Cutting Transport Ratio).…”
