Abstract

Quantitative analysis of cutting removal used in this study uses three methods, namely Cutting Carry Index, Cutting Transport Ratio, and Cutting Concentration in Annulus. This method is used to determine whether the composition of the mud used is maximal or not, starting from the maximum content of solids that can be carried in 1 gal to the viscosity and also the flow pattern of the fluid in order to successfully bring the cutting to the surface. Where these three methods have standardization to determine the cutting can be lifted, including for the cutting carry index method the value must be more than 1, for the cutting transport ratio the value must be greater than 50%, and for cutting concentration in annulus the value must be less than 5%. After analyzing the lifting using the three methods above, it can be seen the parameters in the successful removal of the cutting. These parameters include the physical properties of the fluid which includes the value of density, plastic viscosity, and also the yield point, while other parameters such as drill bit speed, mudflow velocity, cutting diameter are also important parameters in a successful borehole lifting. From the observations of this study, we can conclude that the use of mud in well G field S has been running optimally. The calculation of cutting lift has met the standardization limits. This study also carried out sensitivity analysis as a source of future literature, so that sensitivity analysis parameters can be used if you want to do a well development. This study shows an analysis of cutting lift on a 17.5 inch Route at a depth of 825ft - 2581ft, with an average drilling slope of 4 degrees per 100 ft.

Abstract

The evaluation of hydraulics carried out in a trajectory namely 17 ½ inches provides an overview of the hydraulic problems that occur with less-than-optimal pressure in the bit because it is less than the minimum percentage value that should be. which is less than 50%. it is affected by factors such as flow rate. mud weight. the rheology of the mud used and pressure loss both in the surface and sub-surface such as bit. pipe and annulus. So, optimization with the BHHP (Bit Hydraulic Horse Power) method becomes the next step to be taken in order for the drilling operation can perform better. It has been found from the optimization results that the CTR (Cutting Transport Ratio) method is a cutting analysis method that demonstrates the correct performance of the cutting transport process if the minimum percentage of 50% or higher is met. In addition, this method also takes the angle of inclination of a directional well Y-1 into one of the considerations. On the first trajectory. 17 ½ inch hole (1338.58 – 3166.01 ft) the pressure in the bit increased from around 22.83% to 31.14% at the initial condition to 56.20% until 56.59% with cutting transport results after being optimized up to 99%. The use of the BHHP (Bit Hydraulic Horse Power) method to optimize drilling hydraulics in the directional well is said to be successful because it produces an optimization value that is greater than the minimum standard which is 50%. Furthermore, the CTR (Cutting Transport Ratio) method to analyze the transport of cuttings to the surface has been running well showing the results that the cuttings have been successfully transported to the surface. Therefore, this method can be said to be successful with the acquisition of a value percentage above 50%.
