... running speeds of Wells A and B were faster than the three non-HCT utilized wells ( figure 6 ) and this was attributed mainly to the good hole cleaning conditions of the wellbores due to the improved cutting removal action of the HCTs. Comparing Key Performance Indicators for drilling the 12 ¼" hole...

... the expected ECD will be throughout the interval, and can compare this with PWD, Hole Cleaning and ROP analyses.   ECD(SG) = MW + Frictional Losses(psi)/1.442x TVD(m) ECD(ppg) = MW + Frictional Losses(psi)/0.052 × TVD(m)   In order to understand how the cuttings generated while drilling...

.... For these fields the margins are less and a significant focus is put on cost efficient solutions. In many cases, the need for casing cleaning in conjunction with displacement of drilling fluids is questioned. The current paper are reviewing in detail the results from drilling fluids displacement and cased hole...

... Abstract During drilling operation, as inclination of well deviates from zero degree in vertical parts to 90 degree in horizontal and extended reach wells, hole cleaning and cutting removal condition imposes more influence on drilling performance and encountering associated problems with poor...

... Abstract With increasing measured depths and horizontal displacements in extended-reach (ERD) wells, good hole cleaning and cuttings removal remains a major challenge. Poor hole cleaning may result in lost circulation, hinder the casing or liner to be run into its selected position, excessive...

... weight polymers have been reduced and exchanged with low molecular weight polymers to enhance hole cleaning throughout the last years. Fewer cuttings are entrapped in beds down hole and are transported up to the surface. The current paper demonstrates how this low viscous/low gel strength drilling fluid...

... Abstract Machine learning (ML) has become a robust method for modeling field operations based on measurements. For example, wellbore cleanout is a critical operation that needs to be optimized to enhance the removal of solids to reduce problems associated with poor hole cleaning. However...

... Abstract Monitoring of Equivalent Circulating Density (ECD) may improve assessment of potential bad hole cleaning conditions if calculated and measured sufficiently accurately. Machine learning (ML) models can be used for predicting ECD integrating both along-string and surface drilling...

... Abstract Up to 80% of stuck pipe events are hole cleaning related in the case of high-angle wells. Therefore, significant attention should be given to understanding hole cleaning as it is crucial to restricting stuck pipe-related non-productive time (NPT). In order to optimize hole cleaning...

... Abstract Steady-state hole-cleaning models used to monitor cuttings during well construction rely on static parameters that portrait specific drilling scenarios disconnected from each other. This paper presents the integration of transient hole-cleaning models validated in the field...

... performance, hole cleaning, and wellbore stability. This Proof of Concept (PoC) test was conducted over five months on two drilling operations in the Marcellus shale, using three different camera types placed in two shaker locations. Over 200,000ft of video data from 11 wells were collected from the West...

...Discussion of Factors Affecting Cuttings Concentration Drill Pipe Rotation and Eccentricity: Rotation produces a velocity profile difference that facilitates hole cleaning, depending on the fluid rheology and drill string rotating speed ( Nguyen et al. 2010 ; Sanchez 1997 ). Nguyen suggests...

... Averting of this bottleneck is highly needed as it will considerably facilitate the ease of rating drilling muds in terms of their hole cleaning performance even before going into the drilling operations. This research is aimed at developing a model equation for calculating mud carrying ability...

... for successfully hole cleaning with the present drilling parameters for on-bottom operations, and an estimate of the time remaining to clean the wellbore of all cuttings with the current operating parameters for off-bottom operations. Hole cleaning physics-based models must encompass a diverse set of phenomena...

... Abstract Hole cleaning efficiency is one of the major factors that affects well drilling performance. Rate of penetration (ROP) is highly dependent on hole cleaning efficiency. Hole cleaning performance can be monitored in real-time in order to make sure drilled cuttings generated...
