... Abstract According to the field data, there are several methods to reduce the drilling cost of future wells. One of these methods is the optimization of drilling parameters to obtain the maximum rate of penetration (ROP) in each bit run. Many parameters affect ROP like hole cleaning (including...

... cuttings cleaning efficiency is enhanced and the rate of penetration (ROP) is improved. This paper studied the mechanisms of improving the ROP and cuttings cleaning efficiency in hydraulic pulsed cavitating jet drilling. Hydraulic pulsed cavitating jet drilling technology has been applied in 8 oil fields...

... Abstract This paper presents a new Flexible Bottomhole Assembly (BHA), which is classified as a coupled driven drilling BHA of the power anti-deviation, with the technical superiority of anti-deviation and high ROP. The coupled driven drilling has simultaneously two driving powers: one is from...

... Abstract Estimation of the drilling rate of penetration (ROP) has always been a challenge for drilling engineers, since it is the key parameter in drilling optimization. There are many parameters which have significant influence on ROP. Relating penetration rate to these parameters result...

... is hardness of the formation which can help us choosing proper bit. So we can have a comparison between two methods and check the answers with history drilling data of field. neural network bit selection cost analysis well logging genetic algorithm spe paper selection machine learning rop bit...

... and thermal fatigue. Thus, cutter technology has been the limiting factor for efficient PDC bit drilling in the East Texas Basin. Recent technological developments have produced a new, highly abrasion resistant cutter that has increased rate of penetration (ROP) and total footage drilled in addition...

... as ‘tragic peak’ during conventional drilling operations because the sandstone is hard and abrasive in nature, leading to extreme low rate of penetration (ROP). Air Drilling technology was utilized to increase the ROP through the formation at depths of 10,000 ft (3,047m) and greater. The deep exploration...

... to the platform. A seven-month typhoon season brings an average of four typhoons through the field each year. Operations must be suspended for an average of 5 days during these storms. Typical drilling equipment used on the majority of past wells includes: mcnair rop minimum horizontal stress...

... which affect deviation and rate of penetration (ROP): side force on bit, tilted angle of bit and formation deflection force and weight on bit (WOB). The mechanism of hole deviation control, namely the proper treatment of relationship between side force of bit and formation force, is discussed...
