... configurations are often used to replace legacy round cutters on an existing drill bit cutting structure to optimize the drilling performance of the bit. This alteration is frequently implemented without careful consideration of the existing secondary elements, which may prevent the realization of the full...

... describes the collaboration of the drilling provider with client's wells drilling delivery team, in the planning, risk assessment, and formation evaluation solutions for drilling performance from spud to well Total Depth (TD) for three wells in Phase 1 of this campaign. The remaining three wells are planned...

... process for optimizing performance was developed. After 6 wells, optimal operating ranges were identified. This process leads the driller to respond to changes in formation and deliver more consistent drilling performance with excellent results. ROP increased from 50m/hr to 150m/hr, driven by improved ROP...

... Abstract Operators in the current volatile oil and gas industry must optimise drilling performance and minimize well cost. Various drilling tools and methods have been implemented over the years to improve drilling efficiency and to reduce the non-productive time (NPT) while drilling through...

... by an efficient selection and placement of drill string components. This approach has enabled to outperform past drilling performance and has become the norm in similar fields in southern Iraq. stabilizer drilling performance BHA Upstream Oil & Gas well 1 ROP high torque software breakthrough...

... Abstract Due to the high number of wells required, drilling costs are a significant factor for coal seam gas developments. In order to improve drilling performance (and reduce associated costs) current performance should be analysed to identify areas with potential for improvement. This study...

... are increasingly using data analytics to improve drilling performance. This paper provides an example of using a business intelligence (BI) tool to analyze drilling data in the Permian Basin. The BI tool helped to improve operation decisions through the use of a visual report. A database, consisting of massive...

... with both fluid types. The analyses include mud chemistry, drilling days, mud weight and well architectures such as hole sizes and casing sizes as well as depths of the casing shoe. A statistical analysis of drilling performance (P10, P50, and P90) was also performed to evaluate drilling days for wells...

..., over gauge wellbore. Traditionally positive displacement motor (PDM) bottom hole assemblies (BHAs) were used to directionally drill in these difficult hole conditions. Drilling performance was far from ideal. Steering penetration rates were typically 50–80% less than those obtained when rotating, even...

... Abstract Improving drilling performance leading to reduction in Well drilling time and the associated costs, without compromising the deliverability of the Well, is the primary objective of drilling engineering. Some of the major challenges faced by Drilling Engineers include damage to the pay...
