Drilling
Geophysicist Markos Sourial discusses advances in seismic imaging, the challenges of modern data processing, and what they mean for the next wave of subsurface professionals.
This research aims to develop a fluid-advisory system that provides recommendations for optimal amounts of chemical additives needed to maintain desired fluid properties in various drilling-fluid systems.
This paper describes development of a high-temperature water-based reservoir drill-in fluid using a novel synthetic polymer and customized with optimal chemical concentrations and sized calcium carbonate.

Using log data from offset wells, a bit-selection software based on unconfined compressive strength (UCMPS) calculations has been used to optimize the bit selection for Well X. -
This paper will show how stick/slip vibration distributions can be used to guide drillstring and parameter redesign to mitigate stick/slip in the next well.
-
Severe bit damage is an issue in West Texas land drilling because of abrasive sand formation and interbedded hard stringers.

Helmerich & Payne’s first 100 years have required constant reinvention. Now the company hopes its new drilling software platform built on the acquisitions of two startups will propel it through the next century.

Visuray is using its unique X-ray technology to improve downhole imaging.
-
This paper demonstrates a work flow to determine optimal lateral lengths and trajectories in the Midland Basin by studying the effect of the lateral length and trajectory on well production.
-
This paper presents an approach to modeling the cuttings-lag-depth distribution caused by the dispersion of cuttings-transport velocity in directional drilling.
-
This paper describes a new approach to evaluating the effectiveness of the rotary-steerable-system (RSS) steering mechanism on wellbore tortuosity in horizontal wells.
-
The shift toward lower prices in the industry has resulted in the necessity for more wells to be drilled at lower cost. Numerous other industries have shown that they are able to constantly reduce cost per unit. Where do we stand today and what will the future possibly look like?
-
With the arrival and development of rotary steerable systems in the late 1990s, the industry thought that drilling a perfectly smooth and controlled trajectory would not be an issue. Two decades later, we’re still talking about wellbore quality, especially with long and complex horizontal wells.
