Drilling
The Essington-1 well is the first discovery in the Otway since 2021.
Ranger acquires American Well Services for $90.5 million, adding 39 workover rigs and boosting its fleet by 25%.
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.
-
Operators face a dilemma in balancing the need for mud weight (MW) to remain below the fracture gradient to avoid losses, while also providing sufficient density to block influxes into the well. -
Recent research shows that, in addition to hardness, other rock properties, such as lithology types, heterogeneity, and abrasiveness, have equal importance in bit evaluations. Consequently, the discussion must move from rock-strength analysis to rock-drillability analysis.
-
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.
