Safety On A Drilling Rig: Is It Safety Culture?
<p>Why do workers on a modern offshore drilling rig continue to make decisions leading to unsafe conditions, acts or incidents? In a perfect world, workers in any industry would go to work and come home in the same condition as they started the day: no incidents. Worker injuries and deaths are all …

Modelling and Analysis of the Axial Vibration on BHA of Horizontal Drilling Rig
Horizontal drilling technology is a widely applied well drilling technology due to its capability of reducing drilling time and cost, and at same time increasing the production. In practice, oil and gas production companies employ rotary steerable system or positive displacement motor to steer the …

Probabilistic modelling of oil rig drilling operations for business decision support: a real world application of Bayesian networks and computational intelligence.
… tool for forecasting the performance of rig drilling operations. A prototype for a tool able to forecast the future performance of a drilling operation is created using the obtained data, the statistical model and the experts' domain knowledge. This work makes the following contributions: …

Late-quaternary environmental change at Eastbourne, East Sussex
… investigation, using hand auger and a commercial drilling rig, revealed extensive unconsolidated sediments down to a maximum depth of 33m. which consist of gravels, sand, silt and clay with restricted peat development. The history of the vegetation has been traced back to the Lateglacial when, it …

Tills Underlying the Sediments of Glacial Lake Souris North-Central North Dakota
… Souris basin. The North Dakota Geological Survey drilling rig was used to drill holes, 36 of which penetrated till; a total of 109 samples were collected. Till was characterized on the basis of textural and lithologic analyses, in addition to visual hand-sample descriptions. The textural analyses …

Rock Drilling with impregnated diamond microbits
A fully instrumented laboratory drilling rig was designed and used to drill a variety of rock types with impregnated diamond microbits. The rocks, selected to represent a wide range of properties, were characterised by optical petrography and by the measurement of uniaxial compressive strength and …

Extending the reach of drilling: better wellbore trajectory and torque & drag models
Extended reach [ER] drilling refers to the practice of directionally drilling to a given geological target located at a significant horizontal distance [horizontal departure] from the drilling rig. The ability to perform complex ER operations has become increasingly important in recent years, as …
