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.
Updates about global exploration and production activities and developments.
One major challenge for drilling-fluid engineers is the design and management of optimal drilling-fluid formulations in emerging frontiers—fractured formations and high-pressure geothermal environments. Recently, operators have leveraged cutting-edge technology such as machine learning and expanded data-driven techniques to facilitate the development of new drilling-f…

This paper presents the results of an experimental and modeling study that demonstrates the existence of severe slugging in systems with upward-inclined lateral flow paths, such as a toe-down well. -
The Esox-1 well encountered 58 m of high-quality oil-bearing Miocene reservoirs and will be tied back to Tubular Bells production facilities.
-
The Orca-1 and Marsouin-1 wells have derisked up to 50 Tcf of gas initially in place from the Cenomanian and Albian plays in the BirAllah area, more than sufficient to support a world-scale LNG project, partner Kosmos Energy said.

The Sidri 36 appraisal well confirmed the downdip westward extension of the Sidri 23 discovery announced last July by the Italian major.
-
India’s ONGC reported an oil find in Colombia’s Llanos Basin as well as a gas and oil discovery in Brazil’s deepwater Sergipe Alagoas Basin.
-
Development of the Tolmount East discovery will be fast-tracked, the operator said.
-
The field is estimated to hold 19 Tcf, of which 13 Tcf is recoverable, NIOC reported 14 October.
-
Santos Energy said its second and final flow test from the Dorado field suggests potential flow rates of around 30,000 B/D from each Caley reservoir production well.
-
The hybrid power technology cuts fuel consumption and boosts the dynamically positioned rig’s station-keeping reliability, the drilling contractor says.
-
Measured-pressure approaches have offered much promise for some time but have been slow to reach widespread application. A spate of technical developments, deployments, trials, and applications, however, recently has pushed measured-pressure drilling and its nuanced variants to their full potential.
