Drilling
The London-headquartered independent acquires position in the US Gulf while preparing Zama for final investment decision.
This study illustrates the new capabilities, tailored for CO₂ storage applications, of a modeling framework that provides a quantitative, risk-based assessment of the long-term integrity of legacy plugged and abandoned wells.
Two critical facets of the discipline of well control and wellbore integrity—decarbonization and groundbreaking automation of essential processes—are highlighted in the three primary paper selections presented at SPE and SPE-affiliated conferences during the past year.
-
Production and drawdown data from 10 subsea deepwater fractured wells have been modeled with an analytical model for unsteady-state flow with fines migration. -
The paper presents a new approach that uses X-ray-microcomputed-tomography (micro-CT) scanning to produce high-resolution data of entire core samples.
-
An ongoing research project started nearly 3 years ago by the US Department of Energy’s National Energy Technology Laboratory (NETL) is shedding new light on what really happens to foamed cement as it is pumped deep down offshore wells during completions.
-
This is an update on several managed-pressure drilling (MPD) technologies and downhole drilling performance-enhancing tools in use onshore and is the first of a two-part series. The second article on offshore MPD technologies will appear in the February issue of JPT.
-
A scientist hired by federal regulators to look for ways to reduce the risk of well blowouts said it is time for the oil and gas industry to treat kicks taken while drilling the same way doctors treat heart attacks.
-
A 100% fully mechanical rotary-steerable tool has been developed specifically for the high-volume drilling market, providing full 3D directional control while under full rotation of the drillstring from surface.
-
The recent introduction of a new rolling-cutter polycrystalline-diamond-compact (PDC) bit that uses 360° of the diamond edge has delivered positive results in field trials.
-
Conventional drilling through lower intermediate intervals in the southern portion of the Alpine field on Alaska’s North Slope has posed significant challenges.
-
Making hole has become a more difficult and complex operation as operators move into untapped horizons, especially deepwater and unconventional fields.
-
Horizontal- or complex-geometry-well construction projects are potentially good candidates to work out new contractual arrangements. Authorization to proceed with these projects is technically based, and measurable key variables can be defined.
