Drilling
This study identifies critical knowledge gaps in wellbore integrity and underscores areas that require further investigation, providing insights into how wellbores must evolve to meet the technical demands of the energy transition.
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.
-
This paper focuses on the preparation for, and implementation of, well-control training, while highlighting the integration of people skills into curricula and what advantages operators and drilling contractors have obtained. -
This paper describes the mobilization of a snubbing unit and blowout preventer (BOP) stack in the Middle East that enabled a well with an underground blowout and surface broaching to be brought under control within a short time.
-
Directional drilling and measurement-while-drilling technology has become so democratized in the Texas shale sector that no provider holds more than 8% of the market share.
-
Three appraisal wells drilled this year—GTA-1, Yakaar-2, and Orca-1—targeted nine hydrocarbon-bearing zones, encountering gas in high-quality reservoirs in all zones and yielding a combined 160 m of net pay.
-
Under the agreement, the Oklahoma City independent will monetize half of its working interest in 133 undrilled locations in the form of a $100-million drilling carry during the next 4 years.
-
Calgary-based Colombia producers Canacol Energy and Parex Resources led all firms by gaining three blocks each, with one more counteroffer from Parex pending review.
-
Industry awaits the results of Apache’s Maka Central-1 exploratory well offshore Suriname, where high expectations follow the rapid exploration success of neighboring Guyana.
-
This paper compares the performance of three mature-field horizontal infill wells, one of which is completed with autonomous inflow-control devices (AICDs).
-
Multistage horizontal well designs were first implemented in the Bakken in 2007. Since then, more than 12,000 wells have been completed in either the Middle Bakken or Three Forks zones.
-
A new 3D drillstring model determines the static and dynamic behavior of bottomhole assemblies (BHAs) in realistic wellbores.
