Drilling
As managed pressure drilling gains traction, its principles are influencing a wider range of well-construction activities.
This paper presents laboratory-testing methods and evaluation criteria designed to improve understanding of both the origin and extent of formation damage associated with CO2 injection.
This work introduces an analytical model for nonisothermal CO2 injection that accounts for both Joule-Thomson cooling and interformation heat exchange.

This work presents a systematic geosteering work flow that automatically integrates a priori information and real-time measurements to update geomodels with uncertainties and uses the latest model predictions in a decision-support system (DSS). -
A marked change from a decade ago, Appalachia, the Permian, and the Haynesville now represent almost half of total US gas production, EIA reports.
-
A new report shows a 16% increase fueled by longer lateral lengths and horizontal drilling activity out of the Permian Basin. Continued gains in these areas should bode well for the future, but other factors may play into the market’s performance.
-
Shale explorers run very few logs into horizontal wells, making it difficult to understand the effects of reservoir depletion in tightly spaced wells. This new technology is trying to change that.
-
Range Resources' drilling head talks about how the company went from drilling the shortest laterals in the Marcellus to the longest and why.
-
This paper compares the results of gas identification and lithology identification using pulsed-neutron spectroscopy in openhole and casedhole environments.
-
Today’s advancements in unconventional technology are worth marveling over, but there is still plenty of room for growth.
-
Just 2 months after issuing more than a hundred licenses, the Oil and Gas Authority begins the process again for a whole new set of blocks.
-
SPE is presenting a workshop to further understanding of HSE in drilling operations and sharpen knowledge of industry best practices.

The Apollonia tight-gas chalk play is located in the Abu Gharadig Basin in the Western Desert of Egypt. This has long been ignored as a gas play in the overburden, while the Jurassic and Cretaceous oil fields deeper in the basin have been explored and developed.
