geosteering
-
Geosteering is supposed to ensure the wellbore stays in the most-productive zone, but a recent study suggests it often misses the mark. -
Moving their directional drillers into their Houston real-time remote operations centers has improved drilling efficiency for two of the top shale producers.
-
This paper presents an interdisciplinary approach to the description of tectonic dislocations made on the basis of interpretation of seismic data, petrophysical analysis of well-logging data in horizontal wells, and inversion of a multifrequency propagation tool. -
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).
-
The use of intelligent software is on the rise in the industry and it is changing how engineers approach problems. A series of articles explores the potential benefits and limitations of this emerging area of data science.
-
A new multilayer boundary‑detection service has been introduced to resolve the geological uncertainty associated with horizontal wells in Bohai Bay. Geosteering and real time reservoir characterization were used to reduce the uncertainty.
-
The standard for progress in shale development has been the drastic reduction in the number of days needed to drill a well, from more than 20 to less than 5 in some unconventional plays. But some question whether it has become a misleading metric for an industry needing more productive wells.
-
This paper describes placement of horizontal wells in this kind of heterogeneous reservoir through an integrated approach.
-
The Nini East field represents a significant drilling challenge.
