Operational field procedure for identifying, installing and optimizing a gas lift well

John Martinez, Frank E. Ashford, Wes Wright

This article reviews gas lift well selection and its inflow relationship with the reservoir; wellbore and facility parameters that must be addressed; unloading control (kill) fluid that is in the wellbore following all interventions to install downhole equipment; the optimization procedure; and more.

Processing of a large offshore 3DVSP DAS survey in a producing well

Francesco Miranda, Emmanuel Spadavecchia, Shujaat Ali, Roberto Castañeda-Aguilar

DAS fiber deployed on several wells’ completion strings offshore recorded a 3DVSP survey with ongoing production, but with significant noise encountered. A novel, two-step approach on one well addressed fiber directivity response on recorded data to recover relative amplitudes. The final 3D VSP image showed improved spatial resolution over target intervals.

Artificial intelligence for automating seismic horizon selection

Norman Mark

Fully automated seismic horizon picking dramatically shortens times between acquiring seismic data and defining drilling targets. Operators spend millions of man-hours interpreting seismic data to produce viable prospects. Freeing up time to better incorporate G&G properties within mapped structures enhances probabilities of discovering commercial pay.
