Definitive dynamic surveys: A long-awaited engineering innovation

Ross Lowdon, Shadi Altayeb Mussa, Schlumberger

A survey-while-drilling service performs definitive dynamic analysis as the BHA rotates, providing significant rig-time savings compared to conventional static MWD surveys. The ability to see continuous real-time borehole conditions optimizes drilling, reduces risks and eliminates survey-related NPT.

CGG signs multi-client airborne gravity gradient survey agreement with SNPC in Congo

CGG is mobilizing to acquire the industry’s first-ever multi-client airborne gravity and magnetic survey of the onshore Congo Cuvette Basin in the Republic of Congo after signing an agreement with the SNPC and the Ministry of Hydrocarbons.

Integrated diagnostics data advance infill development

Zachary Crowley, Mike Davies, Erica Coenen, Reveal Energy Services

Large-scale data accumulation is becoming more common in shale development. However, the industry struggles with a data dilemma. On the one hand, operators know that they have to gather data to learn and improve. On the other hand, the learning and analysis require so much manpower that often the collected data are left unexplored.

Advanced, process-based geomechanical modeling reduces risk in layered salt basins

Rajesh Goteti, Aramco Americas

Unique geomechanical modeling technique mitigates geological and drilling-related risk in basins with layered evaporite sequences, which are not amenable to traditional structural analysis methods.
