An automated detection application helped identify stringers early for an operator of a mature field in the North Sea while drilling multilateral wells through reservoir sections containing hard calcite stringers interspersed in sand formations with low unconfined compressive strength. The application guided drilling decisions that minimized invisible lost time and sh…

An emissions-reduction study conducted for a Middle East operator identified potential annual savings of $10 million–$15 million, a 20% decrease in total Scope 1 CO2eq emissions, and 10 MW of energy reduction and delivered more than 100 recommendations for both technical and internal framework improvements.

Zachry Industrial highlights the benefits of using advanced modeling to plan the construction to update the $10 billion Golden Pass LNG from an import terminal to an import/export terminal, connecting thousands of project participants during COVID-19 lockdowns.

Managed-pressure drilling has been associated as a technology used only on problematic wells and only as a last resort. However, when integrated at the beginning of operations as part of a comprehensive well plan, it becomes a performance-enhancing solution for any type of well classification, including development, directional, multilaterals, and horizontals.

Capitalizing on technology that originated with NASA delivers savings on directional drilling operations.

Carbonate reservoirs require effective acid stimulation to improve well productivity. For long horizontal wells, a complicating factor has previously been the difficulty of controlling acid placement along the reservoir section. The Smart Liner concept uses a number of small holes spaced in such a way so as to distribute the acid evenly along the reservoir interval.

The study assessed the CO2 footprint and NO2 emissions for different drill-cuttings treatment alternatives. The values were then used to create an emissions calculator that can be applied to projects to clarify the actual potential for emissions reduction within the drilling-waste-management process.

A rigless chemical frac-hit remediation process was designed to address the damage mechanisms of capillary phase trapping, reduced hydrocarbon relative permeability, paraffin deposition, and minor scale deposition.
