Drilling
Two new wells add 15,000 BOE/D of peak capacity to the London-based supermajor's North Sea production profile.
This paper expands the understanding of geopolymer/microsphere interactions and presents design considerations for alternative cementing materials under low-temperature regimes.
Digitalization and advanced analytics have enabled drilling automation that is changing the way wells are executed to deliver more production earlier.

Enhancement to the drillship comes ahead of work commitment on Shell's Sparta development in the US Gulf of Mexico, its first in the Gulf to produce from 20K reservoirs. -
Derived from the principles of radial jet drilling, a new technology called micro-turbine drilling is developed to allow for drilling of micro-sidetracks from cased boreholes in very hard reservoir rock.

This paper details a gravel packing operation in the Martin Linge field in the North Sea that marks the highest density carrier fluid openhole gravel pack completed successfully worldwide, setting a new standard for well completions in challenging high-pressure environments.
-
The tie between US crude output and key indicators such as rig counts and the number of new wells has significantly weakened.
-
Majors and independents alike are targeting high-impact wells across the globe to boost future oil and gas production volumes.
-
This paper presents the mitigation of drilling challenges encountered in the Niger Delta through a technique that relates shale resistivity to shale porosity and vertical effective stress to predict pore pressure.
-
This work provides a new modeling tool, validated against a static-wellbore solver and field data, to estimate and manage downhole temperature in higher-temperature oil, gas, and geothermal wells.

This paper describes results of a study indicating that an enzyme/in-situ organic acid generated cleanup system was effective at degrading filter cake for a water-based-mud field sample, reflected in the obtained return permeability of nearly 83%.

The Research Council of Norway’s $118,000 grant will support development of longer fishbone laterals to raise production while lowering carbon footprints.
-
The effects of aging and temperature on the performance of one-part “just add water” granite based geopolymers are studied for application in well cementing and abandonment. Further studied is the role of zinc as a strength enhancer over a long curing period.
