Drilling/completion fluids
Two critical facets of the discipline of well control and wellbore integrity—decarbonization and groundbreaking automation of essential processes—are highlighted in the three primary paper selections presented at SPE and SPE-affiliated conferences during the past year.
This paper describes development of a high-temperature water-based reservoir drill-in fluid using a novel synthetic polymer and customized with optimal chemical concentrations and sized calcium carbonate.
In this case study, a geomechanics-based approach was used to create bridging and sealing at the fracture aperture using a biparticle self-degradable lost-circulation-fluid system.

Despite hostile wellbore conditions, an operations team overcame challenges of drilling-fluid design and management to drill the first ultrahigh-pressure/high-temperature (HP/HT), deep-gas well offshore Malay Peninsula. -
In an effort to optimize drilling operations and economics, an operator examined the effect of adding hollow glass spheres (HGSs) directly to the drilling fluid instead of performing underbalanced drilling.
-
The strength and conductivity of proppant packs are key parameters for assessing their performance. This paper introduces a new analysis technique based on interpretation of acoustic measurements to quantify mechanical damage in propping agents.
-
This paper presents experimental research in which a significant fracture-pressure increase was achieved in shale and the predominant wellbore strenghtening mechanism was identified.
-
Technology developers are working on a new ultrasonic flowmeter for drilling fluids aimed at obtaining better measurements than current systems with far fewer disruptions to rig systems.
-
This paper discusses the laboratory evaluation of potential high-pressure/high-temperature (HP/HT) drilling-fluid designs considered for a deep gas exploration well in Malaysia.
-
Mutual understanding and respect when universities collaborate with industry is crucial. A clear policy on harmonizing innovation and higher education should be created. However, caution must be taken not to have a one-size-fits-all approach.
-
This paper describes the first application of clay-free IEFs in the Norwegian continental shelf (NCS), with an emphasis on an impressively low and consistent ECD contribution.
-
Making hole has become a more difficult and complex operation as operators move into untapped horizons, especially deepwater and unconventional fields.
-
This paper describes the evaluation of a nanofluid containing nanomaterials with high adsorption capacity used for asphaltene inhibition in the volatile Cupiagua Sur oil field in Colombia.
