Drilling
Updates about global exploration and production activities and developments.
One major challenge for drilling-fluid engineers is the design and management of optimal drilling-fluid formulations in emerging frontiers—fractured formations and high-pressure geothermal environments. Recently, operators have leveraged cutting-edge technology such as machine learning and expanded data-driven techniques to facilitate the development of new drilling-f…
This research aims to develop a fluid-advisory system that provides recommendations for optimal amounts of chemical additives needed to maintain desired fluid properties in various drilling-fluid systems.

This paper describes a successful U-turn trajectory test in South Texas that has created new economic project opportunities for the company and increased optionality within challenged lease spaces across the field. -
Capitalizing on technology that originated with NASA delivers savings on directional drilling operations.
-
A pilot application using computer vision technology has been created to count and measure the pipe entering the wellbore and detect personnel movement in the red zone during pipe-delivery operations.
-
The authors seek to eliminate the need for pressure testing in the evaluation of annular creep barriers by qualifying the barrier using only cased-hole log measurements.
-
This paper discusses the results of extensive laboratory tests used for the customization of a reservoir drill-in fluid and a delayed breaker—and their field performance—for two deepwater gas-injector wells.

In the October 2021 issue of JPT, incoming SPE President Kamel Ben-Naceur discussed the importance of collaboration in solving technical problems quickly and efficiently. Three of the papers selected in this section are from collaborations between multiple companies pooling their expertise and resources to develop solutions for complex problems that could not be addre…

This paper presents a screenout-classification system based on Gaussian hidden Markov models that predicts screenouts and provides early warning.
-
This paper discusses the results of driller stress tests and the implementation of a system that assists the operator in kick detection, space out, and preparation for well shut-in.
-
The authors describe a laboratory method for measuring cement expansion that has been used to evaluate the total bulk volume change of cement based on curing in a dry environment and in water.
