Title
(EN) TETHERED DRONE FOR DOWNHOLE OIL AND GAS WELLBORE OPERATIONS
(FR) DRONE AMARRÉ POUR OPÉRATIONS DE PUITS DE FORAGE DE PÉTROLE ET DE GAZ EN CONDITIONS DE FOND DE TROU
Abstract
(EN)
According to some embodiments, devices, systems, and methods for conveying downhole oil and gas wellbore tools and performing downhole oil and gas wellbore operations are disclosed. The exemplary devices, systems, and methods may include a tethered drone that substantially disintegrates and/or dissolves into a proppant when shaped charges that the tethered drone carries are detonated. Two or more tethered drones, wellbore tools, and/or data collection devices may be connected in a tethered drone string for efficiently performing wellbore operations and reducing the amount of debris left in the wellbore after such operations.
(FR)
La présente invention concerne, selon certains modes de réalisation, des dispositifs, des systèmes et des procédés pour transporter des outils de puits de forage de pétrole et de gaz en conditions de fond et effectuer des opérations de puits de forage de pétrole et de gaz en conditions de fond de trou. Les dispositifs, systèmes et procédés donnés à titre d'exemple peuvent comprendre un drone amarré qui se désintègre et/ou se dissout sensiblement dans un agent de soutènement lorsque des charges creuses portées par le drone explosent. Au moins deux drones amarrés, des outils de puits de forage et/ou des dispositifs de collecte de données peuvent être connectés à un drone amarré pour effectuer efficacement des opérations de puits de forage et réduire la quantité de débris laissés dans le puits de forage après de telles opérations.
