A method and system for drilling a wellbore is described. The syste includes a wellbore with a variable density drilling mud, drilling pipe, a bottom hol assembly disposed in the wellbore and a drilling mud processing unit in flui communication with the wellbore. The variable density drilling mud has compressibl particles and drilling fluid. The bottom hole assembly is coupled to the drilling pipe while the drilling mud processing unit is configured to separate the compressibl particles from the variable density drilling mud. The compressible particles in thi embodiment may include compressible hollow objects filled with pressurized gas an configured to maintain the mud weight between the fracture pressure gradient an the pore pressure gradient. In addition, the system and method may also manag the use of compressible particles having different characteristics, such as size, during the drilling operations.

La présente invention concerne un procédé et un système pour forer un forage. Le système comprend un forage avec une boue de forage de densité variable, une tige de forage, un assemblage de fond de trou disposé dans le forage et une unité de traitement de boue de forage en communication fluide avec le forage. La boue de forage de densité variable comporte des particules compressibles et un fluide de forage. L'assemblage de fond de trou est couplé à la tige de forage, alors que l'unité de traitement de boue de forage est configurée pour séparer les particules compressibles à partir de la boue de forage de densité variable. Les particules compressibles dans ce mode de réalisation peuvent comprendre des objets creux compressibles remplis avec un gaz sous pression et configurés pour maintenir le poids de boue entre le gradient de pression de fracture et le gradient de pression de pore. En outre, le système et le procédé peuvent également gérer l'utilisation de particules compressibles qui possèdent différentes caractéristiques, telles que la taille, au cours des opérations de forage.
