Abstract
A system includes a wellbore, a primary tunnel. a jetting sub, a jetting needle, and a secondary tunnel. The wellbore is drilled into a formation. The primary tunnel is formed from the wellbore. The jetting sub is disposed within the primary tunnel. The jetting needle is connected to the jetting sub. The jetting needle is configured to jut out from the jetting sub to penetrate the formation when exposed to a pressure differential. The secondary tunnel is formed from the primary tunnel by a high-pressure jet of fluid exiting the jetting needle into the formation.
Claims20
A system comprising:
- a wellbore drilled into a formation;
- a primary tunnel formed from the wellbore;
- a jetting sub disposed within the primary tunnel;
- a jetting needle connected to the jetting sub, wherein the jetting needle is configured to jut out from the jetting sub to penetrate the formation when exposed to a pressure differential;
- and
- a secondary tunnel formed from the primary tunnel by a high-pressure jet of fluid exiting the jetting needle into the formation.
A system comprising:
- a wellbore drilled into a formation;
- a primary tunnel formed from the wellbore;
- a drilling sub disposed within the primary tunnel;
- a drilling needle having a drill bit and connected to the drilling sub, wherein the drill bit juts out from the drilling sub when a pressure differential is seen on the drilling needle;
- a turbine located within the drilling needle, wherein the turbine rotates the drill bit using fluid pressure;
- and
- a secondary tunnel drilled from the primary tunnel using the rotation of the drill bit.
A method comprising:
- drilling a wellbore into a formation;
- forming a primary tunnel from the wellbore;
- disposing a sub into the primary tunnel;
- extending a needle from the sub into the formation;
- and
- forming a secondary tunnel, from the primary tunnel, using the needle.
