Abstract

A method includes drilling a wellbore and deploying a logging string including a jet nozzle and an anchor in the wellbore. The method includes hydraulically coupling a jetting treatment system including a mud treatment system to a mud circulation system, hydraulically coupling a drilling mud including wellbore fluids to the mud circulation system, and hydraulically coupling the mud circulation system to a drill string bore of the drill string. The method includes activating the jetting treatment system to circulate the drilling mud in the mud treatment system. The method includes circulating in the wellbore, using the jetting treatment system, a treatment mud, disposed in the mud treatment system, wherein the treatment mud is configured for treating the wellbore fluids. The method includes logging the well using the logging string, and treating the wellbore fluids using the treatment mud to form treated wellbore fluids.

First claim

What is claimed is:

1 . A method comprising:
drilling a wellbore of a well in a formation using a drill string of a drilling system in hydraulic communication with the formation; deploying a logging string configured to hydraulically couple to the drilling system using the drill string and comprising a jet nozzle and an anchor to a determined depth in the wellbore; hydraulically coupling a jetting treatment system comprising a mud treatment system to a mud circulation system; hydraulically coupling a drilling mud comprising wellbore fluids to the mud circulation system; hydraulically coupling the mud circulation system to a drill string bore of the drill string; activating the mud circulation system to circulate the drilling mud in the wellbore; activating the jetting treatment system to circulate the drilling mud in the mud treatment system; circulating in the wellbore, using the jetting treatment system, a treatment mud, disposed in the mud treatment system, wherein the treatment mud is configured for treating the wellbore fluids; logging the well using the logging string; treating the wellbore fluids using the treatment mud to form treated wellbore fluids; deactivating the mud circulation system to stop circulating the drilling mud in the wellbore; deactivating the jetting treatment system to stop circulating the drilling mud in the mud treatment system; and retrieving the logging string from the wellbore.

2 . The method of claim 1 ,
wherein the jetting treatment system is configured for:
activating upon receipt of an activation signal; and
deactivating upon receipt of a deactivation signal;
wherein drilling the wellbore further comprises:
monitoring, using a mud condition sensing system, a first mud condition of the drilling mud circulated by the mud circulation system;
comparing, using a computer processor, the first mud condition with a first predetermined criterion to form a first comparison;
determining, using the computer processor, a first result of the first comparison;
transmitting, using a control system, the activation signal to the jetting treatment system, based on the first result failing to satisfy the first predetermined criterion;
activating the jetting treatment system in response to receipt of the activation signal;
monitoring, using the mud condition sensing system, a second mud condition of the drilling mud;
comparing, using the computer processor, the second mud condition with a second predetermined criterion to form a second comparison;
determining, using the computer processor, a second result of the second comparison;
transmitting, using the control system, the deactivation signal to the jetting treatment system, based on the second result satisfying the second predetermined criterion; and
deactivating the jetting treatment system in response to receipt of the deactivation signal.

3 . The method of claim 1 ,
wherein deploying the logging string comprises coupling the logging string to the wellbore; and retrieving the logging string comprises decoupling the logging string from the wellbore.

4 . The method of claim 1 ,
wherein activating the jetting treatment system comprises:
anchoring, using a jet anchor system comprising a jet-anchor, the logging string to the wellbore; and
wherein the jet-anchor comprises the jet nozzle and the anchor; wherein anchoring comprises:
extending the jet-anchor from a logging tool outer surface to form a surface-surface contact between an anchor pad disposed on the anchor and the wellbore, and
exposing the jet nozzle out from the logging tool outer surface for fluid communication from the drill string bore to the wellbore.

5 . The method of claim 1 ,
wherein treating the wellbore fluids comprises extending, using a lock mandrel and a mandrel driver, the anchor coupled to the logging string from a decoupled position to a coupled position; wherein the coupled position comprises a coupling of an anchor pad, disposed on the anchor, and the wellbore.

6 . The method of claim 1 ,
wherein activating the jetting treatment system comprises:
pressuring a substance in the drill string to a first drillpipe pressure; and
depressurizing the substance from the first drillpipe pressure to a second drillpipe pressure,
wherein deactivating the jetting treatment system comprises:
pressuring the substance from the second drillpipe pressure to a third drillpipe pressure; and
depressurizing the substance from the third drillpipe pressure to a fourth drillpipe pressure.

7 . The method of claim 1 ,
wherein activating the jetting treatment system comprises: cycling a drillpipe pressure input to an indexer coupled to the logging string; wherein cycling comprises a shifting of the indexer; wherein the shifting of the indexer comprises:
shifting from a first indexer setting to a second indexer setting in response to a first drillpipe pressure input,
shifting from the second indexer setting to a third indexer setting in response to a second drillpipe pressure input,
shifting from the third indexer setting to a fourth indexer setting in response to a third drillpipe pressure input, and
shifting from the fourth indexer setting to the first indexer setting in response to a fourth drillpipe pressure input.

8 . The method of claim 1 ,
wherein treating the wellbore fluids comprises generating a turbulent flow at the determined depth using the jetting treatment system.

9 . The method of claim 1 , further comprising:
maintaining the wellbore fluids using the treated wellbore fluids, the jetting treatment system, the mud treatment system, the mud circulation system, and the drilling mud.

10 . The method of claim 1 ,
wherein the formation comprises an openhole formation; wherein the determined depth comprises a wellbore depth to an openhole formation depth; and wherein the openhole formation comprises a high overbalanced hydrostatic pressure against a formation pressure; wherein treating the wellbore fluids further comprises;
shearing the wellbore fluids,
preventing a solids fallback, and
conditioning a filter cake.

11 . A system comprising:
a drill string of a drilling system in hydraulic communication with a formation configured for drilling a wellbore of a well in the formation; a logging string comprising a jet nozzle and an anchor configured for deploying to a determined depth in the wellbore and hydraulically couple to the drilling system using the drill string; a jetting treatment system comprising a mud treatment system configured for hydraulically coupling to a mud circulation system; a drilling mud comprising wellbore fluids configured for hydraulically coupling to the mud circulation system; wherein the mud circulation system is configured for hydraulically coupling to a drill string bore of the drill string; wherein the mud circulation system, when activated, is configured to circulate the drilling mud in the wellbore; wherein the jetting treatment system, when activated, is configured to circulate the drilling mud in the mud treatment system; and a treatment mud disposed in the mud treatment system configured for:
