Systems and methods for inferring reservoir pressure based on initial coiled tubing run conditions

A processing and control system, comprising:

• one or more processors configured to execute processor-executable instructions stored in memory media of the processing and control system, wherein the processor-executable instructions, when executed by the one or more processors, cause the processing and control system to:
• receive data relating to one or more operating parameters of a coiled tubing operation performed by via a coiled tubing system at least partially disposed within a wellbore, wherein the data is detected by one or more sensors of a coiled tubing system during the coiled tubing operation;
• determine an initial wellbore fluid distribution in the wellbore based at least in part on the data relating to the one or more operating parameters of the coiled tubing operation prior to pumping fluid into the wellbore from a surface location relative to the wellbore;
• and
• infer a reservoir pressure of a hydrocarbon-bearing reservoir through which the wellbore extends based at least in part on the initial wellbore fluid distribution in the wellbore.

A method, comprising:

• performing a coiled tubing operation via a coiled tubing system at least partially disposed within a wellbore;
• detecting data relating to one or more operating parameters of the coiled tubing operation via one or more sensors of the coiled tubing system during the coiled tubing operation;
• determining an average density of a fluid mixture in the wellbore between a bottom hole assembly (BHA) of the coiled tubing system and a downhole pressure gauge based at least in part on the detected data prior to pumping fluid into the wellbore from a surface location relative to the wellbore;
• and
• inferring a reservoir pressure of a hydrocarbon-bearing reservoir through which the wellbore extends based at least in part on the average density of the fluid mixture in the wellbore between the BHA of the coiled tubing system and the downhole pressure gauge.
