The paper has not been peer reviewed. Pressurized-mud-cap drilling (PMCD) and early kick detection (EKD) are two unconventional drilling techniques that have been used widely individually, mostly in relation to closed and pressurizable systems and to managed-pressure-drilling (MPD) applications. The techniques, however, are seldom used together as an integrated setup. This paper describes a synergized PMCD and EKD setup and the field deployment where it was used to drill a well successfully offshore Kalimantan, Indonesia, that had a high-pressure formation below a zone prone to severe circulation losses. Introduction Many drilling problems offshore Kalimantan involve lost-circulation problems and unintended influxes. Drilling conventionally through fractured and extremely vugular carbonate formations, which are prone to severe lost-circulation problems, can lead eventually to well-control situations. Aside from that, significant time and resources are required to cure the losses before conventional drilling can be continued. In addition, of 1,000 ft of carbonate formation drilled offshore Kalimantan, the fractures often are present in layers, which will multiply considerably the time and resources spent each time severe or total loss is encountered. One of the more well-known ways to mitigate this problem is implementation of the variant of MPD called PMCD, which enables the operator to drill through the fractured formation safely and efficiently. Meanwhile, also in offshore Kalimantan, most of the zone that resides just several feet below the fractured carbonate formation is highly pressurized gas reservoir. Drilling conventionally through such a pressurized zone exposes the operation to greater risk because of a lack of precision in detecting any influx or outflux during the drilling operation. A better method for detecting influx is the use of a flowmeter to monitor the flow from the well. The most common flowmeter used is a Coriolis mass flowmeter (CMF). Although the CMF has the advantage of great precision in measuring flow rates, the conventional setup lacks accuracy because the system is open to the atmosphere. A further improvement is to use it in conjunction with the MPD system to create a closed-loop system that will increase accuracy. This is the EKD system.
