... multilateral candidate had a six 6 1/8-in. uncased horizontal sections that needed cleanout from drilling oil-based mud (OBM) and matrix stimulation using an emulsified retarded acid system (ERAS) for enhanced wormholing into the carbonate rock. The lateral sections exhibited an average of 2,500 ft...

... heterogenous reservoir. Torque and drag simulations are critical to determine if the AICV completion string with inner string has sufficient weight to navigate through complex well geometry (horizontal section with azimuthal change) to land the string at TD. A flow activated turbine reamer is installed...

... and fewer microseismic events, which affects the interpretation validity and limits its application. Downhole horizontal array monitoring (DHAM) (i.e., deploying the geophone array in the horizontal section of an offset well ( Fig. 1, 1b ), is an alternative. For acquisition, the three-component...

... horizontal section along with the requirement to spot a 2,100 ft continuous cement plug on top of the BHA to abandon the well. The main challenge for setting a cement plug across a horizontal section, is cement slumping and stuck pipe, which might result in repeating cement plug jobs or non-productive time...

... in the Limestone-K1 formation (2.4- to 2.8-g/cm3 bulk density), which is highly fractured with multiple faults crossing the horizontal section. This condition generates high microDLS, which increases tortuosity and torque on the drillstring, as well as stress, shock, and vibration on the tools, all of which limit...

... and the likelihood of gas kick, as well drilling through fractures on the horizontal section and experiencing potential total fluid losses, made successfully drilling the wells to TD even more difficult and challenging. The buildup section was divided into two string designs based on a previously used single-string...
