SBOP Drilling Enables Efficient Drilling in Extreme Water Depths

Offshore Technology Conference, 2009
Abstract Since 1995, drilling with a surface BOP (SBOP) from a MODU has been executed successfully by operators in various offshore locations around the world. With the increasing interest in ultra-deepwater exploration, and the tight floating rig market, the SBOP high pressure riser when deployed from an upgraded ...

A Step Change in Drilling Efficiency Using Remote Operations

, 2020
Rotary steerable drilling systems are highly automated with inclination and azimuthal hold modes. These systems require only sparse communication downlinks to hold to a well plan or to compensate for geological "drift". Mud pulse transmission is one of

Controlling efficiency of laser drilling

2014 9th International Microsystems, Packaging, Assembly and Circuits Technology Conference (IMPACT), 2014
This study theoretically identifies the conditions for the keyhole collapse during drilling with a high intensity laser beam. Laser drilling is widely used in components, packaging and manufacturing technologies [1,2]. The approach adapted is to probe the quasi-steady, one-dimensional supersonic flow behavior of the two-phase, vapor-liquid dispersion ...

Successful PMCD Application Significantly Improved Drilling Efficiency on Carbonate Drilling

IADC/SPE Asia Pacific Drilling Technology Conference, 2016
Abstract Two offset wells were drilled in a field in East Malaysia, the original well and a sidetrack from the original well. Both wells experienced total lost circulation and Pressurized Mud Cap Drilling (PMCD) was attempted, but was not successful.
