Computational Fluid Dynamics (CFD) to create a 3D model simulating the effects of fluid intermixing and flow, plus the final position of total fluids to understand and minimize risks presented in multi-stage and liner cementing jobs. ECD is traditional primary area of focus measuring the impact of friction...

.... Utilization of completion strings was defined as the common performance envelope area defined by intersections of The Von Mises's Ellipse API Technical Report 5C3 Connection capacities The upper end of the lower completion that hangs off in the parent wellbore is usually a liner hanger...

... a hydrocarbon gradient. In both scenarios, the external pressure profile assumes the original hydrostatic column of mud used to land the casing as a worst-case scenario for collapse. The consequence of a loss of liner hanger system integrity for an unforeseen reason was also assessed. In wells where...

... Abstract Cementing conventional production liners is a mature topic with documented success. For wells drilled in a shallow domain, such as 4,000 feet or less, there can be challenges routinely overlooked technically as well as operationally. If not accounting for these challenges during...

... and / or 4 mm nozzles. Consequently, these 6 to 8 mm nozzles ICDs were replaced by 4 mm DPNA LEL joints with equivalent flow area per the ICD designs. The liner operation went successfully saving the Company in ICD cost as well as the rig time with washpipe-less fluid displacement provided by the combination...

... Abstract A shaped charge for wellbore perforation includes a solid metal or powder liner pressed onto a case, sandwiching high explosives which may have varying thermal stability, dictated by the expected time of exposure and bottom hole temperature (BHT). It is common knowledge that post...

... initiation sleeve is a tool installed in the toe of a completion liner and is used to establish a flowpath to the reservoir without the use of intervention. Conventional toe initiation sleeves require either intervention or increasing pressure to higher than the liner test pressure to activate. These methods...

.... A primary cement operation of a 10 1/8" production liner (within a 12 ¼" drilled hole section) was challenging due to a combination of high equivalent circulation density (ECD) and potential losses across a layered GOM reservoir. One layer had potential and significant depletion up to 8,000 psi. Critical...

...) of the liner at Total Depth (TD) to improve Equivalent Circulating Density (ECD) of the next cementing operation. A bigger ID also gives room for higher production rates due to lower pressure through prod tubing. As operators are looking to cut well costs, well designs are optimized with as few casing strings...

The team selected innovative and low cost techniques to overcome many challenges, from high DLS in unconsolidated formations using simple mud motor BHA, to running 4-1/2" liner up to 115deg inclination and implementing a thixotropic mixed metal oxide mud system to mitigate losses...

...Introduction Slotted liners are widely used to improve the performance of horizontal wells. They are mainly used for sandstone (Ref. 1), and limestone reservoirs. There are also applications in shale reservoir. However, the openings on the casing/liner can reduce the strength under geotectonic...
