... Abstract Hydraulic tree connectors can be vulnerable to hydraulic failures. This paper describes a newly developed tree connector mechanical running tool (TCMRT) that is designed to mechanically perform locking and/or unlocking of a hydraulic tree connector to the wellhead to significantly...

... not impact the oil production. Differences in observed performance were primarily related to separate water at the surface facilities. The simulator attempted to impose the BHP values accordingly. When the boundary conditions were set at the wellhead, the effects of different surface facility layouts...

... of a deepwater project. This project used the Dril-Quip 20,000 (20k) psi rated BB IIe subsea wellhead system with DXe mandrel profile and gasket, and a Badger casing connector. This paper describes the fatigue assessment and fatigue resistance design of the 20k rated BB IIe wellhead system and the fatigue...

... such as methanol injection from the wellhead. However, given that methanol could not reach the depth at which the blockage(s) were formed, a Hydrate Remediation Skid (HRS) was hired from the relevant contractors, adequate system isolations were made and depressurization carried out which eventually removed...

... Abstract We present a semi-analytical method to analyze the multi-string mechanical response of the tubulars, the wellhead and the mudline hangers (MLH) in offshore wells with a mudline suspension system (MLS). The MLS introduces redundancies at the MLH shoulders. In our method, the tubulars...

... Abstract Subsea wellhead stability is an important technical issue in deepwater and ultra-deepwater oil and gas drilling operations. Since the soil under mudline is mainly silt and clay with weak cementation, the vertical friction force and horizontal displacement provided by the surface...

... Abstract With the offshore drilling industry desiring ever increasing structural performance, this inherently suggests a move to larger wellhead mandrels. The Wellhead System presented in this paper provides an alternative approach. This program optimized existing wellhead solutions, maximized...

... Abstract On conventional vertical trees (VXTs) with a tubing hanger (TH) in the wellhead (WH), orientation of the VXT to the TH system is a complicated and expensive process. Leveraging patented technology, the tree to hanger orientation ring (THOR) and tooling were implemented to save CAPEX...

... Abstract Subsea wellhead systems have a design fatigue life that is expected to withstand the damage incurred from stress caused by cyclic loading during its operation. Wellhead fatigue is a critical factor when drilling offshore wells because the condition of the wellhead determines the length...

.... It uses a nitrogen gas spring to reverse the flex joint bending moment. The generated opposing moment increases with an increasing angle of the lower flex joint. This significantly reduces the cyclic bending moments in the lower part of the Blow Out Preventer (BOP) and wellhead (WH) system. WAMS...

For deployment to onshore unconventional fields the multiphase compressor has been packaged within a system so...

.... These challenges included wellhead interfaces capable of handling the stack-up tolerances of casing hangers, and a need to orient the tubing hanger relative to a flowline connection system. The solution utilized by most conventional systems was the incorporation of a tubing head spool or some other elaborate means...

..., single trip (MOST) tool system. Along with recovering the subsea wellhead, the associated casing strings and conductor were to be cut and retrieved. The standard MOST tool is a field-proven system, which latches externally to the wellhead, then cuts and recovers subsea wellheads. The newly released...

... Intervention Systems (Light Interventions) This type has a surface BOP (Coil tubing and/or wireline) with a subsea well control package (WCP) on top of the tree/wellhead connected via a riser. WCP consists of an Emergency Disconnect Package (EDP) and a Lower Riser Package (LRP). The EDP/LRP is a system...
