Adaptor Tool for Rotating Control Device Shooting Nipple Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of installing and removing a shooting nipple on a rotating control device of a wellhead is time and labor intensive, especially when dealing with stuck drill strings or cement bond log operations, requiring the removal and reinstallation of the rotating control device and often necessitating increased mud weight, which is costly and time-consuming.
Innovation Solution
A wellhead adaptor tool with a body, first and second flanges, and a clamp is used to couple the shooting nipple to the rotating control device, allowing for the shooting nipple to be installed without removing the rotating control device, maintaining pressure control and reducing the need for mud weight adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rotating control device is removed and a shooting nipple is installed on the wellhead, then the shooting nipple can guide the fishing assembly or cement bond log tool into the wellbore, but the process is time and labor intensive and requires increasing mud weight to maintain pressure control
Solution Approach 1:
The adaptor tool is positioned inside the rotating control device, with the shooting nipple installed on the adaptor tool. This nested configuration allows the shooting nipple to be functional while the rotating control device remains in place, eliminating the need for removal and reinstallation.
Solution Approach 2:
The adaptor tool serves as an intermediary component between the rotating control device and the shooting nipple. It provides a transition interface that allows the shooting nipple to connect to the rotating control device's internal bore, enabling wellbore operations without removing the pressure control device.
2Adaptability or versatility
If the rotating control device is removed from the wellhead, then the shooting nipple can be installed to perform wellbore operations, but increasing mud weight to hold pressurized fluids and gases becomes necessary, which is expensive and time intensive
Solution Approach 1:
The adaptor tool is positioned inside the rotating control device, with the shooting nipple installed on the adaptor tool. This nested configuration allows the shooting nipple to be functional while the rotating control device remains in place, eliminating the need for removal and reinstallation.
Solution Approach 2:
The adaptor tool serves as an intermediary component between the rotating control device and the shooting nipple. It provides a transition interface that allows the shooting nipple to connect to the rotating control device's internal bore, enabling wellbore operations without removing the pressure control device.
3Productivity
If the rotating control device is removed and reinstalled after fishing operations or cement bond log operations, then the operations can be completed, but the process is time and labor intensive
Solution Approach 1:
The adaptor tool is positioned inside the rotating control device, with the shooting nipple installed on the adaptor tool. This nested configuration allows the shooting nipple to be functional while the rotating control device remains in place, eliminating the need for removal and reinstallation.
Solution Approach 2:
The adaptor tool serves as an intermediary component between the rotating control device and the shooting nipple. It provides a transition interface that allows the shooting nipple to connect to the rotating control device's internal bore, enabling wellbore operations without removing the pressure control device.

AI summary
A wellhead adaptor tool, a system, and a method for installing a shooting nipple on a rotating control device of a wellhead. The wellhead adaptor tool has a body, a first flange, and a second flange. The body has a void. The first flange is coupled to a first portion of the body. The first flange has multiple voids to couple the body to a shooting nipple by multiple fasteners. The second flange is coupled to a second portion of the body. The second flange couples the body to a rotating control device of a wellhead coupled to a wellbore. A clamp is coupled to the second flange to couple the second flange to the rotating control device.
