The present disclosure generally relates to downhole monitoring.
Completion systems for oil and gas wells can include various sensors, gauges, and mandrels. In various applications, it may be desirable to monitor tubing pressure or annulus pressure.
In some configurations, a tubing to annulus converting olive includes one or more radially extending ports disposed about a circumference of the olive.
The olive can further include an axial port extending from an axial end of the olive into a body of the olive. The axial port does not extend through an entire axial length of the olive. The axial port intersects and is in fluid communication with the one or more radially extending ports. The olive can be metal. The olive can be sized and shaped to be disposed in a tubing pressure port of a gauge mandrel.
In some configurations, a monitoring system includes a gauge comprising a sensor and housed on a mandrel. The mandrel includes a pressure test port and a tubing pressure port configured to direct tubing pressure to the sensor. The system also includes a tubing to annulus converting olive disposed in the tubing pressure port and configured to block the tubing pressure port and allow annulus pressure to reach the sensor via a flow path through the pressure test port and the olive.
The mandrel can define a central longitudinal bore. The tubing pressure port extends radially through a wall of the mandrel from the central longitudinal bore. The tubing pressure port places the central longitudinal bore in fluid communication with the sensor of the gauge. The pressure test port places an annulus outside the mandrel in fluid communication with the sensor of the gauge.
The olive includes an axial port extending from an axial end of the olive partially through a body of the olive; and one or more radially extending ports disposed about a circumference of the olive, wherein the one or more radially extending ports are in fluid communication with the axial port. The olive is oriented such that the axial port is in fluid communication with the sensor of the gauge, and the olive blocks fluid communication between a central longitudinal bore of the mandrel and the sensor of the gauge.
In some configurations, a method of monitoring pressure in a wellbore includes determining whether to monitor tubing pressure or annulus pressure; and if monitoring annulus pressure, disposing a tubing to annulus converting olive in a tubing pressure port of a gauge mandrel. The method can further include monitoring annulus pressure via a flow path through a pressure test port of the gauge mandrel and through the tubing to annulus converting olive to a sensor of the gauge mandrel.
Certain embodiments, features, aspects, and advantages of the disclosure will hereafter be described with reference to the accompanying drawings, wherein like reference numerals denote like elements. It should be understood that the accompanying figures illustrate the various implementations described herein and are not meant to limit the scope of various technologies described herein.
In the following description, numerous details are set forth to provide an understanding of some embodiments of the present disclosure. It is to be understood that the following disclosure provides many different embodiments, or examples, for implementing different features of various embodiments. Specific examples of components and arrangements are described below to simplify the disclosure. These are, of course, merely examples and are not intended to be limiting. However, it will be understood by those of ordinary skill in the art that the system and/or methodology may be practiced without these details and that numerous variations or modifications from the described embodiments are possible. This description is not to be taken in a limiting sense, but rather made merely for the purpose of describing general principles of the implementations. The scope of the described implementations should be ascertained with reference to the issued claims.
As used herein, the terms “connect”, “connection”, “connected”, “in connection with”, and “connecting” are used to mean “in direct connection with” or “in connection with via one or more elements”; and the term “set” is used to mean “one element” or “more than one element”. Further, the terms “couple”, “coupling”, “coupled”, “coupled together”, and “coupled with” are used to mean “directly coupled together” or “coupled together via one or more elements”. As used herein, the terms “up” and “down”; “upper” and “lower”; “top” and “bottom”; and other like terms indicating relative positions to a given point or element are utilized to more clearly describe some elements. Commonly, these terms relate to a reference point at the surface from which drilling operations are initiated as being the top point and the total depth being the lowest point, wherein the well (e.g., wellbore, borehole) is vertical, horizontal or slanted relative to the surface.
Completion systems for oil and gas wells can include various sensors, gauges, and mandrels. In some cases, it may not be known in advance if it will be desirable to read tubing or annulus pressure. It can therefore be necessary to have two different types of gauges and mandrels on hand, and too many variants becomes a challenge to FMT in or out and increases inventory on hand. The present application provides devices, systems, and methods including a tubing to annulus converting olive (or TACO). The tubing to annulus converting olive advantageously enables a completion including a tubing-reading gauge and a SGM (solid gauge mandrel) to read the tubing or the annulus pressure.
Language of degree used herein, such as the terms “approximately,” “about,” “generally,” and “substantially” as used herein represent a value, amount, or characteristic close to the stated value, amount, or characteristic that still performs a desired function or achieves a desired result. For example, the terms “approximately,” “about,” “generally,” and “substantially” may refer to an amount that is within less than 10% of, within less than 5% of, within less than 1% of, within less than 0.1% of, and/or within less than 0.01% of the stated amount. As another example, in certain embodiments, the terms “generally parallel” and “substantially parallel” or “generally perpendicular” and “substantially perpendicular” refer to a value, amount, or characteristic that departs from exactly parallel or perpendicular, respectively, by less than or equal to 15 degrees, 10 degrees, 5 degrees, 3 degrees, 1 degree, or 0.1 degree.
Although a few embodiments of the disclosure have been described in detail above, those of ordinary skill in the art will readily appreciate that many modifications are possible without materially departing from the teachings of this disclosure. Accordingly, such modifications are intended to be included within the scope of this disclosure as defined in the claims. It is also contemplated that various combinations or sub-combinations of the specific features and aspects of the embodiments described may be made and still fall within the scope of the disclosure. It should be understood that various features and aspects of the disclosed embodiments can be combined with, or substituted for, one another in order to form varying modes of the embodiments of the disclosure. Thus, it is intended that the scope of the disclosure herein should not be limited by the particular embodiments described above.
The present application claims priority benefit of U.S. Provisional Application No. 63/272,894, filed Oct. 28, 2021, the entirety of which is incorporated by reference herein and should be considered part of this specification.
