A drill pipe string conveyed bridge plug running tool (100) and a method for forming and verifying a cement plug
Introduction
The present invention relates to a running tool for a mechanical bridge plug in a petroleum well.
More specifically, it relates to a running tool also arranged for working as a cementing tool, while further also arranged for working as a dressing and tagging tool.
A petroleum well section may be cement plugged in the casing at a given depth for several reasons.
The plug may be formed either for permanent plug and abandon (PPA), temporary plug and abandoning (TPA) or for drilling a sidetrack or removing and replacing or otherwise remedying the casing above the plug. The cement plugging process is usually conducted by the following steps: - Run in, into the cased well, a bridge plug conveyed on a J-slot tool at the lower end of a wireline or drill pipe string. - Set the bridge plug in the casing, either by mechanical manipulation or hydraulic setting.
The bridge plug is now set in the casing to form a basis for forming a later circulated in cement plug. - LH rotating the drill pipe string while slacking off / weight loading the J-slot running tool in order to disconnecting the J-slot running tool from a corresponding J-slot stinger at the top of the bridge plug, - POOH the J-slot running tool, - RIH a cementing stinger to bridge plug and PU while cementing entire length of cement plug, i.e. 50m. - POOH cementing stinger. - RIH a DP conveyed dress and tag tool and dress away low quality upper part of cement plug until expected proper quality hardened cement is exposed to the dress and tag tool, - Weight load the tag tool to tag the top of the cement plug exposed, to verify the cement plug.
It is possible, but not desirable from a cement plug quality point of view, to shorten the above sequence by replacing, after disconnecting the J-slot running tool from the J-slot stinger, by circulating in the cement through the J-slot running tool" connector sleeve and imperfectly dress and tag, if at all possible, the so formed cement plug. However, a J-slot connector sleeve has a rather
; DK 2023 70225 A1 broad inner Ø and large outer Ø and is poorly designed for cementing, and would dress and tag the cement plug only peripherally thus imperfectly.
A petroleum oil tool provider usually has a repository of drill pipe conveyed J-slot running tools adapted for being connected to a J-slot stinger on top of a wide variety of diameters and types of casing plugs. The plugs may be of various types such as - removable bridge plugs (RBP), - temporary DP string hang-off plugs, - pressure test plugs, and —-permanent bridge plugs such as for forming a cementing base.
It is desirable to have a common J-slot stinger interface on top of most or all of such casing plugs in order to keep the logistics' number of tools low, both to reduce required on-board storage space on the drilling or intervention platform, and offshore or land transport costs.
US2019/0390527A1 Telfer, Ardyne Holdings Ltd, UK, "Improvements in or relating to well abandonment and slot recovery", describes a method and apparatus for single-trip cementing and casing cutting for well abandonment and slot recovery. Using a tool string including a casing cutter and a stinger, where the casing cutter has a central through bore including a wall to isolate the cutting assembly from the cement, cement can be passed through the cuter and deposited using the stinger to form a plug. The method preferably includes the additional steps of incuding a bridge plug on the tool string and setting the bridge plug in the well before passing fluidised plugging material through the stinger to deposit a quantity of fluidised plugging material into the well bore to form a cement plug.
NO20151699A1 Sørhus, Archer Oiltools AS, NO, "Drill pipe string conveyed pressure integrity test tool and method for testing the pressure integrity of a casing", describes a method of testing the pressure integrity of a casing, comprising: - providing a drill pipe string conveyed pressure integrity tool section for a casing, comprising: - a cylindrical tool stem having an axial bore and upper and lower tool joints to said drill pipe string and a drilling or milling bit; - a relative downward annulus flow closing check valve comprising a check valve body on said tool stem, - running said testing tool section to a target depth in the casing with the check valve open, - halting the test tool section at target depth, - increasing pressure in the casing bore to displace the check valve to its lower, closing position, - verifying integrity of the casing above the swab cup.
2 DK 2023 70225 A1
The present invention provides a solution to the problems which may arise when one wants to take into account this overall goal of having a common stinger interface on top of the variety of plugs on board the drilling or intervention platform.
