Abstract
A single well development system has a base structure (8) through which the well is drilled and completed by means of a wellhead (6). A retrievable Christmas tree module (10) containing a Christmas tree (12) connected to wellhead connector (14) is mounted on the base structure (8) by the wellhead connector (14) so as to receive well fluid from the wellhead. The module (10) contains two fluid processing separators (16) for processing fluid received from the well via the wellhead (6) and the Christmas tree (12). In a modification, additional modules are mounted on the base structure and each additional module has a fluid processing separator (16), and the Christmas tree module routes production fluid to the separators via the base structure (8).
Description
- The present invention relates to the economically viable extraction of hydrocarbon reserves from a single sub-sea well.
- Existing single well-developments are generally connected to a host facility which is often located remotely from the well, where processing equipment is situated. In situations in which the well has insufficient drive or pressure, pressure boosting of production fluid by means of a pump is required. The flow may suffer from one of a number of flow assurance problems such as: (i) slug flow (flow containing slugs of gas and/or liquid); (ii) the formation of hydrates; (iii) corrosion; and (iv) sand precipitation. The provision of separate structures for treating the flow from a single well and the consequent requirement for interconnections between the wellhead and the structures may not be economically viable when only a single well is concerned.
- The object of the invention is to overcome at least some of the above-mentioned problems and provide a means by which a single subsea well field can be economically developed.
- Thus according to the invention there is provided a single well development system comprising:
- (i) a base structure through which the well is drilled and completed by means of a wellhead;
- (ii) a retrievable christmas tree module including a christmas tree and connecting means for connecting the christmas tree module to the wellhead so as to receive well fluid therefrom; and
- (iii) fluid processing means for processing fluid received from the well via the wellhead and christmas tree and which is connected closely above the base structure.
- The christmas tree module is primarily supported by means of its connection to the wellhead. The base structure and/or the christmas tree module may include supplementary support means for the christmas tree module which is independent of the wellhead connecting means.
- The system may include at least one additional retrievable module. At least one said module may include at least part of the fluid processing means.
- The fluid processing means may accordingly form part of the christmas tree module and/or one or more of the additional retrievable modules.
- Conveniently the system includes at least one fluid connector, the or each fluid connector comprising first and second engageable portions, the first portion forming part of one said retrievable module and the second portion forming part of the base structure. The engageable portions may each include plural passageways for separate fluid flows and may form part of the connecting means for connecting the christmas tree to the wellhead.
- The retrievable christmas tree module may include a power and/or control pod. At least one said retrievable module may include a power and/or control pod in which case such a pod may not form part of the christmas tree module.
- Preferably, the system includes at least one electrical connector, the or each electrical connector comprising first and second interengageable portions, the first interengageable portion forming part of said retrievable module and the second interengageable portion forming part of the base structure. The first interengageable portion is connected to the power and/or control pod in the appropriate module.
- The base structure may comprise a drilling template for drilling a well.
- The base structure may include means for guiding the at least one retrievable module onto the base structure. In addition, the base structure may have means for supporting the at least one retrievable module. The system may include a plurality of additional retrievable modules, each of which is connectable to the retrievable module containing the christmas tree via connection means, whereby the module connection means is configured to enable at least one additional retrievable module to be isolated and removed from the base structure without affecting the connection between the christmas tree module and any of the remaining modules of the system. Each module may include a module based part of the module connection means and the base structure includes a complementary base structure based part of the module connecting means.
- The connection means preferably includes fluid connectors as described above for each module. The base structure may include fluid delivery means, such as pipes, for conveying fluid flowing from the christmas tree module to the base structure in separate and/or parallel flows to the plural additional modules. The flow of fluid to each such additional module being via the corresponding fluid connector enables the additional module to be isolated from the flow.
- The base structure based second engageable portion of the fluid connectors may be connected to a flow line connection for conveying fluid from the base structure to one or more external flow lines.
- The connection means preferably also includes electrical connectors as described above. The base structure may include electrical connection means for conveying electrical power and/or control signals from one or more additional modules to the wellhead tree module. The base structure second interengageable portions of the electrical connectors may be connected to an integrated service umbilical for receipt by the system of electrical-power and/or control signals, injection chemicals for addition to fluids acted on by the system etc.
- Fluid processing means in one or more of the modules may comprise one or more separators, such a gravity separators, hydrocyclones etc. The flows through which may be controlled by means of flow control valves, preferably electrically actuated which may be adjusted under control of a power and/or control pod. A power and/or control pod in one module may be connected to control components in another module.
- The invention also provides a method of exploiting the output from a single well, comprising:
- (i) installing a base structure;
- (ii) drilling a well through the base structure;
- (iii) installing a casing string in the drilled well;
- (iv) terminating the casing string with a wellhead;
- (v) connecting a retrievable christmas tree module containing a christmas tree to the wellhead by means of connecting means so as to receive well fluid therefrom;
