The present disclosure applies to drilling operations.
In conventional drilling operations, such as drilling operations for oil wells, the borehole of the well is normally filled with kill fluid in order to provide enough hydrostatic pressure to control the penetrated formation pressures. This is done to prevent potential well control incidents. The amount of hydrostatic pressure that is generated depends on the used mud density and the height of the fluid column (
The present disclosure describes techniques that can be used for controlling, based on quantitative information, increases to the mud weight during drilling operations. In some implementations, a computer-implemented method includes the following. A tool is deployed on a bottom hole assembly (BHA) near a surface of a well being drilled. The tool is a retrievable acoustic mud level detector configured to send and receive acoustic waves during a drilling operation of the well. Acoustic waves are propagated using an acoustic wave source in the tool. The acoustic waves propagate constantly through an air medium in a wellbore of the well and partially reflect waves when meeting a fluid interface in the wellbore. A signal including a reflected wave reflected from the fluid interface is received using an acoustic wave receiver on the tool. An estimate of a fluid level depth of the fluid interface is determined using the tool to process the received signal. A kill mud weight of mud in the wellbore is increased in response to determining the estimate and using a current mud weight of mud in the wellbore.
The previously described implementation is implementable using a computer-implemented method; a non-transitory, computer-readable medium storing computer-readable instructions to perform the computer-implemented method; and a computer-implemented system including a computer memory interoperably coupled with a hardware processor configured to perform the computer-implemented method, the instructions stored on the non-transitory, computer-readable medium.
The subject matter described in this specification can be implemented in particular implementations, so as to realize one or more of the following advantages. Techniques of the present disclosure can provide a quantitative estimate of the mud level, making it possible to quantitatively and accurately adjust the required mud weight for a drilling operation. Developing this technology and methodology can minimize the frequency of well control incidents due to total losses cases. Conventional techniques typically focus on fixed detectors, in which a source and receivers are separated. A tool created using the present techniques can provide mobility, in that the availability of top and bottom connections of the tool allows for the installation and retrieval between drill pipes by the rig when needed, a feature not available using conventional techniques. The design of the present disclosure combines the source and receiver in a single, integrated tool having a vertical configuration, allowing the tool to pass through the blowout preventer (BOP) and be lowered to the casing. Knowing the location of fluid level during drilling is economically advantageous, allowing a more accurate kill mud weight adjustment. By comparison, in conventional systems, it is normal that in case of total losses where the fluid level is unknown, it is industry common practice that the kill mud weight is increased by 10 pounds per cubic feet (pcf) to account for the uncertain hydrostatic pressure drop resulting from the fluid level drop. Techniques of the present disclosure enable a more precise estimate of the current fluid level and, accordingly, an improved adjustment to the kill mud weight as needed (e.g., less than 10 pcf). Cost savings that are derived from saving the chemicals required to increase the mud weight are quantitatively proportional to the mud weight. However, the cost savings can also vary depending on the types of chemicals required to adjust the mud weight as well as the rate of losses.
The details of one or more implementations of the subject matter of this specification are set forth in the Detailed Description, the accompanying drawings, and the claims. Other features, aspects, and advantages of the subject matter will become apparent from the Detailed Description, the claims, and the accompanying drawings.
Like reference numbers and designations in the various drawings indicate like elements.
The following detailed description describes techniques for more accurate (e.g., necessary and sufficient) kill mud weight adjustments during drilling operations. Various modifications, alterations, and permutations of the disclosed implementations can be made and will be readily apparent to those of ordinary skill in the art, and the general principles defined may be applied to other implementations and applications, without departing from the scope of the disclosure. In some instances, details unnecessary to obtain an understanding of the described subject matter may be omitted so as to not obscure one or more described implementations with unnecessary detail and inasmuch as such details are within the skill of one of ordinary skill in the art. The present disclosure is not intended to be limited to the described or illustrated implementations, but to be accorded the widest scope consistent with the described principles and features.
The present disclosure describes a new tool that can be positioned with the drilling bottom hole assembly (BHA) near the surface to estimate the fluid level in the wellbore in case of total losses. The tool includes an acoustic wave source and receiver attached to a metallic pipe with a top and bottom connection, such that the acoustic wave propagates constantly through the air medium and partially reflects when it meets the fluid interface. The acoustic receiver picks up the reflected wave, and then the signal is processed to estimate the fluid level depth.
In conventional drilling operations, such as for oil wells, the borehole of the well is normally filled with kill fluid in order to provide enough hydrostatic pressure to control the penetrated formation pressures (e.g., to balance the formation pressure). This is done to prevent potential well control incidents.
The present disclosure describes techniques that can be used to resolve the issues identified with respect to
At 502, a tool is deployed on a bottom hole assembly (BHA) near a surface of a well being drilled. The tool is a retrievable acoustic mud level detector configured to send and receive acoustic waves during a drilling operation of the well. Deploying the tool can include passing the tool through a blowout preventer (BOP) and lowering the tool to a casing, for example. From 502, method 500 proceeds to 504.
At 504, acoustic waves are propagated using an acoustic wave source in the tool. The acoustic waves propagate constantly through an air medium in a wellbore of the well and partially reflect waves when meeting a fluid interface in the wellbore. The acoustic wave source and the acoustic wave receiver are integrated on the same tool, as shown in
At 506, a signal including a reflected wave reflected from the fluid interface is received using an acoustic wave receiver on the tool, e.g., as described with reference to
At 508, an estimate of a fluid level depth of the fluid interface is determined using the tool to process the received signal. For example, the estimate can be based on functions including speed=distance/time, as described with reference to
At 510, a kill mud weight of mud in the wellbore is increased in response to determining the estimate using a current mud weight of mud in the wellbore. For example, increasing the kill mud weight of the mud in the wellbore can include automatically injecting mud into the wellbore based on the estimate, e.g., using computer-implemented software at the surface of the well. After 510, method 500 can stop.
In some implementations, in addition to (or in combination with) any previously-described features, techniques of the present disclosure can include the following. Outputs of the techniques of the present disclosure can be performed before, during, or in combination with wellbore operations, such as to provide inputs to change the settings or parameters of equipment used for drilling. Examples of wellbore operations include forming/drilling a wellbore, hydraulic fracturing, and producing through the wellbore, to name a few. The wellbore operations can be triggered or controlled, for example, by outputs of the methods of the present disclosure. In some implementations, customized user interfaces can present intermediate or final results of the above described processes to a user. Information can be presented in one or more textual, tabular, or graphical formats, such as through a dashboard. The information can be presented at one or more on-site locations (such as at an oil well or other facility), on the Internet (such as on a webpage), on a mobile application (or “app”), or at a central processing facility. The presented information can include suggestions, such as suggested changes in parameters or processing inputs, that the user can select to implement improvements in a production environment, such as in the exploration, production, and/or testing of petrochemical processes or facilities. For example, the suggestions can include parameters that, when selected by the user, can cause a change to, or an improvement in, drilling parameters (including drill bit speed and direction) or overall production of a gas or oil well. The suggestions, when implemented by the user, can improve the speed and accuracy of calculations, streamline processes, improve models, and solve problems related to efficiency, performance, safety, reliability, costs, downtime, and the need for human interaction. In some implementations, the suggestions can be implemented in real-time, such as to provide an immediate or near-immediate change in operations or in a model. The term real-time can correspond, for example, to events that occur within a specified period of time, such as within one minute or within one second. Events can include readings or measurements captured by downhole equipment such as sensors, pumps, bottom hole assemblies, or other equipment. The readings or measurements can be analyzed at the surface, such as by using applications that can include modeling applications and machine learning. The analysis can be used to generate changes to settings of downhole equipment, such as drilling equipment. In some implementations, values of parameters or other variables that are determined can be used automatically (such as through using rules) to implement changes in oil or gas well exploration, production/drilling, or testing. For example, outputs of the present disclosure can be used as inputs to other equipment and/or systems at a facility. This can be especially useful for systems or various pieces of equipment that are located several meters or several miles apart, or are located in different countries or other jurisdictions.

Locking or consistency tracking may not be necessary since the locking of exchange file system can be done at the application layer. Furthermore, Unicode data files can be different from non-Unicode data files.
While this specification contains many specific implementation details, these should not be construed as limitations on the scope of what may be claimed, but rather as descriptions of features that may be specific to particular implementations. Certain features that are described in this specification in the context of separate implementations can also be implemented, in combination, in a single implementation. Conversely, various features that are described in the context of a single implementation can also be implemented in multiple implementations, separately, or in any suitable sub-combination. Moreover, although previously described features may be described as acting in certain combinations and even initially claimed as such, one or more features from a claimed combination can, in some cases, be excised from the combination, and the claimed combination may be directed to a sub-combination or variation of a sub-combination.
Particular implementations of the subject matter have been described. Other implementations, alterations, and permutations of the described implementations are within the scope of the following claims as will be apparent to those skilled in the art. While operations are depicted in the drawings or claims in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed (some operations may be considered optional), to achieve desirable results. In certain circumstances, multitasking or parallel processing (or a combination of multitasking and parallel processing) may be advantageous and performed as deemed appropriate.
Moreover, the separation or integration of various system modules and components in the previously described implementations should not be understood as requiring such separation or integration in all implementations. It should be understood that the described program components and systems can generally be integrated together in a single software product or packaged into multiple software products.
Accordingly, the previously described example implementations do not define or constrain the present disclosure. Other changes, substitutions, and alterations are also possible without departing from the spirit and scope of the present disclosure.
