DETAILED DESCRIPTION OF THE EMBODIMENTS
[00017] Before explaining the present computer readable medium in detail, it is to be understood that the computer readable medium is not limited to the particular embodiments and that it can be practiced or carried out in various ways.
[00018] The present embodiments generally relate to a computer readable medium for capturing surface data and calculating calibrated data in real time to a user via an executive dashboard of surface logs during the drilling of a well, during work over of a well, after drilling a well, and combinations thereof.
[00019] The computer readable medium can enable detection of high range component peaks and low range component peaks of entrained gas in a drilling fluid continuously and pushes the detected data to client devices for immediate action and for governmental environmental protection reporting purposes, and to ensure regulation compliance by a drilling operator.
[00020] The computer readable medium can create an executive dashboard that enables a geologist to see great detail in the component gases of the drilling fluid, and greater detail and accuracy of data acquisition, at point of data capture.
[00021] The computer readable medium can create an executive dashboard that provides highly accurate and high integrity data because the computer readable medium can capture data quickly.
[00022] The term "quickly" as used herein can refer to a sampling density over an interval of time. The computer readable medium can allow a high volume of sampling. The computer readable medium in an embodiment, can sample 16 data points per second thereby providing a high density sampling with high integrity with great detail. In an embodiment, the computer readable medium can sample 4 data points per second for a low density sampling which also occurs "quickly" and which may be desirable when data storage capacity is a concern.
[00023] The term "real time" can refers to data which is transmitted at the moment the data is detected by a sensor or detector or at the moment the analysis of a fluid sample is complete.
[00024] The computer readable medium can be used with multiple gas detection instruments simultaneously, wherein each gas detection instruction is based on different gas detection theories. The computer readable medium can control and run many gas detection instruments simultaneously.
[00025] The computer readable medium can be used with multiple gas detection instruments simultaneously, for bidirectional data exchange with local and remote rig servers. In embodiments, each device can have different well site information and different transfer specification standards.
[00026] The multiple gas detection instruments, such as SLIC-841 and SLIC-9 gas detection instruments made by Selman and Associates, Ltd. of Midland, Texas, are both based on Catalytic Combustion and Thermal Conductivity gas detection theories (both theories on both instruments). Each instrument has a total hydrocarbons detector for detecting the total amount of hydrocarbons (measured in percent (%) Equivalent Methane in Air (EMA) or Units) and a gas chromatograph for speciating and measuring the various hydrocarbon components in the gas stream. The gas chromatograph results are measured in units or ppm.
[00027] The computer readable medium can also connect with a helium detector in a continuously and simultaneously manner.
[00028] The computer readable medium can also connect with rig detectors, such as hook load sensors, pump pressure sensors, pump stroke counters, depth sensors, providing all detail simultaneously, providing a highly accurate total view of the rig, the drilling fluid, and the related geology of the drilling.
[00029] This computer readable medium can enable various detection instruments to talk to a single source.
[00030] The computer readable medium can enable continuous gas analysis while one sensor or one detector is turned off or added, and brought online. In an embodiment, the computer readable medium can allow for comingled sensor and protocol data.
1000311 The computer readable medium can allow a user to monitor a single sensor in a fluid analysis instrument or to a single or multiple sensors placed on a rig, simultaneously.
[00032] The computer readable medium can allow WITS analysis to occur while individual sensor analysis occurs.
[00033] The computer readable medium can create an easy to use, graphical executive dashboard.
[00034] The computer readable medium can allow high accuracy sampling with menu driven calibration for the gas detectors. The data of this computer readable medium can be accurate to +1- 1%.
[00035] The computer readable medium can allow 16 bit results. The accuracy depends on the magnitude of the value. The computer readable medium can allow for at least different results with an accuracy that is down to sub parts per million levels, such as an accuracy of 0.5 parts per million.
[00036] The computer readable medium can allow precise intervals of measurement for chromatographs attached to the computer readable medium, in the parts per million (ppm) range or a percent equivalent methane in air (EMA) in an easy to view environment, such as a WINDOWS environment for higher accuracy of measurement by allowing detection of high range and low ranges, simultaneously.
[00037] For example, the computer readable medium can allow a user to measure high range and low range signals for the gas chromatograph simultaneously for highly accurate results providing detailed real time well logs while drilling.
[00038] Additionally, the computer readable medium can perform calibration of a total hydrocarbon detector and a gas chromatograph without shutting down other detectors that may be supplying information.
[00039] The computer readable medium can perform calibration of one or more of the analyzers, without human intervention, such as calibrating the total hydrocarbon detector while the gas chromatograph is operating, and analyzing and providing information to a gas processor.
[00040] The computer readable medium can produce data to populate a geological-hydrocarbon log, such as a well surface log by real time streaming of detected and analyzed data from drilling operations.
[00041] The computer readable medium can operate at the drilling location, at a remote location, or both. As such, the computer readable medium can allow for simultaneous localized calibration, monitoring and analysis and remote calibration, monitoring and analysis.
[00042] The localized monitoring and remote monitoring can be performed over a network using at least one client device, such as a laptop, cellular or mobile phone, a smart phone, a tablet, a netbook, the like, a desktop computer, or other networkable device capable of data processing and data storage.
[00043] The data is acquired and stored in a database in the gas processor data storage.
[00044] The gas processor uses computer instructions of the computer readable medium to both create an executive dashboard and then populate the executive dashboard using the data in the database and as the data is streamed live from actual rig or fluid detectors or as the gas is analyzed, such as from a gas chromatograph and a total hydrocarbon detector.
[00045] The gas processor uses computer instructions of the computer readable medium to transmit the populated executive dashboard over a network to various client devices.
[00046] The network can be a fiber optic network, a wired network, such as a Cat5e network, the Internet, a wireless local area network (WLAN), such as WIFITM, other wireless networks, other wired networks, a satellite network, a cellular network, other communication networks, or combinations thereof.
