The Mud logging Engineer represents contractor logging systems at the well site. He is responsible for maintaining and correctly operating the equipment supplied to provide the service. He collates and presents the information monitored per company standard procedures and customer requirements to ensure a high-quality service. To accomplish his job description, the mud logger should have a …
Background gas enters the mud circulating system as the formation is drilled by the drilling bit and usually maintains a steady but low level. Additionally, as shales are circulated up the hole, the reduction in pressure explodes the shale particles releasing gas into the drilling mud. These are the most common sources of gas. Pressure …
In this article, we will highlight the basic equipment and techniques that are used at the well site by the mud logging unit to provide the basic surface logging services. Formation Evaluation Log The surface mud logging unit is not complex in principle, does not interfere with the drilling process, and the results are available …
Hydrocarbon Gas Chromatography Analysis In Oil & Gas article is one of 5 important articles about Mud logging unit equipment. These articles explain in detail the equipment used in standard mud logging units. A chromatograph separates and analyzes hydrocarbons in the ditch gas sample to determine how much of each hydrocarbon is contained in the …
This article is one of 5 important articles about Mud logging unit equipment. These articles explain in detail the equipment used in standard mud logging units to detect drilled gas. Surface logging is performed using the returning mud stream to communicate with the bottom of the borehole. There is a general relationship between the kind …
This article is one of 5 important articles about Mud logging unit equipment. These articles explain in detail the equipment used in standard mud logging units. Measured Depth Determination Depth is determined at the “Kelly down” position. This depth is the sum of the lengths of the kelly and the Drill String that are in …
This article is one of 5 important articles about Mud logging unit equipment. These articles explain in detail the equipment used in standard mud logging units. Surface mud logging is not complex in principle, does not interfere with the drilling process, and the results are available almost immediately. The Formation Evaluation Log (Figure 1-1) is …
Surface Mud Logging Basics & Theory Mud Logging was introduced as a commercial service in 1939. The service provides for continuous on-site inspection, detection, and evaluation of the rock units as they are being drilled with regards to correlation and potential hydrocarbon production. Correct methods of obtaining this data and its subsequent evaluation are very …
The Objective Of the Gas Show article is to: 1 Origin Of Gas Show The general definition of a “gas show” is a significant occurrence of hydrocarbon gases detected from the mud stream and identifiable as the result of the drilling of a specific increment of formation. One of the prime objectives of surface logging …
Samples are examined under a microscope for: The objective is to depict changes in lithology and the appearance of new formations. The microscope and ultraviolet light are complementary tools in reconstructing the characteristics of the originating strata. An estimate of the lithology, staining, and porosity percentages is made carefully since factors such as grain shape …
