Many of our projects consist of completing multiple horizontal remediation wells at one location. However, in many cases, vapor intrusion projects can be quite small, with only one or two short wells completed. At this site in a Midwestern state, Ellingson-DTD crews installed one blind (single-entry) horizontal sub slab pilot SVE well. The well was started behind and down gradient of the dry cleaner. Four-inch, schedule 80 PVC well screen and casing were utilized for the well materials. The total well length is 81’ with 50’ the well screened. Drilling conditions consisted of gravels and sand. Biopolymer drilling fluid was utilized for the drilling and well installation operation and well development consisted of fresh water and enzyme flushing and jetting followed by pumping to remove residual water.

How Deep Is An Oil Rig? An oil rig can operate in water depths ranging from 200 to 12,000 feet, with some advanced rigs capable of drilling down to depths of 30,000 to 40,000 feet below the ocean floor, depending on the type of rig and the location; the actual "depth" of the rig itself refers to the water depth it can operate in, not the depth it can drill to. Key points about oil rig depth: Deepwater rigs: Modern offshore oil rigs, like the Deepwater Horizon, can operate in waters as deep as 8,000 feet.  Drilling depth vs. water depth: While the rig itself may be floating in relatively shallow water, it can drill down to much greater depths below the seabed.  Different rig types: "Spar platforms" are a type of rig often used in very deep water, reaching depths of up to 11,500 feet Source - https://lnkd.in/dWejZSht #oilrig #oilfield #oil #oilandgas #drilling #offshore #oilrigs #oilandgasindustry #drillingrig #oilfieldlife #oilpatch #oilandgaslife #oilfieldstrong #riglife #rig #oilfieldtrash #glass #petroleum #headyglass #offshorelife #oilindustry #oilfieldproud #glassart #hightimes #onshore #crudeoil #glassbong #dab #petroleumengineering #engineering

Deepwater Pressure Management: Mud Weight (MW) Essentials: Mud weight forms an integral and vital component part in controlling the drilling operating window and wellbore pressure management requirements. It contributes to both direct and indirect indicators and is a key metric of the magnitude and extent of pressure and operating conditions that exist. Mud primarily provides the hydrostatic density and pressure as a function of vertical depth to support the range of wellbore formation pressures that exist in each section to be drilled. It serves to assure that no kicks, lost circulation, or wellbore instability events result in both static and dynamic operating conditions during all drilling operating activities conducted. If mud weight objectives and rheology properties are not met in full, notably in porous and high permeability formation intervals that commonly exist in deepwater, the resultant changes can cause and effect pressure management issues to arise, resulting in lost time events as fluids and pressures are either gained or lost to/from the wellbore. Lost time events then must be dealt with through suitable well control assurance, equipment, and best practices applied. Another probable scenario in deepwater is a low permeability formation interval. ◾️Example: shales where drilling “underbalanced” can perpetually result. This is because despite people best efforts and endeavors, operating conditions shall exist where mud weight and operating pressures exerted are less than the formation pressure (particularly when a connection is made, or circulation is stopped). In this case, low permeability prevents detectable measurable warning signs or indicators to result, e.g., fluid gains detected by the drillers, mud loggers. Problems often result once the first permeable formation is drilled and encountered. In such cases, higher kick level alertness practices shall be utilized. A “Higher alertness” mud weight strategy will vary considerably in response to pressures that exist even in similar stratigraphy, where wellbore, drilling conditions, and operating environments can rapidly change. In these instances, safe assurance, the drilling operating window, and mud weight pressures must be continually monitored and controlled. ◾️Example: In critical pressure regimes, deepwater wells can require a separate mud weight for drilling and tripping a particular wellbore sections. #drilling #oilandgas #oilfield #drillingrig #oil #petroleum #oilandgasindustry #drill #oilfieldlife #offshore #engineering #oilindustry

The Importance of Mud Circulation in Drilling Mud circulation is vital for cooling the drill bit, carrying cuttings, maintaining pressure, and stabilizing the borehole. Effective circulation enhances operational efficiency and safety, preventing blowouts and optimizing resources. #MudCirculation #Drilling #OilAndGas #PetroleumEngineering #WellControl

In a microgas tunnel (West of China), the total length of the tunnel is 2167 meters, of which the level IV surrounding rock section is 1020 meters long and the level V surrounding rock section 1093 meters long. Under the requirement of establishing active support system in tunnel construction, the application of radial prestressed anchor rod becomes particularly important. By the use of R25 built-in resin prestressed hollow grouting bolt (4m) can effectively solve the problem of resin anchoring agent falling off when the radial Angle is large, and improve the working time. Therefore, the build-in-resin prestressed hollow grouting bolt is used in the construction site. Under this construction technology, the integrated automatic operation of anchor drilling, loading and injection is realized through the procedures of drilling and cleaning, installing anchor rod, equal strength, applying prestress, locking nut and grouting in sequence, and the construction time of a single anchor rod is 8-12 minutes.

Boost Drilling Efficiency with Brightway's Mud Coolers! The Mud Cooler, also referred to as a Drilling Mud Cooler, Drilling Mud Chiller, or Drill Cool System, is a specialized piece of equipment designed to efficiently cool high-temperature mud during drilling operations. Cooling this way is currently a relatively efficient and safe method of mud cooling. It is generally erected in the mud pool to cool down the high temperature mud .The high-temperature mud from drilling wellhead can be cooled by achieving reduction of 30-50 °C temperature. Brightway can manfacture customized mud cooler with capacity of 120m³/h, 150m³/h and 180m³/h as per customer requirements. Our drilling mud cooling solutions are proven to: 1. Avoid the possibility of a well fire due to the drill head exceeding flashpoint temperatures. 2. Increase drill head life resulting in fewer pullbacks for the drill. 3. Eliminate non-production time to avoid significant financial penalties. #MudCooler #DrillingMudCooler #MudChiller #DrillCoolSystem #DrillingEfficiency #OilAndGas #DrillingOperations #WellSafety #Productivity

The shale shaker is a key component of the solids control system in oil and gas drilling operations. Its main function is to separate cuttings and other solid particles from the drilling fluid (also known as mud) during the drilling process so that the drilling fluid can be recycled and reused while maintaining its performance. The design features of the shale shaker are as follows: Design features Multi-stage screening: The drilling shale shaker is designed with multiple layers of screens, allowing for finer grading and separation. Efficient separation: The shale shaker is designed with high separation efficiency in mind to reduce drilling fluid loss and environmental pollution. Durability: The screen and frame are made of wear-resistant materials to withstand high-intensity use during the drilling process. Automated control: The shale shaker is equipped with an automatic control system that can monitor and adjust parameters such as vibration frequency and amplitude to optimize separation. Easy maintenance: The design takes into account easy maintenance features, such as a mechanism for quickly changing the screen. Drilling shale shakers are important equipment to ensure stable drilling fluid performance and reduce drilling costs and environmental impact. During the drilling process, effective solids control can significantly improve drilling efficiency and safety.
