What Is Tight Gas, and How Is It Produced? Tight gas is natural gas found in extremely impermeable and dense rock formations, often referred to as "tight" formations. It can also be trapped in unusually impermeable or nonporous sandstone or limestone formations, known as tight sands. Unlike conventional natural gas reservoirs, which can be drilled and extracted relatively easily, tight gas requires additional effort due to the restrictive nature of its surrounding rock. Without secondary production methods, such as hydraulic fracturing or acidizing, gas from tight formations would flow at very low rates, making extraction economically unfeasible., via rigzone https://lnkd.in/dt8YakeC (pict of Impermeable Pores in Tight Gas Formation, source: USGS) #unconventionalgas #petrophysics #seismic #directionaldrilling #hydraulicfracturing

As the Utica/Point Pleasant Shale EURs in the Oil Window of Ohio have moved from 5 BBLS/FT (2011) of completed lateral to 75+ BBLS/FT (2024) of completed lateral length, the wells that avoid geological hazards are still twice as good. EMF published a study in 2017 that aided in a step out and flurry of activity. Starting to see the words, "quiet acreage" coming up in interviews with large operators certainly makes us smile. The utilization of 3D seismic to assist with development will be key for the operators as basement generated structures get developed. This might be the only play in the Lower 48 that we don't know how far west it goes. Should be fun! #Oil #Gas #Appalachia #Ohio #Drilling #Utica #EOG

A drilling jar converts the potential energy stored stored in the elongated drill string into kinetic energy. After the jarring action occurs, this kinetic energy generates an impact wave that transmits a jarring force to the stuck drill string, helping to free it. Most modern drilling jars are hydraulic. They are also usually double acting, meaning they can deliver an extra-heavy impact should the bottom hole assembly become stuck. They are intended to work as an integral part of the drill string, and can withstand high pressures and temperatures over a long period of time, making them suitable for long-term use. #energyarchive #drillingjar #knowledgesharing #oilandgas #OilAndGas

This article discusses the causes and killing methods of underground blowouts in drilling operations. It starts by defining underground blowouts as the uncontrolled flow of formation fluids entering the wellbore at one point and leaving at any point other than the surface. The causes of underground blowouts are explored, including gas kick migration, bad killing practices, delay in shutting in the well, loss of circulation, and drilling through hydrocarbon-bearing reservoirs. The risks and challenges associated with underground blowouts are also highlighted, emphasizing the difficulty in analyzing and modeling the situation. Indications of an underground blowout and the methods of killing it, such as spotting a barite plug.... #drilling #OIL_AND_GAS #Adnoc

#The_Gas_Detection_Process: The gas detection process begins when drilling mud is circulated back to the surface, carrying formation gases with it. The mud passes through the shale shaker, where solid particles are separated. The remaining mud, which still contains gases, then flows to the gas trap. Here, the mud is agitated, causing the gases to separate and rise into the gas collection system. Once the gases are collected, they are transferred via the extraction line to the gas detector. The detector then analyzes the gas composition and concentrations. By measuring the levels of different hydrocarbons, mud loggers can determine whether the formation contains oil, gas, or a mixture of both. For example, higher 2

Hydraulic fracturing, also known as "fracking", is a process of drilling and injecting fluid into the ground at high pressure to fracture shale rocks and release natural gas or oil. The process has been used in the oil and gas industry for decades, but has seen a resurgence in recent years due to advances in technology. #petroleumengineering #Hydraulicfracturing

🔶A conventional reservoir represents a subsurface accumulation of hydrocarbons (like oil or natural_gas) confined by an impermeable rock layer, such as caprock. These reservoirs generally display high permeability and porosity, enabling hydrocarbons to flow smoothly to the well. Conversely, unconventional reservoirs are more difficult to reach due to their lower permeability and porosity. Examples include tight sands, shales, and coalbeds. Although developing these unconventional resources can be more complex and costly, they remain vital for our energy needs. To extract hydrocarbons from unconventional reservoirs, methods like hydraulic fracturing (fracking) and horizontal drilling are frequently utilized. #OilandGas #EnergyIndustry #HydraulicFracturing #HorizontalDrilling

The Power Behind Directional Drilling: Mud Motor Apparatus. In the world of directional drilling, precision and efficiency are key to hitting our target zones, especially in challenging subsurface conditions. One piece of technology that plays a pivotal role in this is the Drilling Mud Motor Apparatus. How does it work? The mud motor, powered by the drilling fluid (mud), converts hydraulic energy into mechanical energy, allowing for precise control over the drill bit’s rotation independent of the drill string. This is crucial when steering in directional drilling applications. Key Benefits: • Enhanced Control: Delivers more flexibility in directional changes. • Operational Efficiency: Reduces the need for surface adjustments, saving time. • Improved Wellbore Trajectory: Aids in achieving the desired well path with greater accuracy. As we advance in the oil and gas industry, innovations like the mud motor continue to push the boundaries of what’s possible, driving us toward better outcomes and optimized drilling performance. Excited to continue exploring these technologies and their impact in the field! #DirectionalDrilling #MudMotor #OilAndGas #Innovation #EnergyTransition #SLB #RAY #Haliburton #Bakerhughes #Weatherford

This revised edition of the guide to logging techniques offers a comprehensive yet accessible overview of the complex field of well logging. Divided into three main sections, the book covers the identification of oil and gas in Earth's formations, provides real-life examples of reading open-hole logs and interpreting the data, and explores recent advancements in logging tools and presentations. Additionally, the authors delve into cased-hole logs, including cement and casing inspection logs, reservoir monitor logs, and production logs. By the end of this book, readers will have a solid understanding of nearly every aspect of well logging. #shale #exploration #production #reservoir #oilandgas #welllogs #subsurace #energybooks https://buff.ly/3MquJEO
