horizontal drilling and hydraulic fracturing
Fracturing a horizontal well uses between 3 to 5 Million gallons of water – Delivered by truck or temporary pipeline – Stored in tanks or local or centralized impoundments Fracture Fluids 98 99 5 of slickwater fracturing fluid is water Each additive has an engineered purpose Proppant sand 15 HF FLUID COMPOSITION 162018 01 30 nbsp 0183 32 The combination of horizontal drilling and hydraulic fracturing has increased the rate of recent U S crude oil lease condensate and natural gas production Hydraulically fractured horizontal wells became the predominant method of new U S crude oil and natural gas development in October 2011 when total footage in linear feet surpassed all other drilling These types of drilling and completion technologies have also enabled the recent growth in production from shale and other unconventional oil and gas reservoirs in many parts of the world using a combination of hydraulic fracturing and horizontal extended reach drilling Some examples of advancements in drilling technology are presented below 2021 09 17 nbsp 0183 32 The expression Hydraulic Fracturing often called just fracking or fracing by the industry operators refers to a complex steering drilling directional or horizontal and high pressure fluid injection technology used to uncap mostly gas tight gas shale gas and coalbed gas coalbed methane and to lesser extent petroleum tight oil and shale oil trapped in the water and other materials used in hydraulic fracturing and other treatments that are dependent on geology and play location as well as available sources Figure 2 Percentage breakdown of cost shares for U S onshore oil and natural gas drilling and completion Source IHS Oil and Gas Upstream Cost Study commissioned by EIA Over time these costs have changed For

While directional drilling has existed since the 1930s its combination with hydraulic fracturing has changed the global energy landscape only in the past ten years Advances in horizontal drilling technology have allowed producers to reach 2017 02 03 nbsp 0183 32 The combination of horizontal drilling and hydraulic fracturing has made it commercially viable for oil producers to recover more oil and natural gas from shale formations The technology has made it possible to increase productivity in any given oil rich shale for greater recovery of oil and natural gas trapped in the rock Other BenefitsJohannes Fink in Hydraulic Fracturing Chemicals and Fluids Technology Second Edition 2020 Delayed hydrogen sulfide production Horizontal drilling in combination with hydraulic fracturing allows for more efficient extraction of natural gas from less accessible reservoirs 45 2017 04 26 nbsp 0183 32 Inadequate hole cleaning can lead to costly drilling problems such as mechanical pipe sticking premature bit wear slow drilling formation fracturing excessive torque and drag on drillstring difficulties in logging and cementing and difficulties in casings landing The most prevalent problem is excessive torque and drag which often leads to the inability of reaching Done together horizontal drilling and hydraulic fracturing can make a productive well where a vertical well would have produced only a small amount of gas Drilling Methodology Most horizontal wells begin at the surface as a vertical well Drilling progresses until the drill bit is a few hundred feet above the target rock unit At that point the pipe is pulled from the well and a
