It starts long before the first drill bit touches the ground. Geologists use seismic data to locate underground reservoirs where crude oil has been trapped for millions of years. Once a well is drilled and protected with steel casing, oil may initially flow to the surface W to the s under its own natural pressure. […]

A well kick is an entry of unwanted underground fluids into a wellbore, which can escalate into a blowout if secondary pressure controls fail. A kick happens when formation pore pressure is greater than the hydrostatic pressure exerted by the drilling fluid column. Causes of a Well Kick Low mud weight: The density or level […]

Hydraulic fracturing, often called “fracking,” is a well-stimulation technique used to extract oil and natural gas from deep bedrock formations. By injecting a high-pressure mixture of water, sand, and chemicals into the wellbore, energy companies create cracks in the rock, allowing trapped resources to flow more freely. How the Process Works? Drilling and Casing: A […]

The crosshead liners are bolted into the main frame. Special sealing washers are used under the heads of the bottom capscrews to seal and prevent oil leakage. Install the liners in the frame without shims, and tighten securely. Use micrometers and measure the inside diameter between the upper and lower liners at each crosshead position. […]

NOV 12-P-160 Mud Pump Assembly When Should the Intermediate Rod Be Replaced? 1. If the surface of the Intermediate Rod is scratched, scored, or pitted — for example, if it becomes scoured or scored, which can allow contaminants to enter the Power End assembly. 2. If the connection between the Intermediate Rod and the Crosshead […]

The mud circulating system is a closed loop system used in drilling operations to transport the drilling fluid down the well and back to the surface. www.goscoenergy.com Contact Us

Real-Time Wireline Logging refers to the continuous monitoring and transmission of downhole data to the surface in real time during a wireline logging operation. This allows engineers and geoscientists to make on-the-fly decisions while the logging tool is in the well. Typical Measurements Collected:Resistivity: Evaluates fluid saturation to determine if the rock contains water, oil, […]

While wax and paraffin deposition are often associated with production wells, they can also create significant challenges during tripping in (RIH) and tripping out (POOH) operations. As the drillstring is pulled or run in the hole, pressure and temperature changes can cause paraffin wax to precipitate from waxy crude oil. These deposits can accumulate on […]

Hydraulic fracturing is one of the most important stimulation techniques used in the oil and gas industry to increase production from low-permeability reservoirs such as shale, tight sandstone, and some carbonate formations. The process begins after the well has been drilled and cased. The target interval is perforated, creating pathways between the wellbore and the […]
