Geosteering is “the drilling of a horizontal or other deviated well, where decisions on well path adjustment are made based on real-time geologic and reservoir data. In conventional directional drilling, the well path is steered according to a predetermined geometric plan. The objective is to follow the line as closely as possible. Geosteering is a …
The oil and gas companies have integrated into today’s energy marketplace. They have contributed to augmenting the global economy worldwide. These corporative firms play a significant role in providing cost-effective and high-quality fuel sources to ameliorate the living standards of society. The Covid-19 pandemic has dramatically mitigated the supply of oil and gas reserves in …
It will be recalled that the upward velocity of the mud in the annulus between the drill pipe and the wall of the hole is an important consideration with the function of drilling fluid of removing drilling cuttings. The usual expression of this annular velocity is in feet per minute. Annular Velocity Calculations & Formula …
The non-magnetic drill collar is made from specially treated steel alloys so that it does not affect magnetic surveying instruments. They aim to isolate directional survey instruments from magnetic distortion due to the steel drill string. Non Magnetic Drill Collar Function The magnetic survey instrument is influenced by the presence of a magnetic field around …
This is one of the types of casing with connections that can be run through the conventional casing (or other expandable casing) and then expanded to a larger diameter than a conventional casing run through that same size pipe. While this is a relatively new technology, it has seen some good success in numerous applications. …
Kill sheets are used to calculate the mud weight, mud quantities, and pumping times required to bring a well back to primary control after a gas kick. A description of how to complete kill sheets will be discussed in this article. The kill sheet is a printed form that contains blank spaces for recording information …
In this article, we will discuss the practical right steps for the single-stage primary casing cementing job procedure in oil and gas wells. We have also discussed the multi-stage cementing job in one of our articles before. And we have summarized the important tips for successful primary cementing & Casing Cementing calculations to assist you …
The system used for closing the BOP’s is a high-pressure hydraulic fluid accumulator unit. Hydraulic fluid is stored under pressure, the pressure being provided by stored nitrogen. When hydraulic oil is forced into the accumulator by a small volume, high-pressure pump, the nitrogen is compressed, storing potential energy. When the BOP’s are activated the pressured …
A Blowout Preventer (BOP) Control System as one of the drilling rig components, is a high-pressure hydraulic power unit fitted with directional control valves to safely control well kicks and prevent blowouts during drilling operations. A typical system offers a wide variety of equipment to meet the customer’s specific operational and economic criteria. The following …
Drilling engineers play a crucial role in the petroleum industry, designing and creating efficient drilling projects. To complete projects, a drilling engineer must comprehensively understand engineering principles. Daily, an engineer oversees all aspects of a drilling project, from the initial planning stages to execution and completion. This includes determining daily costs, managing mobile drilling units, …
