Kick occurrence is a possible event during a drilling process. It is required to be handled immediately using a well control method to avoid blowout, financial losses and damages to the drilling crew. Several methods including driller, wait and weight, and concurrent are applicable in the drilling industry to control a well during a kick incident. In this study, typical well control methods wer...

Shell must cease drilling well before the water freezes over lest a late-season blowout cause oil to accumulate under the ice through the winter.

Much has been written by economists about the sources of the productivity slowdown; and self-serving policy recommendations by interest groups abound. Strangely, the two are seldom connected. It is as if, upon seeing a neighbor jog his rounds more slowly than usual, we give him our expert advice without finding out why. But, surely, our advice to our neighbor must depend on the source of his la...

Renewable energy is seen as the future source for meeting the world’s growing demand, with geothermal offering a constant and independent supply. Tapping geothermal energy is not always straightforward as deep drilling is required in order to access this high -temperature resource. Geothermal drilling is expensive and is financed by the operator (usually districts or state representatives) with...

Drilling automation is a rapidly growing area of information technology development. Efforts within automation are being undertaken by numerous and diverse organizations in the oil and gas industry, partly due to a desire for exploitation of marginal and complex fields, and partly in order to increase safety of high risk operations. As offshore drilling occurs in a unique work environment, orga...

With rapidly growing global demand for energy resources, oil and gas exploration & production companies face mounting pressure to maximize supply and increase the rate of discovery for new energy sources. Increasingly operating in more remote locations and investing heavily in equipment and facilities, companies face greater financial and operational risks than ever before. Optimization of dril...

Directional drilling has evolved over the last few decades to become standard operational practice in the oil and gas exploration industry. One method of steering utilizes a technique known as magnetic Measurement While Drilling (MWD). Vector measurements of geomagnetic fields along a well-bore are used to determine it orientation. This method is advantageous in that it is inexpensive and effic...

This paper presents a time-varying sliding mode adaptive controller in order to handle the stick-slip oscillation of nonlinear rotary drilling system. The time-varying sliding mode controller with strong robust has two time-varying sliding surfaces, one of them induced time-varying integral sliding mode control can control the transient stage of the rotary drilling system and ensure the system ...

To meet the requirements of riser safety monitoring in offshore oil fields, a new Fiber Bragg Grating (FBG)-based bundle-structure riser stress monitoring sensor has been developed. In cooperation with many departments, a 49-day marine test in water depths of 1365 m and 1252 m was completed on the "HYSY-981" ocean oil drilling platform. No welding and pasting were used when the sensor was insta...

if solid wastes are not collected and disposed properly, can cause environmental pollution which affect human health, animals and plants. also aesthetic aspect of solid waste disposal is important. therefore proper management is necessary. this study was carried out for the identification and classification of solid waste produced by oil drilling company temporary camps based on rcra act and un...
