Sisal: a supervisory system for oil wells

Identification and ranking risks of horizontal directional drilling for oil & gas wells by using fuzzy analytic network process, a case study for Gachsaran oil field wells

Risk ranking of Horizontal Directional Drilling (HDD) for gas and oil wells is a key criterion in the project feasibility, pricing and for introducing a risk management strategy that aims to reduce the number of failures in the installation phase and its negative consequences. HDD is currently widely used in drilling wells in Iran, but research in the area of identification and risks ranking of...

A Torque Estimation Method to Aid an Intelligent Management System for Oil Wells Automated

This article presents a contribution for an oil wells intelligent management system called SGPA that nowadays manages about 700 oil wells using the rod pumping lift method at Bahia State, Brazil. The intelligent management system will be applied on oil wells using the gradual pumping method. In this oil pumping method, the torque on the rod is very important for detection of operational problem...

Using an Elastic, Expandable Sealant System for Zonal Isolation of Maroon Wells: a Laboratory Study

An oil and gas well cementing in Gachsaran formation, where sustained annular pressure has been reported in many wells, presents a big challenge in Maroon field. The main challenges are preventing gas migration and achieving zonal isolation using a competent cement sealant system which is able to withstand downhole stresses and high temperatures during production cycles. Unlike conventional cem...

The integrity of oil and gas wells.

Public concerns about oil and natural gas extraction these days inevitably turn to hydraulic fracturing, where millions of gallons of water, sand, and chemicals are pumped underground at high pressures to crack open rocks. Hydraulic fracturing often occurs a mile or more down, far from the water we drink or the air we breathe. The focus for safety and environmental stewardship should often be s...
