Case Study: Use of Remotely Operated Technology Saves 45 Hours Rig Time

Remotely operated barrier valve and bridge plug increase operational efficiency while eliminating a number of intervention runs CHALLENGE – Chevron wanted to hydraulically set a production packer and provide dual well barriers with minimal intervention methods. The completion design had a limitation where only low pressure could be applied against the fluid loss device, hence the requirement for a separate packer-setting solution. The typical completion method...

Case Study: Source Control Operations Achieve Success on Offshore Drilling Platform

Boots & Coots team controls fire and manages source control operations after offshore blowout CHALLENGE – During drilling operations on a platform, a kick occurred after encountering an unexpected abnormal pressure formation. While circulating out the kick, a leak developed on the blowout preventer (BOP) stack, which then ignited. The platform was safely evacuated without any injuries, but the fire eventually degraded the structural integrity of...

Holistic Management of Heavy Oil Field Development in Sensitive Environments

Extend the lifespan of a reservoir through heavy oil development while reducing environmental impact The exploitation of heavy oil faces two crucial challenges: reducing the cost of production per barrel; and increasing the recovery factor to extend the productive life of the reservoir. Both of these must be tackled while working to leave no environmental footprint. Technological developments have played a fundamental role in increasing well production in areas...

Tech Paper: Innovative Sidewall Pressure Coring Technology Improves Reservoir Insight in Multiple Applications

New tool helps eliminate the loss of important reservoir fluids during core recovery process Oil and gas exploration and development projects require reservoir properties that need to be evaluated to help ensure both economic and operational success. These reservoir properties include determination of the volume of original hydrocarbon in place, the residual hydrocarbon saturation after sustained production, and the reservoir drive mechanisms. Additionally, an accurate analysis...

Tech Paper: Improving Fiber-Optic System Reliability in Permanent Installations

Monitoring the health of fiber-optic system can save time and money Permanent installation of fiber-optic (FO) sensors, whether discrete or distributed, provides beneficial monitoring of a wide variety of parameters during every stage of a well’s useful life—from drilling and completions, through the productive period, up to and including permanent abandonment—assuming that the sensors do not fail during installation or subsequent wellbore intervention operations. Long-term reliability...

Case Study: RapidStage® system with AccessFrac® service shines in the Bakken

A minimum of 30% sustained production improvement in over 20 jobs performed CHALLENGE – Operators in the Bakken and Three Forks formations seek to increase compartmentalization in their wellbores by adding more isolated fracturing stages. The goal – access more productive reserves thereby improving well economics with the goal of lowering cost per BOE. At the same time, these operators strive to minimize completion time in...

Tech Paper: Efficient Use of Data Analytics in Optimization of Hydraulic Fracturing in Unconventional Reservoirs

Understanding reservoir parameters can help successfully optimize fracturing treatments per well Hydraulic fracturing operations affect reservoir flow dynamics and increase production in unconventional tight reservoirs. The control of fracture growth and geometry presents challenges in formations in which the boundary lithologies are not highly stressed in comparison to the pay zone, thus failing to prevent the upward migration of fractures. Several factors influence the growth and...

Case Study: RapidStage® ME Frac Sleeve Systems Help Seneca Increase Efficiency in Extended Reach Laterals

Multi-Entry Completion System Reduces Completion Cycle Time CHALLENGE – Seneca needed to complete an extended reach lateral (ERL) well with an efficient, cost-effective, low risk solution. In ERL wells, all operations and their risks are amplified due to the intense nature of the well’s conditions. Extreme measured depths lead to higher risk coiled tubing operations and extended run times for both coil and wireline units. This...

Tech Paper: Nonexplosive Tubing Perforator Offers Controlled Cost-Effective Solution for Through-Tubing Gas Lift Installation

User friendly mechanical perforator eliminates need for explosives, helping to improve safety and reduce rig time An operator in Baku, Azerbaijan was planning to create a gas lift configuration and needed to perforate 7-in., 32-lbf, 13% chrome, up to 0.51-in.wall thickness, heavy wall tubing without explosives. A nonexplosive mechanical tubing perforator conveyed on electric line avoided damaging the in-situ control lines and the casing. To meet...

Tech Paper: Size Degradation Studies of Lost Circulation Materials in a Flow Loop

When drilling problem zones in mature fields, it is important to use resilient lost circulation materials Recently, there has been significant interest in understanding the material properties of lost circulation materials (LCM), including size degradation studies from mechanical compression tests and from shear flow. These types of tests are currently of particular importance because of increased drilling activity in mature fields, which often require LCMs as a...
