Tech Paper: Study of Multilateral-Well-Construction Reliability

Examining 22 years of actual multilateral-well applications to determine true reliability Multilaterals are often cited as technology that can be implemented to maximize reservoir-recovery rates. However, few operators have been willing to put multilaterals into practice. The most frequently cited reason for not considering multilaterals is risk. Without access to data to show otherwise, it is difficult to overcome this industry perception of...

Case Study: Operator Saves USD 7.2 Million with Improved Drilling Performance and Sets New Field Benchmark

DES helps operator reduce drilling with potential savings of USD 115 million across field CHALLENGE – These shallow-water wells were typically drilled in about 93–105 days because of many factors, such as trajectory management, bit selection, limited hole cleaning, and bit hydraulic power design. Thus, the rate of penetration (ROP) and the additional time spent for hole cleaning were not optimal. To keep...

Mature Field Rejuvenation with Top Hole Re-completion –Using Cement Packers

Accessing bypassed oil to capture bypassed cash-flow The oil and gas industry has been hard-hit by the economic downturn. We find ourselves dealing with an unprecedented situation: most financing channels are at punitive rates, and the equity capital markets are an option only for a select few. With oil prices only slowly recovering, there is an industrywide sense of urgency to identify ways...

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...

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...

Case Study: Illusion® Frac Plug Helps Eliminate High-Risk Millout Operations

Operator removes risk of intervening in a depleted wellbore when milling out composite plugs CHALLENGE – For upcoming high-density well-spacing trials, the operator primarily wanted to remove the risk of intervening in the depleted wellbore when milling out composite frac plugs. Those risks, unmitigated, can put higher-density drilling programs at risk due to the steep costs and time delays created when millout challenges...

Tech Paper: Offshore Coiled Tubing Interventions Maximized the Value of Watered Out Mature Fields…

Coiled tubing helps sustain production in deep sandstone formations Saqqara is a very challenging field in the Gulf of Suez in the Red Sea area, producing from the deep sandstone Jurassic formation. This formation can sometimes be watered out, with a combination of high H2S and CO2 levels in the production. High sand quality has developed high horizontal and vertical permeability, which challenges...

We Can Help Maximize the Value of Your Mature Fields in this Market Downturn

The Halliburton collaborative framework for mature fields’ diagnoses challenges, designs solutions to improve production and increase recovery, and delivers these solutions to enable you to maximize the value of your assets. In a recent project, we found potential for a client to increase their total production by over 250%, with a rate of return of over 200%, within a matter of months. These...

Tech Paper: Advanced Geosteering Technology Promotes the Accuracy of Well Placement in the Thin Reservoirs of China Mature Oilfield

Safely and efficiently maximize reservoir exposure in mature fields After more than a decade of producing oil from the thick marine sand reservoirs in the HaDeXun oil field in the Tarim basin of western China, focus has shifted to the challenges of drilling thinly laminated reservoirs. To maximize efficiency and production, geosteering services, as well as bottomhole assembly (BHA) and bit optimization, were...

Tech Paper: Developments in Sandstone HF Acidizing: HF Fluid Compatible with Na or K Brines and Carbonate-Laden Mineralogy for High Temperatures (360°F)

Aminopolycarboxylic acid chelating agent helps with the removal of mineral buildup in sandstone formations Using hydrofluoric (HF) acid for the removal of clays and silica minerals impairing permeability in sandstone formations requires fluids free of sodium or potassium ions. High temperatures (> 300°F) further limit HF acid use and its effectiveness because of potentially damaging effects to the formation and its corrosivity. This paper discusses...
