Development and Construction of a High Resolution Measurement While Drilling Tool

Mukul M. Sharma

Abstract

We propose to develop a revolutionary measurement while drilling (MWD) tool capable of measuring high resolution, real-time fluid saturations, and other parameters of oil and gas reservoirs. The prototype tool shall be built to meet requirements for high temperature, high pressure drilling service. The concept involves using a high rate of penetration anti-whirl drill bit designed to incorporate a ring of sensors coupled to a downhole data acquisition, storage and transmission system.

Injection Water Management

Mukul M. Sharma

Injectivity decline in water injection wells can have a large impact on the economics of offshore and onshore water disposal and waterflooding operations. Most mature oil and gas producing regions of the world currently have a ratio ofproduced water to oil in excess of 25 to 1. The disposal of produced water is, therefore, becoming an increasingly important issue in the management of produced fluids.

Integrated, Multi-scale Characterization of Imbibition and Wettability Phenomena Using Magnetic Resonance and Wide-Band Dielectric Measurements

Mukul M. Sharma, Carlos Torres-Verdin, Steven L. Byant (in collaboration with Professor George Hirasaki at Rice Unversity) (cverdin@mail.utexas.edu)

Funding amount: $800,000 for the period of Oct. 2004 - Sep. 2007

This research will use advanced dielectric and NMR measurements to understand and predict the flow of oil and water in reservoir rocks. Such improved characterization methods are vital for the continued production from existing domestic oil reservoirs at low cost and high efficiency.

Novel Fouling-Reducing Coatings for Ultrafiltration, Nanofiltration and Reverse Osmosis Membranes

Mukul M. Sharma, Benny D. Freeman (Chemical Engineering)

Funding amount: $576,000 for the period of Sept. 2004 - Aug. 2007

This research will provide new and better ways to purify produced water from oil and gas wells by using novel polymer membranes and thus will result in both environmental and economic benefits.

pH Sensitive Polymers for Improving Reservoir Sweep and Conformance Control in Chemical Flooding

Mukul M. Sharma, Steven L. Bryant, Chun Huh

Funding amount: $790,000 for the period of Oct. 2004 - Sep. 2007

This research will develop better ways to use polymers to enhance the oil recovery from depleted oil reservoirs and provide inexpensive oil from existing domestic oil reservoirs that might otherwise be uneconomic to produce and subject to abandonment.

pH Triggered Gels for Water Shutoff and Conformance Control

Mukul M. Sharma

As oil fields in the US mature, the volumes of produced water requiring disposal have increased significantly. With numerous older and mature oil fields, the growing problem of water production and stricter environmental regulation of water disposal are forcing oil producers to find ways to eliminate water coning and conformance control problems. Approximately 20 billion barrels of water are reinjected in the US every year. Any technology that minimizes the amount of water or gas produced in conjunction with the produced oil would have a significant impact on the energy consumption and on the cost oil production domestically.

Produced Water Management in Offshore Gulf of Mexico

Mukul M. Sharma

In offshore operations, topside equipment for produced water handling adds an enormous cost. It is imperative that we find cost effective solutions for treating this water in an environmentally benign manner. Seafloor separation coupled with sub-surface injection of produced water for waterflooding to recover additional oil is an excellent disposal strategy for the produced water that achieves three important goals:

Well Completion and Stimulation in Unconsolidated Sands

Mukul M. Sharma

Well completion and stimulation in unconsolidated formations has wide implications for the US petroleum industry. Most of the production in the Gulf of Mexico comes from unconsolidated sands. Frac-pack completions are being frequently performed in poorly consolidated, high-permeability sand formations to bypass well damage and enhance productivity. Despite the significance of the production from unconsolidated sands for the US, the design and placement of these completions in these sands is often sub-optimal due to lack of proper design tools.
