Cementing

The Railroad Commission of Texas (RRC) on Tuesday approved RRC staff-recommended revisions to proposed changes to commission rules governing casing, cementing, drilling and completion of wells; cathodic protection wells; and seismic holes and core holes. Changes were initially proposed in September in response to action by the Texas Legislature. The revised proposal for changes takes into account responses received by commission staff during a public comment period. The current 45-day public comment period will end at noon April 1. A public hearing is scheduled for 1:30 CST Feb. 21 at the RRC’s Austin office.

The Railroad Commission of Texas (RRC) has released the latest revised draft amendments of rules relating to the well integrity issues of well casing, cementing, drilling and completions, cathodic protection wells, and seismic holes and core holes. The draft revisions are being circulated for an informal comment period, which is to end Dec. 31. The revisions are in response to comments RRC staff has received so far. The proposals are working drafts that have not been finalized and have not been submitted to the Texas Register for publication for public comment. Revisions are proposed to rules relating to cement sheath thickness; drilling fluid programs; isolation of productive zones; surface casing testing; cement specifications, quality and requirements; new requirements for wells that are to be hydraulically fractured (fracked); minimum separation of wells to be fracked; and well control/blowout preventer and pipeline shut-off valve requirements. One of the proposed revisions would ban fracking at noncemented wells when the zone being fracked ends within 1,000 vertical feet of a usable aquifer.

The natural gas industry will miss out on the prize of shale if it can’t convince the public that development is safe, a Chevron Corp. executive told a Pittsburgh audience Thursday.

Pennsylvania’s Independent Regulatory Review Commission on Thursday approved proposed rules that would tighten regulations on oil and gas well drilling.

The Pennsylvania Environmental Quality Board (EQB) has approved, by a 14-1 vote, a proposed set of stringent rules regarding how natural gas wells are constructed.

The American Petroleum Institute (API) Monday published a new guidance document outlining current best-industry practices for the proper drilling and cementing of wells that are being hydraulically fractured. The document, “Hydraulic Fracturing Operations — Well Construction and Integrity Guideline,” is designed to ensure that shallow ground water aquifers and the environment are protected throughout the drilling, completion and production phases of a well’s life, according to API. “The guidance document helps supplement and support existing state regulations to ensure that development of our nation’s abundant natural gas resources is safe and effective,” said API Upstream Director Doug Morris. A free .pdf of the guidance document is available at www.api.org/Publications/epstandards/. A hard copy may be purchased for $40 from www.api.org/publications or by calling IHS at (800) 854-7179.
