Oil Mud Testing Procedures 2018 | API SC13/TG3 Conference

1. API SC13/TG3 Oil Mud Testing Procedures2018 API E&P Winter Standardization ConferenceHyatt Regency – San Antonio, TexasTuesday – January 23, 2018 Chairman: Kim Burrows - Halliburton/Baroid

2. SC13/TG3Agenda • TG Charge • Roll Call • Previous Minutes Review and Approval • Work Group Reports • WG1-Perez (Hibernation – No report) • WG3-No Current Chair • WG4-Estes • Old/Continuing Business • New Business • Action Items • Adjournment

3. SC13/TG3Charge TG Charge: Recommend needed changes and develop test procedures for field and laboratory testing of oil-based drilling fluids. RP’s Affected: Recommended Practice for Field Testing Oil-Based Drilling Fluids - API RP 13B-2 Recommended Practice for Laboratory Testing of Drilling Fluids - API RP 13I

4. SC13/TG3Roll Call – January 23, 2018 Task Group Members:

5. SC13/TG3Review/Approve Previous Meeting Minutes • The June 2017 TG3 meeting minutes from the Summer conference in Calgary were emailed and are available for members to review • Call for a motion to accept the minutes and vote to approve Joe Perez – motion David Breeden – seconded

6. SC13/TG3 – OBM ProceduresWork Group Outline

7. SC13/TG3Work Group Reports – WG1 • Oil Mud Chemical Analysis (Salinity & Alkalinity) Chairman: Jose Perez • Charge: “Revise and improve existing OBM chemical analysis procedures for whole mud alkalinity, chloride and calcium.” • Status: Hibernation

8. TG3 / WG3Particle Size Distribution Testing of OBMs/SBMs No Current Chairperson Former Chairperson(s) Scott Klasner / Halliburton (Dr. Hongji Yuan – acting Chair) WG Charge: Propose a method(s) for determining PSD’s of NAF’s to be included in API RP13I. Scope: RP13I is for laboratory testing of drilling fluids. WG would form a workgroup to determine an appropriate standard procedure for particle size analyses of solids in an OBM or SBM using laser diffraction particle size analyzers. Pre-dispersion of the mud and optimum carrier solvents need to be investigated. Industry will be canvassed for current procedures and solvents selected. Round-Robins will be required to determine the optimum method. SPE or AADE paper possible.

9. TG3 / WG3Particle Size Distribution Testing of OBMs/SBMs . Progress: API to work on the appropriate wording/style – January 2017 Work group meeting to review API inputs Email recommended practice to the Task Group TG vote to adopt the RP – June 2017 Going into 13I for next ballot cycle

10. TG3 / WG4Measurement of NAF Internal Phase Activity Modifiers Chairperson Brent Estes - Chevron Charge: Validate activity measurements for estimating concentrations of Potassium Acetate as the activity modifier in NAFs. Recommend a methodology for using Potassium Acetate concentrations to calculate low gravity/high gravity solids content in NAFs.

12. TG3 / WG4Measurement of NAF Internal Phase Activity Modifiers • June 27th meeting (API conference): • Reviewed previous Action Items • Reviewed humidity standards from Rotronic data • Round Robin testing varying MW and OWR • 70/30 (10,12,14 ppg) completed • Action items • Continue current Round Robin (estimated completion – January 2018) • Check on retort data and determine if samples are available to send to Q’Max – Estes • Check on sample testing dates – Otto • Re-run data from NOV on the 70/30 OWR samples - LaCombe • What is the effect the raw data has on the solids concentration calculations - Perez

13. SC13/TG3 - Continuing Items Team members for B2 Revision Current document: 5th Edition – April 2014 Joe Perez and Kim Burrows to lead the team

14. SC13/TG3 - New Items TG3 should form a WG to evaluate electronic instruments, like the Salunda MudChecker, that can be used to perform a solids analysis on NAF emulsion fluids. If nothing else a tech report or tech bulletin could be issued even if nothing could be developed into a RP. 1/23/18 Meeting discussion: a WG0 team will form to discuss scope and potential charge. Some consideration will be given as to whether a WG within TG3 or a new TG should be formed. Shannon Stocks will take the lead.

15. SC13/TG3 - New Items Email from John Buflod received 1/19/18: I received this email pointing out a discrepancy in the thermometers used in calibrating viscometers. Do we need to issue an errata for 13B-2? Please be aware that we have found a discrepancies in thermometer accuracy acceptance used while calibration viscometer used to measure drilling fluid rheology in 13-B1 and 13-B2. This issue has been discussed while monthly conference call meeting of MENA AP region labs last Tuesday. According to API-13A, The which is the same as in API 13-B1, but it differs than what is mentioned in API 13B2 (±1 °C (±2 °F)

16. Email Feedback From Fred Growcock: Discussion: Errata to be prepared by Bernard Fraboulet From Paul Scott:
